1.6 Power Consumption and Temperature Range
The CP302 board is based on the Intel Mobile PentiumIIl processor. Intel has developed mobile processors to meet the specific needs of mobile PC's. As such, they operate at lower voltages than their desktop counterparts, are significantly smaller in size, consume less power and dissipate less heat. The design is optimized for low power consumption applications.
The goal of this description is to provide a method to calculate the power consumption for the CP302 base board and for additional configurations. The processor dissipates the majority of the thermal power.
The power consumption table lists the voltage and current specifications for the CP302 board and the CP302 accessories. The values are measured with a 8 slot passive CompactPCI backplane and two power supplies, one for the CPU and the other one for the harddisk. During the measurement the power consumption of the backplane can be ignored. The operating systems was DOS 6.22 without power management and Windows NT 4.0 with power management. The measured values varied, because the
power depended on the processor activity. All Mobile PentiumIIl processors are powered with 1.35V core voltage (low power version).
These values were measured at the DOS prompt and without the keyboard.

1.6.1 Temperature Range
The CP302 family are the first CompactPCI boards capable of operating over the extended temperature range from -40°C up to + 85°C. All onboard components are specially selected for the higher temperature range. For the higher temperatures the desktop processors are not suitable, because the power consumption is higher and the
allowable case temperature is lower. The only suitable processor is the Intel Mobile PentiumIIl processor family. These processors are produced with the new 0.18-micron
process which have lower power consumption and support higher case temperatures (100°C).
1.6.1.1 Temperature Range and Air Flow
These values have been measured with typical applications under DOS and Windows NT 4.0. In worst case situations the values and the temperature range must be reduced accordingly. For all situations the maximum case temperature of the Mobile Pentium III processor must be below 100°C. This temperature value can be measured with the onboard remote temperature sensor. In instances of overtemperature the hardware monitor will reduce the processor clock to lower the generated power.
0 m/s air flow means standard convection cooling with the board in an upright position. An airflow of 1 m/s is a typical value for a standard PEP ASM 4 rack ( 3U CompactPCI rack with 1U cooling fans ). For other racks or housings the available airflow will be dif­ferent. The maximum ambient temperature must be recalculated and / or measured for such environments. For the calculation of the maximum ambient temperature the pro­cessor case temperature must never exceed 100°C. The maximum heatsink tempera­ture depends on the physical characteristics of the heatsink and thermal connection to the processor. To ensure that the heatsink temperature does not exceed its limits an air­flow may be needed for a given ambient temperature. Heatsink temperature is mea­sured at the top of the heatsink base, closest to the processor.
Important Warning concerning overheating follows on next page

2.5 Peripherals
The following standard peripherals are available on the CP302 board:
Real-Time Clock
The real-time clock performs time-keeping functions and includes 256 bytes of general purpose battery-backed CMOS RAM. Features include an alarm function, programmable periodic interrupt and a 100-year calendar. All battery-backed CMOS RAM data remains stored in an additional EEPROM. This prevents data loss.
Counter/Timer
Three 8254-style counter/timers are included on the CP302 as defined for the PC/AT.
2.5.1 Watchdog Timer
A watchdog timer is provided, which forces an IRQ5, NMI or Reset condition (configurable in the watchdog register). The watchdog time can be programmed in 12 steps ranging from 125 msec up to 256 seconds. If the watchdog timer is enabled, it cannot be stopped.
2.5.2 Battery
The CP302 is provided with a 3.0V “coin cell” lithium battery for the RTC. To replace the battery please proceed as follows:
Turn off power
Remove the battery
Place the new battery in the socket.
Make sure that you insert the battery the right way round. The plus pole must be on the top!
The lithium battery must be replaced with an identical battery or a battery type recommended by the manufacturer. Suitable batteries include the VARTA CR2025 and PANASONIC BR2020
Important notes concerning the battery appear on the next page

