The CPU-111-10 utilizes 10Gb Ethernet (10GbE) to provide high-speed interconnection paths between the CPU,
both XMC sites, the backplane, and a front panel SFP+ module. The 10GbE architecture is shown below.
3.4.1 Fulcrum FM3224 Switch
The FM3224 10GbE Switch is the heart of the CPU-111-10 SBC. Using 10Gb Ethernet, it connects the backplane to
the CPU, XMC Modules, and front panel SFP+ Fiber Optic I/O modules (not included with the CPU-111-10).
The FM3224 is a fully integrated single-chip wire-speed 10G Ethernet switch. In addition to enhanced layer-2
functionality, the FM3224 layer-3 capabilities include advanced classification, extensive congestion management, and
improved switch management flexibility.
Features of the FM3224 include:
300nS Latency
Advanced Policy Engine
Switch Virtualization and Scaling
Port and MAC Based Security
In-band Switch Management
Provides Full-Mesh connectivity between up to eight VPQ Node Boards
Support for Front Panel SFP+ Connector for Copper or Fiber Optic cables (Configuration
The 82599 provides a high-speed CPU path into the switch fabric for both data and switch management . The
interface to the switch consists of dual-channel XAUI (IEEE 802.3ae). The 82599 connects via x8 Gen2 PCIe to the
PEX8624 PCIe switch and from there to the CPU. As previously mentioned, the 82599 also supports IEEE 1588
precision time protocol (PTP) by time stamping in-coming and out-going data packets.
The AEL2005 is a bidirectional single-channel 10 Gigabit Ethernet transceiver containing integrated EDC (Electronic
Dispersion Compensation) circuits targeted for 10GBASE-LRM optical modules and 10Gbps SFP+ applications.
The SFP+ connector is located on the CPU-111-10 front panel.
3.4.4 VPX 10Gb Ethernet I/O
Seven ports from the FM3224 10GbE switch are connected to the VPX backplane. The CPU-111-10 complies with
the VITA 46 OpenVPX standard for profile MOD6-PAY-4F2T-12.2.2-5. This profile covers the four 10GbE
channels on VPX connector P1. The remaining three 10GbE channels connect to P2, P4, and P5.
Each XMC site supports one 10GbE channel to provide a high-speed data path into the 10GbE switch fabric.
3.5 VPX General Purpose I/O
The CPU-111-10 provides general purpose I/O via VPX connector P4. This I/O can be connected to a rear transition
module or can be terminated on the backplane. The I/O consists of (4) SATA ports, (4) USB ports, (1) LPC bus, (1)
RS232/RS485 Serial Communications Port, (2) 1GbE SERDES channels, and (2) 1000BASE-T 1GbE ports.
3.6 Clocking
An IDT ICS9LPR501 CK505 Clock Synthesizer generates the majority of clocks used on the CPU-111-10. It
generates 100MHz differential clocks used by the CPU and PCIe peripherals. It also generates 48MHz, 33MHz, and
14MHz clocks used throughout the CPU-111-10. Clocks for DDR SDRAM are generated by the MCH. Separate
312.5MHz and 125MHz oscillators provide clocks to the FM3224 10GbE Switch.
A block diagram of the CPU-111-10 reset structure is shown below. The ispPOWR1220A provides reset glue logic
for the board. The backplane system reset (BP_SYSRST#) is an input when the CPU-111-10 is installed in a
peripheral slot and an output when installed in the system controller slot.
When all non-core supplies are up and stable, the ICH9R release the platform reset, or PLTRST#. The 1220A
buffers this reset and distributes it throughout the board as PLTRST1# and PLTRST2#. When PLTRST# is released
and the CPU core supply is stable, the CPU reset is released and the board boots up.
The CPU-111-10 utilizes an SMBus to support inter-chip communications. This can range from management
functionality, e.g. reading temperature sensors, to setting up application specific operational conditions in the various
peripheral components. The SMBus runs at a maximum speed of 100KHz.
