Software and Firmware
Software and Firmware
The System ROM consists of a 256 KB flash programmable EEPROM.
Updates can be obtained from the HP Bulletin Board System (BBS) and can
be loaded (flashed) using the HP6Init program (
). This
HP6Init.EXE
program should be run from a bootable floppy disk.
The System ROM contains the following:
• power-on self-test (POST)
• Setup program
• BIOS
• security support.
Also mentioned here, though not implemented on the System ROM, are the
video BIOS, operating system drivers, and diagnostic utilities.
POST
When the PC is started, the initial "Vectra" screen, as shown below, is
displayed. Under normal circumstances, the power-on self-test (POST, also
referred to as the HP System Hardware Test) does not show its results on
the screen. POST will even run successfully in the absence of a keyboard, and
test the rest of the system.
