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.