The ICH9R SMBus connects to the MCH and an I2C Bus Multiplexer, where the bus is then distributed around the
board. A separate SMBus connects the ICH9R to the FM3224 10GbE Switch to support initialization and out-ofband switch management.
SMB_A is connected to the CK505 Clock Generator, the DB400 Clock Buffer, the ispPOWR1220A power
monitor/sequencer, various Temperature monitoring devices, and an I2C bus expander.
Figure 9: SMBus Architecture
The I2C bus expander provides GPIO for reading the board geographic address, system controller status, and the
VPX backplane non-volatile memory read-only (NVMRO) status.
SMB_B is connected to the PEX8624 PCIe switch, the 82599 Dual 10GbE controller, 82571 dual 1GbE controller,
both XMC sites, the front panel SFP+ connector, and to a rear transition module via the VPX backplane.
The MCH provides one SMBus port which connects to two serial presence detect (SPD) EEPROM's containing
memory initialization parameters.
There are 11 major supply rails on the CPU-111-10. A block diagram of the power supply architecture is shown
below. The VPX backplane provides +12V and +5V supplies. The majority of the on-board supply rails are
generated by Linear Technology LTM4616 16A MicroModules. A discrete DC-DC converter controlled by an
Intersil ISL6314 provides the CPU core supply. Two switching FET's control backend 3.3 and 5V power. -12V is
generated by an LTC3693 1A regulator and is only used by the dual PMC sites. Power monitoring and sequencing is
performed by a programmable Lattice ispPOWR1220A.
For input power requirements please refer to Appendix C.
The CPU-111-10 Rear Transition Module (RTM) provides I/O support for the CPU-111-10 SBC. This "Module
Specific I/O" capability of the CPU-111-10 provides rear chassis I/O for a SFP+ CX4 Copper/Fiber interface port,
Four External SATA (eSATA) ports, Two USB ports, dual 1Gb Ethernet ports, a RS232/485 Console port, and a
VGA port.
Four 2mm headers are provided to support CPU-111-10 PMC Module I/O. J1 and J3 terminate the signals derived
from PMC J14 and J2 and J4 terminate signals from J24. Please refer to Appendix D for RTM pin assignments.
The following sections cover the steps necessary to configure the CPU-111-10 and install it into a 6U VPX system
for single-slot operation. This chapter should be read in its entirety before proceeding with the installation.
4.1 Selectable Options
This section explains how to set up user configurable jumpers.
The CPU-111-10 is shipped in an antistatic bag. Be sure to observe proper handling procedures during the
configuration and installation process, to avoid damage due to electrostatic discharge (ESD).
The CPU-111-10 supports two PMC/XMC sites, an SFP+ connector, and an optional USB port. Front panel
indicators consist of a green power on LED, a red CPU Error LED, a yellow System Controller LED, and a yellow
solid state drive activity LED. A small hole is provided for access to recessed reset switch.
The CPU-111-10 uses General Software’s Embedded BIOS with StrongFrame™ Technology, Rev 6.The BIOS is
configured with the System Setup Utility, accessible from the Preboot Menu. This photo shows the initial splash
screen that is displayed after powering up the system as the BIOS runs through the Power On Self Test (POST).
When your system is powered on, Embedded BIOS tests and initializes the hardware and programs the chipset and
other peripheral components.
To enter the Setup mode, please press the delete <Del> key on your keyboard after powering up your system, during
POST.
B.1 Redirecting to a Serial Port
Setup may be run from the main keyboard and video display or from a terminal emulator program running on a host
computer connected to the system through a serial cable. To use a serial port, connect a dumb terminal or a PC
running a terminal emulation utility like Hyperterminal to COM1 via a null modem. Next, set the communications
parameters of the host’s terminal program to 115Kbaud. Other parameters are 8-bit, no parity, and one stop bit. Do
not enable XON/XOFF or hardware flow control.
With this link set up, power on the system. Press ^C a few times on your dumb terminal or your PC as the system
boots. POST will redirect to the serial console, and after it has completed its early stages, it will start the preboot
menu.

