BIOS ROM Table 8-2 Setup Utility Heading Option Description Advanced* (continued) *For advanced users only Device options Allows you to set: • Printer mode (bi-directional, EPP & ECP, output only). • Num Lock state at power-on (off/on). • S5 Wake on LAN (enable/disable). • To disable Wake on LAN during the off state (S5), use the arrow (left and right) keys to select the Advanced > Device Options menu and set the S5 Wake on Lan feature to "Disable." This obtains the lowest power consumption available on the computer during S5. It does not affect the ability of the computer to Wake on LAN from suspend or hibernation, but will prevent it from waking from S5 via the network. It does not affect operation of the network connection while the computer is on. • If a network connection is not required, completely disable the network controller (NIC) by using the arrow (left and right) keys to select the Security > Device Security menu. Set the Network Controller option to "Device Hidden." This prevents the network controller from being used by the operating system and reduces the power used by the computer in S5. • Processor cache (enable/disable). • Unique Sleep State Blink Patterns. Allows you to choose an LED blink pattern that uniquely identifies each sleep state. • Integrated Video (enable/disable) Allows you to use integrated video and PCI Up Solution video at the same time (available on select models only). ✎ Inserting a PCI or PCI Express video card automatically disables Integrated Video. When PCI Express video is on, Integrated Video must remain disabled. • Monitor Tracking (enable/disable). Allows ROM to save monitor asset information. Allows you to set: • NIC PXE Option ROM Download (enable/disable). The BIOS contains an embedded NIC option ROM to allow the unit to boot through the network to a PXE server. This is typically used to download a corporate image to a hard drive. The NIC option ROM takes up memory space below 1MB commonly referred to as DOS Compatibility Hole (DCH) space. This space is limited. This F10 option will allow users to disable the downloading of this embedded NIC option ROM thus giving more DCH space for additional PCI cards which may need option ROM space. The default will be to have the NIC option ROM enabled. PCI VGA Configuration Displayed only if there are multiple PCI video adapters in the system. Allows you to specify which VGA controller will be the "boot" or primary VGA controller. ✎ Support for specific Computer Setup options may vary depending on the hardware configuration. 8-14 www.hp.com Technical Reference Guide

state at power-on (off/on).

• S5 Wake on LAN (enable/disable).

•

To disable Wake on LAN during the off state (S5), use the arrow

(left and right) keys to select the

Advanced

Device Options

menu and set the S5 Wake on Lan feature to “Disable.” This

obtains the lowest power consumption available on the computer

during S5. It does not affect the ability of the computer to Wake on

LAN from suspend or hibernation, but will prevent it from waking

from S5 via the network. It does not affect operation of the network

connection while the computer is on.

•

If a network connection is not required, completely disable the

network controller (NIC) by using the arrow (left and right) keys to

select the

Device Security

menu. Set the Network

Controller option to “Device Hidden.” This prevents the network

controller from being used by the operating system and reduces the

power used by the computer in S5.

• Processor cache (enable/disable).

• Unique Sleep State Blink Patterns. Allows you to choose an LED

blink pattern that uniquely identifies each sleep state.

• Integrated Video (enable/disable) Allows you to use integrated

video and PCI Up Solution video at the same time (available on

select models only).

✎

Inserting a PCI or PCI Express video card automatically disables

Integrated Video. When PCI Express video is on, Integrated

Video must remain disabled.

• Monitor Tracking (enable/disable). Allows ROM to save

monitor asset information.

Allows you to set:

• NIC PXE Option ROM Download (enable/disable). The BIOS

contains an embedded NIC option ROM to allow the unit to

boot through the network to a PXE server. This is typically used

to download a corporate image to a hard drive. The NIC

option ROM takes up memory space below 1MB commonly

referred to as DOS Compatibility Hole (DCH) space. This space

is limited. This F10 option will allow users to disable the

downloading of this embedded NIC option ROM thus giving

more DCH space for additional PCI cards which may need

option ROM space. The default will be to have the NIC option

ROM enabled.

PCI VGA

Displayed only if there are multiple PCI video adapters in the

system. Allows you to specify which VGA controller will be the

“boot” or primary VGA controller.
