HP/Phoenix BIOS Description
The System ROM contains the system BIOS (including the boot code, the
ISA and PCI initialization, DMI, the Setup program and the Power-On Self-
Test routines, plus their error messages).
The PC uses 128 KB of 200ns, Flash EEPROM implemented within a single
256 K ✕ 8-bit ROM chip. This is a ROM that can be returned to its
unprogrammed state, by the application of appropriate electrical signals to
its pins, and then reprogrammed with the latest upgrade firmware.
Updating the System ROM
The System ROM can be updated with the latest BIOS firmware. It can be
ordered from HP or downloaded from one of the HP online services.
The System ROM is updated by running the PHLASH utility, PHLASH.EXE ,
which is supplied with the BIOS upgrade file, NN07xx.FUL , and the system
definition file, platform.bin . You must specify the model number of the
PC since the utility which is supplied for a different model cannot be used
with this one. It must be run from a diskette.