B.2 Setup Menus
The standard Embedded BIOS setup menus are described below in the order they generally appear in the menuing
system (Dynatem cannot vouch for support for all BIOS functions described in the subsequent sections):
B.3 Navigating Setup Menus and Fields
Navigation (moving your cursor around, selecting items, and changing them) is easy in theSetup system. The
following chart is a helpful user reference:
Reset an Enable/Disable or multiple-choice field, or back-up in numeric or string
fields.
Digits (0-9)
Used to enter numeric parameters.
Alphabetic (A-Z, a-z)
Used to enter text data on ASCII fields such as email addresses.
Special symbols
(!@#$%^&*_-+={}[], etc.)
Used to enter special text on ASCII fields that permit these characters.
BIOS Version
Indicates the major and minor core architecture versions (6.x, where x is a number from
0 to 999.)
The basic idea when using the Setup system is to navigate to the menus containing fields you want to review, and
change those fields as desired. When your settings are complete, navigate to the EXIT menu, and select “Save
Settings and Restart”. This causes the settings to be stored in nonvolatile memory in the system, and the system will
reboot so that POST can configure itself with the new settings.
After rebooting it may be desirable to reenter the Setup system as necessary to adjust settings as necessary.
Once the system boots, the Setup system cannot be entered; this is because the memory used by the BIOS
configuration manager is deallocated by the system BIOS, so that it can be used by the OS when it boots. To reenter
the Setup system after boot, simply reset the system or power off and power back on.
B.4 Main Setup Menu
The first menu always showing in the Setup system is the Main menu (unless disabled by the
OEM.) This menu is shown in Figure 3.1 below.
The Main menu provides a system summary about the BIOS, processor, system memory, date and time, and any
other items configured by the OEM. The BIOS information is obtained by Setup from the internal system BIOS build
itself; this information is useful when obtaining support for your system.
PLEASE CALL Dynatem at (800)543-2830 FOR BIOS SUPPORT; DO NOT CALL GENERAL SOFTWARE
DIRECTLY.
Date in MM/DD/YY format on which Dynatem built the system BIOS binary file.
System BIOS Size
Size of BIOS exposed in low memory below the 1MB boundary. Commonly, 128KB
would mean that the BIOS is visible in the address space from E000:0000 to
F000:FFFF.
CPM/CSPM/BPM
Modules
Indicates the names of the key architectural modules used to create the system BIOS
binary file. The CPM module provides the CPU family support; the CSPM module
provides the northbridge support; and the BPM module provides the board-level
support.
The CPU information is normally obtained by querying the Processor Brand String in the CPU’s MSRs; the method
used to achieve this is beyond the scope of this document.
The system memory information does not describe physical RAM; rather it describes the RAM as configured,
subtracting RAM used for System Management Mode, Shadowing, Video buffers, and other uses. This provides
realistic values about how much memory is actually available to operating systems and applications.
The Real Time Clock fields are editable with keystrokes. To navigate through the MM/DD/YYYY and HH:MM:SS
fields, use the TAB and BACKTAB keys. The hours are normally specified in military time; thus 13 means 1pm, or
one hour after noon, whereas 01 means 1am, or one hour after midnight. When the cursor leaves RTC fields, they
either affect the battery-backed RTC right away, allowing the system to continue with your new settings, or
they revert back to old values if the new values are not valid entries.
B.5 Exit Setup Menu
The Exit menu provides methods for saving changes made in other menus, discarding changes,
or reloading the standard system settings. This menu is shown in Figure 3.2 below.
To select any of these options, position the cursor over the option and press the ENTER key.
Pressing the ESC key at any time within the Setup system is equivalent to requesting “Exit Setup
Without Saving Changes.”
“drive name” – The system BIOS may list the drive’s
name in a generic sense (i.e., “USB Hard Drive”) if
the drive has not been detected yet, or the drive’s
full manufacturing name and serial number (if
Boot from the MBR/PBR of the named BIOSaware IPL drive
(BAID). The drive may be Legacy Floppy, PATA, SATA,
Compact Flash, or a USB drive.