CP302 Functional Description and Configuration
ID 21112, Rev. 05Page 2 - 10 ® PEP Modular Computers GmbH
2.5.3 Reset
The CP302 is automatically reset by a precision voltage monitoring circuit that detects a drop in voltage below the acceptable operating limit of 4.725 V for the 5V line and below
3.0V for the 3.3V line, or in the event of a power failure of the DC/DC converter. Other reset sources include the watchdog timer and local push-button switch. The CP302 responds to any of these sources by initializing local peripherals and issuing the PCIRST* signal on the CompactPCI bus.
The CP302 has a variety of reset options:
Front panel push button
Watchdog
Backplane reset (PRST input)
Power control (5V, 3.3V and CPU core voltage)
!
Important
• Care must be taken to ensure that the battery is correctly replaced.
• The battery should be replaced only with an identical or equivalent type recommended by the manufacturer.
• Dispose of used batteries according to the manufacturer’s instructions.
• The typical life expectancy of a 170 mAh battery (VARTA CR2025) is 4 - 5 years with an average on-time of 8 hours per working day at an operating temperature of 30°C. However, this typical value varies considerably because the life expect­ancy is dependent on the operating temperature and the standby time (shutdown time) of the system in which it oper­ates. To ensure that the lifetime of the battery has not been exceeded it is recommended to exchange the battery after 3 - 4 years.

2.5.4 SMBus Devices
The CP302 provides a System Management Bus (SMBus) for access to several system monitoring and configuration functions. The SMBus consists of a two-wire I2C bus interface. The following table describes the function and address of every onboard SMBus device.
2.5.5 Thermal Management / System Monitoring
The LM81 can be used to monitor several critical hardware parameters of the system, including power supply voltages, fan speeds and temperatures; all of which are very important for the proper operation and stability of a high-end computer system. The LM81 provides an I2C serial bus interface.
The voltages of the onboard power supply (+12 V, -12V, +5V, +3.3V, +1.5V, Vcore) are supervised. The onboard hardware monitor is able to detect the CPU fan speed and an external fan speed in revolutions per minute (RPM). The presence of the fans is automatically detected.
The integrated MAX1617 temperature sensors monitor the CPU temperature to make sure that the system is operating at a safe temperature level. If the temperature is too high, the sensors automatically reduces the CPU clock frequency, depending on the mode chosen in the BIOS set.

2.6.10 Rear I/O Interface
The CP302 board provides optional Rear I/O connectivity for peripherals for special compact systems. Some standard PC interfaces are implemented and assigned to the front panel and to the rear connector J2.
When the Rear I/O module is used, the signals of some of the main board/front panel connectors are routed to the module interface. Thus the Rear I/O module makes it much easier to remove the CPU in the rack as there is practically no cabling on the CPU board.
For this configuration two versions are available. One with 64-bit/33 MHz CompactPCI and reduced Rear I/O functionality and one with 32-bit/33 MHz and some Rear I/O peripherals.
For the system Rear I/O feature a special backplane is necessary. The CP302 with Rear I/O is compatible with all standard CompactPCI passive backplanes with Rear I/O support on the system slot.
The CP302 Rear I/O provides the following interfaces, all signals are available on J2 only when the board is ordered for Rear I/O functionality:
32-bit CompactPCI and Rear I/O
32-bit/33 MHz CompactPCI
PS/2 keyboard
PS/2 mouse
Two USB ports
Ethernet port without LED
Two COM ports
VGA CRT interface
Second EIDE port
Fan control input
The following ports may be used either for rear or front I/O, the combination of both rear and front is not possible.

2.9 Special Registers Description
The following registers are special registers for the CP302 to watch the onboard hardware special features and the CompactPCI control signals.
Normally, only the system BIOS uses these registers, but they are documented here for application use as required. Take care when modifying the contents of these registers as the system BIOS may be relying on the state of the bits under its control.
2.9.1 Watchdog
The CP302 has one watchdog timer. This timer is provided with a programmable timeout ranging from 125 msec to 256 sec. Failure to retrigger the watchdog timer within a set time period results in a system reset, SMI or an interrupt. These can be configured via the register 0x284.
To enable the watchdog bit 4 of the register 0x282 must be set. If the watchdog is enabled via bit 4” this bit cannot later be cleared.
With a write access to the register 0x280 the watchdog is re-triggered. Once the watchdog is enabled. Once the watchdog is enabled, it must be continuously strobed within the terminal count period to avoid expiry of the Watchdog..
2.9.1.1 Watchdog Trigger
A write access triggers the watchdog. The I/O location for the watchdog trigger is 0x280.
Watchdog Timer section appears on the following page

2.9.1.2 Watchdog Timer
The CP302 has one watchdog timer with a programmable timeout ranging from 125 msec. to 256 sec.
The I/O location for the watchdog configuration is 0x282.
2.9.2 Reset Control Register
This register controls the reset signal for the Ethernet controller and the VGA-AGP interface. A low signal keeps the chips in the reset mode. The default configuration is high.
The I/O location for the reset control register is 0x281.

