4 Summary of the HP/Phoenix BIOS
HP/Phoenix BIOS (BIOS version: GX.07.xx)
To see the tests performed during the POST, press when the initial HP “Vectra” logo appears, and the display will switch to text mode. In this mode, a summary configuration screen will be displayed at the end of the POST.
Devices, such as memory and hard disks, are configured automatically. The user is not requested to confirm the change. However, the user is prompted if a device is found to have gone missing since the previous boot. The user can simply accept the new configuration by pressing .
During the POST, the BIOS and other ROM data are copied into
The table on the following page lists the POST routines in the order in which they are executed (from the shadow RAM). If the POST is initiated by a soft
reset and , the RAM tests are not executed and shadow RAM is not cleared. In all other respects, the POST executes in the same way following