B.6 Boot Setup Menu
The Boot menu allows the system’s boot actions and boot devices to be configured. This menu is shown here:
The BBS portion of this menu lists the devices and activities to be performed in the order in which they appear in the
list. When the BIOS completes POST, it follows this list, attempting to process each item. Some items are drives,
such as an ATA/IDE drive, or a USB hard disk, or CDROM.
The ordering of the drives in the BBS list controls the BIOS in several ways. First, it is the list of drives that is
scanned and assigned BIOS unit numbers for DOS (for example 80h, 81h, 83h, and so on for hard drives). If a drive
on the list is not plugged in or working properly, the BIOS moves on to the next drive, skipping the inoperative one.
Second, once the drives in the list have been verified, POST attempts to boot from them in that order as well. Drives
without bootable partitions might be configured, but skipped over in the boot phase, so that other drives on the list
become candidates for booting the OS.
The BBS list also contains other boot actions, such as boot from network cards and PCI slots, as well as special
BIOS boot actions like “Boot EFI”, “Boot Windows CE”, or even “Boot Debugger”. When deciding what boot
action to do first and then next in succession, POST first scans all the drives in the list to verify they are present and
operating properly (as described earlier in this section) and then goes down the list and tries to perform the actions in
order. During this boot phase, if the list item is a drive, an attempt is made to boot from the boot record of that drive.
If the list item is a device like a network card or PCI slot, an attempt is made to boot from that device. If the list item
is a software item like “Boot Debugger”, then it performs that action, and when that action completes, it moves on to
the next item in the BBS list.
The table that follows lists the set of standard boot action items:
Master PATA drive or SATA mapping by the chipset, routed
to the backplane via J5.
IDE1/Primary Slave
Primary Slave PATA drive or SATA mapping by the chipset,
routed to the backplane via J5.
IDE2/Secondary Master
Secondary Master PATA drive or SATA mapping by the
chipset, routed to on-baord CompactFlash
IDE CDROM
First detected IDE CDROM.
USB Floppy Drive
First detected USB floppy drive.
USB Hard Drive
First detected USB hard drive.
USB CDROM Drive
First detected USB CDROM.
Enter Board Information Browser
Invoke HTML Browser on 0.HTM in ROM.
Enter BIOS Setup Screen
Invoke System Setup Utility in ROM.
Enter BIOS Debugger
Invoke BIOS debugger in ROM.
Reboot System
Restart system.
Power Off System
Invoke S5 state, powering off system.
PCI Slot [n]
Boot from device in PCI Slot ‘n’.
Network
Boot from any network adapter.
SCSI
Boot from external SCSI device (on PMC/XMC card).
Boot EFI Binary
Boot EFI kernel from ROM or disk, depending on the EFI
source setting in the Features menu. If disk is selected, then
the BIOS searches all the configured disks in the system in the
order they appear in the BBS list, attempting to load
EFILDR.BIN from the root directory in the FAT file system
located on those drives.
Boot Windows CE Image
Boot Windows CE kernel from disk. The BIOS searches all
the configured disks in the system in the order they appear in
the BBS list, attempting to load NK.BIN from the root
directory in the FAT file system located on those drives.
Boot Graphical Desktop
Boot Firmbase GUI supporting graphical Firmbase
applications as well as booting DOS in a graphical window.
For applications requiring instant-on functionality even when
the OS is not available or is still loading.
The photograph above shows a common setup of the BBS list for desktop applications. In this example, the first boot
device is theWestern Digital IDE hard drive (WDC WD800JB-00JJC0) connected to the target as a Primary Master
IDE drive. The second boot device is the Secondary Master and this is the on-board CompactFlash. The third device
is a USB Hard Drive. A fourth boot device, “None”, is a placeholder that is simply used to add more entries in the setup screen; “None” is not actually executed by POST as a boot action item.