2.9.3 Interrupt Configuration Register
The interrupt configuration register holds a series of bits defining the interrupt routing for the watchdog, the power control derate signal and the CompactPCI enumeration signal. If the watchdog timer timesout, it can generate three independent hardware events: reset, SMI and IRQ5 interrupt.
The enumeration signal is generated by a hotswap compatible board after insertion and prior to removal. The system uses this interrupt signal to force software to configure the new board. The derate signal indicates that the power supply is beginning to derate its power output.
The I/O location for the interrupt configuration is 0x284.

4. CMOS Setup
This chapter describes the Award BIOS Setup program, EliteBIOS, version 4.51PG. The Setup program lets you modify basic system configuration settings.
4.1 Proprietary Notice
Unless otherwise noted, chapter 4 of this manual, which concerns the EliteBIOS setup program, as well as the information herein disclosed are proprietary to AWARD Software International, Inc. Any person or entity to whom this document is furnished or who otherwise has possession thereof, by acceptance agrees that it will not be copied or reproduced in whole or in part, nor used in any manner except to meet the purposes for which it was delivered.
The information presented in this chapter is subject to change without notice, and should not be considered as a commitment by Award. Although Award will make every effort to inform users of substantive errors, Award disclaims all liability for any loss or damage resulting from the use of this document or any hardware or software described herein, including without limitation contingent, special, or incidental liability.
4.2 Introduction to Setup
This manual describes the Award BIOS Setup program. The Setup program lets you modify basic system configuration settings. The settings are then stored in a dedicated battery-backed memory, called CMOS RAM, that retains the information when the power is turned off.
A special feature of PEP’s CompactPCI boards is that all Setup information is additionally saved in a non-volatile serial EEPROM. This feature provides the user with enhanced data security in comparison with a standard PC board, because setup data will not be lost should the battery fail.
The Award BIOS in your computer is a customized version of an industry-standard BIOS for IBM PC AT–compatible personal computers. It supports the Intelx86 and
compatible processors. The BIOS provides critical low-level support for the system central processing, memory, and I/O subsystems.
The Award BIOS has been customized by adding important, but nonstandard, features such as virus and password protection, power management, and detailed fine-tuning of the chipset controlling the system.
The rest of this manual is intended to guide you through the process of configuring your system using Setup.

CP302 CMOS Setup
ID 21112, Rev. 05Page 4 - 4 ® PEP Modular Computers GmbH
Starting Setup
The Award BIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in CMOS RAM and begins the process of checking out the system and configuring it through the Power-on Self Test (POST).
When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands control of system operations to it.
During POST, you can start the Setup program in one of two ways:
By pressing <Del> immediately after switching the system on, or
By pressing the <Del> key or by simultaneously pressing <CTRL>, <ALT>, and <ESC> keys when the following message appears briefly at the bottom of the screen during POST:
If the message disappears before you respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the RESET button on the system case. You may also restart by simultaneously pressing <CTRL>, <ALT>, and <Delete> keys. If you do not press the keys at the correct time and the system does not boot, an error message appears and you are again asked to
Press DEL to enter SETUP
Press F1 to continue, DEL to enter SETUP

Getting Help
Press F1 and a small help window pops up that describes the appropriate keys to use and the possible selections for the highlighted item. To exit the Help Window press <Esc> or the F1 key again.
In Case of Problems
If, after making and saving system changes with Setup, you discover that your computer is no longer able to boot, the Award BIOS supports an override to the CMOS settings that resets your system to its default configuration.
You can invoke this override by immediately pressing <Insert> when you restart your computer. You can restart by either using the ON/OFF switch, the RESET button or by pressing <CTRL>, <ALT> and <Delete> at the same time.
The best advice is to only alter settings that you thoroughly understand. In particular, do not change settings in the Chipset screen without good reason. The Chipset defaults have been carefully chosen by PEP Modular Computers for optimum performance and reliability. Even a seemingly small change to the Chipset setup may result in the system becoming unstable.
Setup Variations
Not all systems have the same Setup. While the basic look and function of the Setup program remains the same for all systems, the appearance of your Setup screens may differ from the screens shown here. Each system design and chipset combination require customized configurations. In addition, the final appearance of the Setup program depends on your system designer. Your system designer may decide that certain items should not be available for user configuration and remove them from the Setup program.

