Rom Flashing; Upgrading - HP dx7300 Technical Reference Manual

BIOS ROM

8.2 ROM Flashing

The system BIOS firmware is contained in a flash ROM device that can be re-written with new
BIOS code using a flash utility locally (with F10 setup), with the HPQFlash program in a
Windows environment, or with the FLASHBIN.EXE utility in a DOS or DOS-like environment.

8.2.1 Upgrading

Upgrading the BIOS is not normally required but may be necessary if changes are made to the
unit's operating system, hard drive, or processor. All BIOS ROM upgrades are available directly
from HP. Flashing is done either locally thrugh F10 setup, the HPQFlash program in a Windows
environment, or with the FLASHBIN.EXE utility in a DOS or DOS-like environment. Flashing
may also be done by deploying either HPQFlash or FLASHBIN.EXE through the network boot
function.
This system includes 64 KB of write-protected boot block ROM that provides a way to recover
from a failed flashing of the system BIOS ROM. If the BIOS ROM fails the flash check, the boot
block code provides the minimum amount of support necessary to allow booting the system from
the diskette drive and re-flashing the system ROM with a CD, USB, or diskette.