In addition to the BBS boot device list, there are two more sections in the BOOT menu; namely, the Floppy Drive
Configuration and IDE Drive Configuration sections. Both of these sections tell the BIOS what kind of equipment is
connected to the motherboard but the floppy drive interface has not been implemented so please ignore this and leave it as “Not Installed”. Similarly, the IDE Drive Configuration section describes the type of hard drive equipment that
is connected to the motherboard, including the cable type. IDE drives, or actually more properly Parallel ATA
(PATA) drives, are connected to the motherboard with a flat cable with either 40 or 80 wires running in parallel
(hence, Parallel ATA, as opposed to Serial ATA.) The 40-pin connector supports speeds up to UDMA2, whereas 80pin cables are needed for higher transfer rates to eliminate noise. The BIOS can be told what type of cable is
available, so that it knows whether higher transfer rates are allowed; or, it can be told to autodetect the cable type, in
which case the drive and the motherboard must both support the hardware protocol used to autodetect the drive’s
cable type.
Note: PATA cable autodetection sometimes fails with older drives, so 40-pin is the default, to ensure data integrity.
For higher performance, you should change this setting to 80-pin or AUTO if an 80-pin cable is installed.
B.7 POST Setup Menu
The POST menu is used to configure POST. This menu is shown in the following figure (scrolled down more so the
full set of options can be seen.) Be sure to review the Features menu, where additional items can be configured, such
as the Splash Screen and BIOS initiatives.
The figure below shows the same menu, scrolled down so that the remainder of its fields may be
viewed.
Enable/disable speaker click when testing each block.
Clear Memory During Test
Enable storing 0’s in all memory locations tested. Only necessary when some legacy
DOS programs are run, as they may rely on cleared memory to operate properly.
Pause on POST Errors
Enable pause when errors are detected during POST, so that the user can view the
error message and enter Setup or continue to boot the OS.
POST Display Messages
Enable display of text messages during POST. When disabled, POST is “quiet.”
POST Operator Prompt
Enable operator prompts if POST is configured to ask interactive questions of the
user about whether to load specific features; i.e., whether or not to load SMM.
POST Display PCI Devices
Enable display of PCI devices.
POST Display PnP Devices
Enable display of ISA PnP devices.
POST Debugger
Breakpoints
Enable processing of INT 3 (breakpoint) instructions embedded into option ROMs.
When enabled, if an INT 3 instruction is encountered, control is transferred to the
BIOS debugger, so that the option ROM can be debugged. When disabled, these
instructions perform no action.
POST Fast Reboot Cycle
Enable early reboot in POST, allowing service technician to verify that the hardware
can technician to verify that the hardware can reboot very quickly many times in
succession. Platform will continue to reboot after every boot until the system’s CMOS
is reset, as there is no way to enter Setup from this early point during POST.
POST Slow Reboot Cycle
Enable late reboot in POST, allowing service technician to cause the system to move
through POST and then reboot, causing POST to be reexecuted, over and over, until
Setup is reentered and this option is disabled. When left unattended, this is a
straightforward way of having POST exercise system memory and peripherals without
requiring a boot to a drive with an operating system installed.
POST Floppy Seek
Enable head seek on each floppy drive configured in the system. Used to recalibrate
the drive in some systems with older DOS operating systems.
POST Hard Disk Seek
Enable head seek on each hard drive configured in the system. This is a way of
extending the standard testing performed on each drive during POST, by requesting
that the drive actually move the head. Not available with all drives.
The following table describes the settings associated with the POST setup menu’s Memory Test section.
The following table describes the settings associated with the POST setup menu’s Error Control section:
The following table describes the settings associated with the POST setup menu’s POST User Interface section:
The following table describes the settings associated with the POST setup menu’s Debugging section:
The following table describes the settings associated with the POST setup menu’s Device Initialization section:
Enable PnP feature. When disabled, a PnPaware OS will not find any PnP services in
the BIOS, and all other configuration parameters in the menu will be greyed out.
Enable to support legacy OSes like DOS, Windows95, Windows98, and WindowsNT.