The BIOS has the capability to automatically detect the specifications and optimal operating mode of almost all EIDE hard drives. When you select type AUTO for a hard drive, the BIOS detects its specifications during POST, every time the system boots.
If you do not want to select drive type AUTO, other methods of selecting the drive type are available as follows:
1. Match the specifications of your installed EIDE hard drive(s) with the pre-
programmed values for drive types 1 through 45.
2. Select USER and enter values into each drive parameter field.
3. Use the EIDE HDD AUTO DECTECTION function in “Setup”.
The following table provides a brief explanation of drive specifications:

Halt On
During the power-on self-test (POST), the computer stops if the BIOS detects a hardware error. You can program the BIOS to ignore certain errors during POST and continue the boot-up process. The possible selections are listed in the following table.
Memory
You cannot change any values in the Memory fields; they are only for your information. The fields show the total installed random access memory (RAM) and amounts allocated to base memory, extended memory, and other (high) memory. RAM is counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB: approximately one million bytes).
RAM is the computer's working memory, where the computer stores programs and data currently being used, so they are accessible to the CPU. Modern personal computers may contain up to 64 MB, 128 MB, or more.
Base Memory
Typically 640 KB. Also called conventional memory. The DOS operating system and conventional applications use this area.
Extended Memory
Above the 1 MB boundary. Early IBM personal computers could not use memory above 1 MB, but current PCs and their software can use extended memory.
Other Memory
Between 640 KB and 1 MB; often called High Memory. DOS may load terminate-and­stay-resident (TSR) programs, such as device drivers, in this area, to free as much conventional memory as possible for applications. Lines in your CONFIG.SYS file that start with LOADHIGH load programs into high memory.
Table 4-5: POST Specific Commands
Command POST Action
No errors POST does not stop for any errors. All errors If the BIOS detects any non-fatal error, POST
stops and prompts you to take corrective action.
All, But Keyboard POST does not stop for a keyboard error, but
stops for all other errors.
All, But Diskette POST does not stop for diskette drive errors,
but stops for all other errors.
All, But Disk/Key POST does not stop for a keyboard or disk
error, but stops for all other errors.

4.5 BIOS Features Setup
This screen contains industry-standard options additional to the core PC AT BIOS. This section describes all fields presented by Award Software in this screen. The example screen below may vary somewhat from the one in your Setup program; your system board designer may omit or modify some fields
Figure 4-3: BIOS Features Setup — Screen Display
CPU Internal Cache / External Cache
Cache memory is additional memory that is much faster than conventional DRAM (system memory). CPU’s from 486-type on up contain internal cache memory, and most, but not all, modern PC’s have additional (external) cache memory. When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU.
The External Cache field may not appear if your system does not have external cache memory.
CPU L2 Cache ECC Checking
When you select Enabled, memory checking is enabled when the external cache contains ECC SRAM’s.
Quick Power-on Self Test
Select Enabled to reduce the amount of time required to run the power-on self-test (POST). A quick POST skips certain steps. We recommend that you normally disable quick POST. Better to find a problem during POST than lose data during your work.

Boot from LAN first
If Your BIOS if capable of Booting from LAN via DHCP/BOOTP – protocol (option), you can switch this option on/off here.
Boot Sequence
The original IBM PC’s loaded the operating system from drive A (floppy disk), so IBM PC-compatible systems are designed to search for an operating system first on drive A, and then on drive C (HardDisk). However, modern computers usually load the operating system from the hard drive, and may even load it from a CD-ROM drive. The BIOS now offers 10 different boot sequence options of three drives each. In addition to the traditional drives A and C, options include EIDE hard drives D, E and F; plus an SCSI hard drive and a CD -ROM drive.
Swap Floppy Drive
This field is effective only in systems with two floppy drives. Selecting Enabled assigns physical drive B to logical drive A, and physical drive A to logical drive B.
Boot Up Floppy Seek
When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KB, 1.2 MB, and
1.44 MB capacity all have 80 tracks. Because very few modern PC’s have 40-track
floppy drives, we recommend that you set this field to Disabled to save time.
Boot Up Numlock Status
Toggle between On or Off to control the state of the NumLock key when the system boots. When toggled On, the numeric keypad generates numbers instead of controlling cursor operations.
Boot Up System Speed
Select High to boot at the default CPU speed; select Low to boot at the speed of the AT bus. Some add-in peripherals or old software (such as old games) may require a slow CPU speed. The default setting is High.
Gate A20 Option
Gate A20 refers to the way the system addresses memory above 1 MB (extended memory). When set to Fast, the system chipset controls Gate A20. When set to Normal, a pin in the keyboard controller controls Gate A20. Setting Gate A20 to Fast improves system speed, particularly with OS/2 and Windows.
Typematic Rate Setting
When Disabled, the following two items (Typematic Rate and Typematic Delay) are irrelevant. Keystrokes repeat at a rate determined by the keyboard controller in your system.
When Enabled, you can select a typematic rate and typematic delay.

