main memory
There is one 168-pin DIMM slot on the system board for installing main
memory. All HP e-pc models are supplied with a memory module of at least
64 MB non-ECC SDRAM. Only HP memory modules are supported. Memory
upgrades are not supported.
processors
The HP e-pc is equipped with either a single Socket 370 Intel Celeron or
socket 370 Intel Pentium III processor. Socket 370 is a conversion of Slot 1
(used previously by Celerons and Pentium Is) to a socket, running at the
same bus protocol as the Pentium II (the GTL+ bus protocol). The processor
is connected to the system board through a Plastic Pin Grid Array (PPGA)
370 Socket. The reduction in size achieved by the Socket 370 Celeron is due
to the integration of the L2 cache on the processor die. Like the Celeron
processor, the Pentium III comes in a 370-pin socket (PGA370) package.
To find out more about Socket 370 Celeron technology, refer to the Te ch n i ca l
Reference Manual - HP PC Technology.

graphic interface
The HP e-pc uses Intel® 810E integrated graphics with Direct AGP and
Dynamic Video Memory technology. The video memory is dynamically
allocated on system memory (SDRAM) by the chip set, and shared with main
memory.
Depending on the configuration and application, between 4 and 10MB of main
memory may be reserved for video.
Its architecture consists of dedicated multi-media engines executing in
parallel to deliver high performance 3D, 2D and motion compensation video
capabilities. The 3D and 2D engines are managed by a 3D/2D pipeline
preprocessor allowing a sustained flow of graphics data to be rendered and
displayed.

BIOS summary
BIOS summary
The HP e-pc contain an HP/AMI BIOS. The system ROM contains the POST
(power-on self-test) routines, and the BIOS: the System BIOS, video BIOS,
and 3Com LAN option ROM.
The system BIOS is identified by the version number IN.xx.yy. The latest
BIOS version for your HP e-pc and instructions for updating the BIOS can be
downloaded from the HP’s Support Web site at:
www.hp.com/go/e-pcsupport
This section covers:
• The BIOS Setup program
•Power saving
• BIOS addresses
• The order in which POST tests are performed
• Beep codes
using the HP setup program
Press F2 to run the Setup program, when the “HP” logo is displayed
immediately after restarting the HP e-pc.
Press F8 to enter the Boot menu. Use the boot menu to select the order of the
devices the HP e-pc will use to start (boot) from.
Press F12 to boot on LAN. This overrides the Boot Policy selected from the
HP Setup Screen.
Alternatively, press Esc to view the summary configuration screen. The
summary configuration screen will remain on the screen until a key is
pressed. A summary screen will also be displayed at the end of POST.
The Setup screen has only one menu.
auto-detection and auto-configuration
Auto-detection and auto-configuration are essential to the ease of use
concept. The HP BIOS avoids users having to enter Setup by automating
many of the selection procedures:
• Conflict detection and resolution of system board, PCI, and PnP devices
and their resources.
• Auto-configuration and optimization of chip set based on bus speeds

• IDE HDD auto-detection, including support for IDE drives > 8.4GB
• ATAPI CD-ROM auto-detection
• PS/2 Mouse and Keyboard detection
NOTE A USB floppy is installed as a standard drive by the BIOS (drive A: or E:). A
USB floppy is installed as drive A: (for Windows 2000) or drive E: (Windows
98), depending on the number of external drives attached.

The menu items contained in this page are largely security features. The
purpose of this page is to facilitate the prevention of Unauthorized users from
using or booting from selected drives and network connections for example:
• Boot Policy: Allows you to select the devices and the order of the devices
from which the BIOS attempts to boot the operating system. During POST,
if the BIOS is unsuccessful at booting from one device, it will then try the
next one on the list until an operating system is found.
• F12 Hot Key to Boot On LAN: Allows the user to enable or disable this
feature.
• CD-ROM, Integrated Audio Interface, Integrated USB Interface, Serial
Port and Parallel Port: These menu items enable you to unlock/lock these
integrated Data Communications Ports
• Supervisor Password. This password prevents unauthorized access to the

Soft Power Down is available with the Windows NT operating system. If users
want to shut down their HP e-pc, they are able to do so directly from the

the HP e-pc.
The hardware to do this is contained in the ICH chipset. This chipset is
described in detail in Technical Reference Manual - HP PC Technology.

to shut down the operating system when an application is open and has not
been saved, they are requested to save their work before the computer can be
powered off.
NOTE Safe Off is integrated in Windows 98 and Windows 2000.
The hardware to do this is contained in the ICH chipset. This chipset is
described in detail in Technical Reference Manual - HP PC Technology.

hp I/O port map (I/O addresses used by the system)
Peripheral devices, accessory devices and system controllers are accessed via
the system I/O space, which is not located in system memory space. The 64
KB of addressable I/O space comprises 8-bit and 16-bit registers (called
I/O ports) located in the various system components.

Although the Setup program can be used to change some of the settings, the
following address map is not completely BIOS dependent, but is determined
partly by the operating system. Note that some of the I/O addresses are
allocated dynamically.

DMA channel controllers
Only “I/O-to-memory” and “memory-to-I/O” transfers are allowed.
“I/O-to-I/O” and “memory-to-memory” transfers are disallowed by the
hardware configuration.
The system controller supports seven DMA channels, each with a page
register used to extend the addressing range of the channel to 16 MB. The
following table summarizes how the DMA channels are allocated.

order in which the POST tests are performed
order in which the POST tests are performed
Each time the system is powered on, or a reset is performed, the POST is
executed. The POST process verifies the basic functionality of the system
components and initializes certain system parameters.
The POST starts by displaying a graphic screen of the Hewlett-Packard logo
when the HP e-pc is started.
Devices, such as memory and newly installed hard disk drives, are configured
automatically. The user is not requested to confirm the change. Newly
removed hard disks are detected, and the user is prompted to confirm the
new configuration by pressing F4. Note, though, that the POST does not
detect when a hard disk drive has been otherwise changed.
During the POST, the BIOS and other ROM data is copied into high-speed
shadow RAM. The shadow RAM is addressed at the same physical location as
the original ROM in a manner which is completely transparent to applications.
It therefore appears to behave as very fast ROM. This technique provides
faster access to the system BIOS firmware.
The following table lists the POST checkpoint codes written at the start of
each test.
uncompressed INIT code checkpoints
01 NMI is Disabled. CPU ID saved.Init code Checksum verification starting.
02 To do DMA init, Keyboard controller BAT test, start memory refresh
and going to 4GB flat mode.
D3 To start Memory sizing.
D4 To comeback to real mode. Execute OEM patch. Set stack.
D5 E000 ROM enabled. Init code is copied to segment 0 and control to be
transfered to segment 0.
D6 Control is in segment 0. To check <CTRL><HOME> key and verify main BIOS checksum.
If either <CTRL><HOME> is pressed or main BIOS checksum is bad, go to check point E0
else goto check point D7.
D7 To pass control to Interface Module.