Disable for operating systems like WindowsXP or Windows Vista, or for Linux
operating systems with ACPI support.
Plug-n-Play OS
Enable delay of configuration of PnP hardware and option ROMs. When enabled,
BIOS will NOT configure the devices, and instead defer assignment of resources,
such as DMA, I/O, memory, and IRQs, to the PnP OS. When disabled, the BIOS
performs conflict detection and resolution, and assigns resources for the OS. Disable
this parameter when running non-PnP OSes like DOS. Enable this parameter when
running PnP OSes like Windows95, Windows98, and WindowsNT.
IRQ0
Enable exclusive use of IRQ0 by PnP.
IRQ1
Enable exclusive use of IRQ1 by PnP.
IRQ2
Enable exclusive use of IRQ2 by PnP.
IRQ3
Enable exclusive use of IRQ3 by PnP.
IRQ4
Enable exclusive use of IRQ4 by PnP.
IRQ5
Enable exclusive use of IRQ5 by PnP.
IRQ6
Enable exclusive use of IRQ6 by PnP.
IRQ7
Enable exclusive use of IRQ7 by PnP.
IRQ8
Enable exclusive use of IRQ8 by PnP.
IRQ9
Enable exclusive use of IRQ9 by PnP.
B.8 PnP Setup Menu
The PnP menu is used to configure Plug-n-Play, a legacy BIOS initiative used to support operating systems such as
Windows95, Windows98, and WindowsNT. ACPI has largely replaced this feature; however, it is necessary for
platforms to support older operating systems.
The PnP menu consists of two sections; basic configuration that enables Plug-n-Play and identifies if a PnP should
perform configuration or let the OS do it; and then, another section that defines which system IRQs should be
reserved for PnP’s use, so that PCI doesn’t use them. The following table presents the fields in the PnP menu.
The SIO menu is used to configure the LPC47B27x Super I/O device. The only implemented I/O on this chip are the
PS/2 mouse and keyboard and two 2-wire COM ports (COM3 & COM4). Basically this window is used to configure
COM3 & COM4 (though they are referred to as Serial Ports 1 & 2 in the SIO Setup Menu):
POST reads these settings in the menu shown above and programs the Super I/O part accordingly, enabling and
disabling devices as requested. The disabled devices are not further programmed, since they are actually disabled in
hardware. In the figure above, legacy I/O addresses and IRQs are as follows:
COM3 – I/O 3f8h, IRQ4.
COM4 – I/O 2f8h, IRQ3.
It should be noted that these are not the only possible addresses, but they are the ones that will ensure compatibility
with the most legacy software, especially early DOS programs that do not use BIOS to access the COM ports.
Enable time-optimized POST, causing certain preconfigured OEM optimizations to be
made when the system boots. Depending on the system, Quick Boot can reach the
DOS prompt in as little as 85ms (milliseconds.)
Advanced Power
Management (APM)
Enable legacy power management, used by the system when an ACPI-aware operating
system is not running (during POST, such as when the system is running the preboot
environment, or while running DOS, Windows95, Windows98, or Linux kernels below
version 2.6.) Uses the SMM feature (see Firmbase) to operate properly.
ACPI
Enable ACPI system description and power management (ACPI replaces PnP and
APM.) Used with ACPI-aware OSes such as Linux kernels version 2.6 and above,
Windows XP, and Windows Vista. Commonly also uses the SMM feature (see
Firmbase) to operate properly.
POST Memory Manager
(PMM)
Enable memory allocation services for option ROMs, especially network cards running
PXE. Some option ROMs may use this interface incorrectly, causing system crashes.
Other PXE option ROMs may not run if PXE is not supported. Because of the state of
these option ROMs, the setting is provided as an option to the user.
SMBUS API
Enable INT 15h services that permit certain software to access devices on the system’s
SMBUS without having knowledge of the SMBUS controller itself.
System Management BIOS
(SMBIOS)
Enable System Management BIOS interface specification support, exposing
information about the type of hardware, including the chassis, motherboard layout,
type of CPU and DRAM sticks, to applications such as WfM, which runs on PXE in
the preboot environment.