Typematic Rate (Chars/Sec)
When the typematic rate setting is enabled, you can select a typematic rate (the rate at which a character repeats when you hold down a key) of 6, 8, 10, 12, 15, 20, 24 or 30 characters per second.
Typematic Delay (ms)
When the typematic rate setting is enabled, you can select a typematic delay (the delay before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.
Security Option
If you have set a password, select whether the password is required every time the System boots, or only when you enter Setup.
PS/2 Mouse Function Control
If your system has a PS/2 mouse port and you instal a serial pointing device, select Disabled.
PCI/VGA Palette Snoop
Your BIOS Setup may not contain this field. If the field is present, leave at Disabled.
OS Select for DRAM>64MB
Select OS2 only if you are running the OS/2 operating system with greater than 64 MB of RAM in your system.
Report No FDD for WIN 95
Select Yes to release IRQ6 when the system contains no floppy drive, for compatibility with Windows 95 logo certification. In the Integrated Peripherals screen, select
Disabled for the Onboard FDC Controller field. Shadow
Software that resides in a read-only memory (ROM) chip on a device is called firmware. The Award BIOS permits shadowing of firmware such as the system BIOS, video BIOS, and similar operating instructions that come with some expansion peripherals, such as, for example, a SCSI adaptor.
Shadowing copies firmware from ROM into system RAM, where the CPU can read it through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by the system through the 8-bit X-bus. Shadowing improves the performance of the system BIOS and similar ROM firmware for expansion peripherals, but it also reduces the amount of high memory (640 KB to 1 MB) available for loading device drivers, etc.
Enable shadowing into each section of memory separately. Many system designers hardwire shadowing of the system BIOS and eliminate a System BIOS Shadow option.
Video BIOS shadows into memory area C0000-C7FFF. The remaining areas shown on the BIOS Features Setup screen may be occupied by other expansion card firmware. If an expansion peripheral in your system contains ROM-based firmware, you need to know the address range the ROM occupies to shadow it into the correct area of RAM.

Socket Window Page
The CP302 is equipped with a 32-pin socket to take additional Flash-ROM. This Flash­ROM may be addressed by a paging mechanism. The size of one Flash page can be set at this point as follows:
Award Preboot Agent
Agent software may be enabled and disabled. The default is Disabled.
Agent Port Address
Select which UART address Agent software should use. Note to have set a UART in the INTEGRATED PERIPHERALS page to one of the below allowed settings. Recommended is 03F8h, which means COM1 (03F8h / IRQ 4); “auto” must not be selected.
The Agent system must have a serial (RS-232C) peripheral subsystem, to support a null modem (direct) connection.
If the Agent and host connect, but a session is not established, check the Agent COM port settings which should read as follows:
3F8h - IRQ4 2F8h - IRQ3 3E8h - IRQ4 2E8h - IRQ3

Agent Host Drive A
When the administrative host is using the Preboot Manager application, the Agent can boot and run applications from host floppy drive A. INT13 calls intended for the Agent floppy drive A are redirected by the Agent extension to the host floppy drive A. All other INT13 calls are passed along to the original interrupt handler. The Manager application can receive the Agent drive A interrupt and interpret the commands. It then calls its own INT13 handler to read or write the requested sectors to host drive A. Both Manager and Agent serial version software use Xmodem protocol for all transfers.
The floppy drive redirection feature permits support personnel to remotely administer two vital tools on the Agent system:
PC DIAG diagnostics package from Unicore Software (available through Award Software as part of the Manager application).
AWDFLASH BIOS flash upgrade utility. (in batch mode, this means giving the parameters at the command line; e.g. awdflash <filename> /Sn/Py, DO NOT USE INTERACTIVE MODE!!!)
Select Enabled to enable this feature, default is Disabled.
Agent after Boot
In the "standard" Agent product, Agent software continues to function after the operating system loads. However, some non-DOS operating systems are not compatible with the Agent BIOS extension, so the Agent should disable when the OS loads. Selecting Disabled turns off the Agent software just as the BIOS transfers control to the operating system. Default is Disabled.
Award Baud Rate
Select the speed at which the UART is to operate. Default is 19200. When using the Preboot Manager on the host, always select 19200 baud.
Null-Modem Cable Pinout
Figure 4-4: Null-Modem Cable Connection
A null-modem cable is a serial cable designed to connect two PC’s. Each end has a 9-pin, female RS-232C connector. If you are creating your own 9-pin cable, connect the two ends through the cable as shown here.

