In this way, the administrator can control HP Business Desktop computer configurations throughout - Compaq dc7100 | HP Business Desktop BIOS - Page 5
, information inquiries, or remote ROM updates when the computers are not being used. The HP BIOS enables the computer to respond quickly to a power resume and/or wake from low power states such as Suspend to RAM (S3) and power off. An HP Business Desktop computer responding to a remote wakeup event - Compaq dc7100 | HP Business Desktop BIOS - Page 6
Business Desktop computer systems can continue to respond to remote wakeup LAN messages once power has been restored. Multilanguage support The HP BIOS computer setup utility, F10 Setup, provides robust localization support for global enterprise computing (see the Computer Setup (F10) Utility Guide - Compaq dc7100 | HP Business Desktop BIOS - Page 7
30 to 60 days prior to the update for all the computers affected. This allows customers to plan for any impending BIOS changes.

computer motherboard may have to be replaced because the computer may not be able to restart. The HP BIOS uses hardware mechanisms on most HP Business Desktops to prevent access to the BIOS flash memory by any software other than the BIOS. This hardware traps any attempts to update the flash memory - Compaq dc7100 | HP Business Desktop BIOS - Page 11
be lost. As a convenience to the user, the DriveLock password and power-on passwords (or smart card credentials) can be set to match. In this case, the BIOS will use the Power-on password or smart card credential to unlock the drive for the user without additional prompts. For the sake of security - Compaq dc7100 | HP Business Desktop BIOS - Page 12
hardware The BIOS provides control with two types of physical security: hood latch and hood sensor. The hood latch is an electronically controlled mechanism that locks the chassis hood. The hood sensor is a device that detects if the chassis hood has been opened or removed. The administrator - Compaq dc7100 | HP Business Desktop BIOS - Page 13