Manufacturing Mode
Enable automatic entry into manufacturing mode when POST encounters a critical
error. Used in closed device settings such as smart phones that need access to docking
stations when they don’t boot. Leave disabled.
B.10 Features Setup Menu
The Features menu is used to configure the system BIOS’ major features, including Quick Boot, APM, ACPI, PMM,
SMBUS, SMBIOS, Manufacturing Mode, Splash Screen, Console Redirection, and others added by the OEM. This
figure shows a typical Features Setup menu.
The following table describes each setting in the Features menu :
Configure the console redirection feature over a serial port. Automatic – causes
POST, the debugger, and the preboot environment to use the system’s first serial port
(COM1) when an RS232 cable is detected with DSR and CTS modem signals active,
indicating a terminal emulation program is likely to be attached to the other end of the
cable. Always – causes the BIOS to always use the serial port as the console, without
testing for the presence of the terminal emulation program. Never – causes the BIOS
to never invoke console redirection, but instead always use the main keyboard and
video display. If there is no keyboard or video display, the system operates headless.
EFI Source
Configure the location (ROM or disk) where the EFI boot action can find the
EFILDR.BIN image. An image may be merged with the system BIOS into the system
ROM, or it may be placed in the root directory of any bootable mass storage device.
Legacy USB
Enables BIOS support for USB keyboards and mice. Up to 8 USB keyboards and 8
USB mice may be supported at a time. Use of PS/2 keyboard and mouse concurrently
with USB devices is discouraged, as the legacy PS/2 keyboard controller cannot easily
separate simultaneous data streams from both device classes.
USB Boot
Enables BIOS support for accessing USB mass storage devices and emulating legacy
floppy, hard drive, and CDROM drive devices with them. Enable this option in order
for USB devices to be supported in the BBS device list(see the BOOT menu.)
EHCI/USB 2.0
Enables EHCI Firmbase Technology driver, allowing USB Boot feature to use high
B.11 Firmbase Setup Menu
The Firmbase menu configures the Firmbase Technology component of the system BIOS, including all of the features
enabled by it; i.e., legacy USB keyboard and mouse, boot from USB devices, and support of Firmbase applications
such as Boot Security, Platform Update Facility, and High Availability Monitor. This menu has several parts, with the
most basic user oriented feature options in the top section, and the more technical tuning parameters located in the
lower sections.
The following table presents the settings that enable high-level features enabled by Firmbase Technology:
Enables Firmbase Technology FAT file system driver, so that Firmbase applications
such as Boot Security, Platform Update Facility, and HA Monitor, as well as the HA
and TCB components of the kerne, have access to files residing on drives containing
FAT file systems. Also turn on this option if you wish to run Firmbase applications
from FAT file systems on either ATA or USB mass storage devices.
Firmware Application Suite
Enables Firmbase applications configured for the system by the OEM. Typically
includes Boot Security, Platform Update Facility, and High Availability Monitor.
Firmbase User Registry
Not used.
Firmbase User Shell
Enables Firmbase Technology command line interpreter, a multi-user command shell
with DOS-like and Unix-like command structure;can be used to start Firmbase
applications written with the Firmbase SDK, a General Software product.
Firmbase Technology
Enables Firmbase Technology as a whole, the industry’s most comprehensive and
fullfeatured System Management Mode (SMM) operating environment. Some
hardware platforms require Firmbase Technology to run, as they may use it to
virtualize hardware such as virtual video and audio PCI devices. Some BIOS features,
such as ACPI and APM, may require Firmbase Technology to operate
Firmbase Debug Log
Specifies the device used by Firmbase Technology components (kernel, drivers, and
programs) to display debugging instrumentation produced with the dprintf and
DPRINTF system functions.
None – Instrumentation disabled.
COM1 – Write text to 1st serial port.
COM2 – Write text to 2nd serial port.
COM3 – Write text to 3rd serial port.
COM4 – Write text to 4th serial port.