4.6 Chipset Features Setup
This section describes features of the PIIX4 PCIset. If your system contains a different chipset, this section will bear little resemblance to what you see on your screen..
Advanced Options
The parameters in this screen are for system designers, service personnel, and technically competent users only. Do not reset these values unless you understand the consequences of your changes.
Figure 4-5: Chipset Features Setup — Screen Display.
SDRAM Control by Manual / Auto
Auto Configuration selects predetermined optimal values for chipset parameters. When Disabled, chipset parameters revert to setup information stored in the CMOS. Many fields in this screen are not available when Auto Configuration is Enabled.
SDRAM RAS To CAS Delay
Select the RAS to CAS delay time. See Refresh Cycle Time for information about the Auto Configuration of this value.
PEP Advantage
This section describes all the fields presented on this screen display. Please note that your system board designer may omit or modify some of the fields described in the following.

SDRAM RAS Precharge Time
The precharge time is the number of cycles it takes for the RAS to accumulate its charge before DRAM refresh. If insufficient time is allowed, refresh may be incomplete and the DRAM may fail to retain data.
SDRAM CAS Latency Time
When synchronous DRAM is installed, you can control the number of CLK’s between the SDRAM’s sample of a read command and the time when the controller samples read data from the SDRAM’s. Do not reset this field from the default value specified by the system designer.
SDRAM Precharge Control
When Enabled, all CPU cycles to SDRAM result in an All Banks Precharge Command on the SDRAM interface.
DRAM Data Integrity Mode
Select Non-ECC or ECC (error-correcting code), according to the type of installed DRAM.
System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at 0xF0000 to 0xFFFFF, resulting in better system performance. However, if any program writes to this memory area, a memory access error may result.
Video BIOS Cacheable
Selecting Enabled allows caching of the video BIOS ROM at 0xC0000 to 0xC7FFF, resulting in better video performance. However, if any program writes to this memory area, a memory access error may result.
Video RAM Cacheable
Selecting Enabled allows caching of the video memory (RAM) at 0xA0000 to 0xAFFFF, resulting in better video performance. However, if any program writes to this memory area, a memory access error may result.
8/16-bit I/O Recovery Time
The I/O recovery mechanism adds bus clock cycles between PCI-originated I/O cycles to the ISA bus. This delay takes place because the PCI bus is so much faster than the ISA bus.
These two fields let you add recovery time (in bus clock cycles) for 16-bit and 8-bit I/O.
Memory Hole at 15M-16M
You can reserve this area of system memory for ISA adaptor ROM. When this area is reserved, it cannot be cached. The user information for peripherals that need to use this area of system memory usually discusses their memory requirements.

Passive Release
When Enabled, CPU to PCI bus accesses are allowed during passive release. Otherwise, the arbiter only accepts another PCI master access to local DRAM.
Delayed Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select Enabled to support compliance with PCI specification version 2.1.
AGP Aperture Size (MB)
Select the size of the Accelerated Graphics Port (AGP) aperture. The aperture is a portion of the PCI memory address range dedicated for graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any translation. See http://www.agpforum.org for AGP information.
CPU Warning Temperature
Select the combination of lower and upper limits for CPU temperature, if your computer contains an environmental monitoring system. If the CPU temperature extends beyond either limit, any warning mechanism programmed into your application is activated.
Current CPU Temperature
This field displays the current CPU temperature, if your computer contains an environmental monitoring system.
Current CPU Fan 1
Monitors the onboard Fan mounted on the CPU heat sink, if available.
Current CPU Fan 2
Monitors the Fan signal routed to the Rear I/O connector.
Voltage Monitor
Displays all onboard voltages for diagnostic purposes.
Shutdown Temperature
Select the combination of lower and upper limits for the system shutdown temperature, if your computer contains an environmental monitoring system. If the temperature extends beyond either limit, the system shuts down.
Recommendation for optimizing performance: With only 64/128 MB onboard SDRAM is installed, use the following settings: SDRAM RAS-to-CAS Delay: 2 SDRAM RAS Precharge Time: 2 SDRAM CAS latency Time: 2 If additional RAM is installed in the SODIMM socket, automatic SDRAM Control is
recommended. Field Shutdown Temperature: this does not exist for the CP302