Virtual – Write text to virtual console
If enabled, this console can provide diagnostic messages (similar to the types displayed
by Linux when it boots) for Firmbase Technology features such as USB HID and USB
Boot.
Firmbase System Console
Specifies the device used by Firmbase Technology’s system process when it
initializes the kernel and processes the [SYSTEM] registry section, including its Start
and Run commands.
None – System console disabled.
COM1 – Write text to 1st serial port.
COM2 – Write text to 2nd serial port.
COM3 – Write text to 3rd serial port.
COM4 – Write text to 4th serial port.
Virtual – Write text to virtual console
If enabled, this console can provide a list of sign-on banners of all Firmbase
applications loaded during system initialization.
Firmbase Shell on Serial
Port
Specifies a serial port that may be used by Firmbase Technology’s command line
interpreter as an extra user session for systems that do not have a keyboard or monitor
to support virtual consoles.
None – Serial console disabled.
COM1 – Console on 1st serial port.
COM2 – Console on 2nd serial port.
COM3 – Console on 3rd serial port.
COM4 – Console on 4th serial port.
Virtual Console History
Specifies the number of lines of text that Firmbase Technology maintains in its virtual
console feature, allowing the user to scrollback through lines previously displayed and
scrolled off the screen. OEMs may configure a set of values, such as 20, 50, 100, 200,
and 500 lines.
Quiet Mode
Enables a feature that causes the Firmbase kernel to suppress its standard messages to
the system console.
Strict Mode
Enables a feature that causes the Firmbase kernel to abort any processes in the system
that make software errors in calling system API functions. Examples include blocking
at IRQLs other than IRQL_THREAD, or passing a NULL pointer to a C library
function that requires a non-NULL pointer, etc.
Disabling this feature causes the kernel to skip over the activity that discovered the
programming error in the application, allowing it to continue if at all possible, with
the consequence that the program may not operate correctly.
System Cache
Enables POST’s support for cache in the system. Modern processors virtually require
cache to be enabled to achieve acceptable performance. However, to diagnose certain
problems related to caching in the system, such as multiprocessing systems, it may be
desirable to disable this setting.
Keyboard Numlock LED
Enables the Numlock key when POST initializes the PS/2 keyboard.
Typematic Rate
Specify the rate at which the PS/2 keyboard controller repeats characters when most
keys are pressed down. USB typematic is automatic and does not use this parameter.
Typematic Delay
Specifies the amount of time a repeating key may be pressed on a PS/2 keyboard until
the key repeat feature begins repeating the keystroke. USB typematic is automatic and
does not use this parameter.
B.12 Miscellaneous Setup Menu
The Misc menu provides for configuration of BIOS settings that don’t easily fit in any other category. They include
Cache Control, Keyboard Control, Debugger Settings, and System Monitor Utility Configuration parameters.
The following table presents the settings in the Misc Setup menu:
Enables the display of hexadecimal numbers in the debugger with lowercase letters
instead of uppercase letters (ie, 2f8ah instead of 2F8AH.)
Proprietary Stimulation
Enables System Monitor’s callout to theOEM’s BPM adaptation code to execute code
that causes stimulation of the SMM environment for measurement purposes.
Hard Disk Read
Stimulation
Enables System Monitor’s read of a preconfigured number of sectors from a location
on the first hard disk in the system in order to stimulate the SMM environment. This is
useful when measuring code path lengths in USB boot, when the first hard drive is
configured in the BBS list as a USB hard drive.
Hard Disk Write
Stimulation
Enables System Monitor’s write of a preconfigured number of sectors to a location on
the first hard disk in the system in order to stimulate the SMM environment. This is
useful when measuring code path lengths in USB boot, when the first hard drive is
configured in the BBS list as a USB hard drive.
Please note that when this parameter is selected, the system automatically enables
reading, so that the stimulation of the system includes reading a range of sectors into a
memory buffer, and writing the same data back to the same range of sectors for safety.
Thus, this feature is theoretically nondestructive.
