Installing BIOS Software
This appendix explains how to reflash the system BIOS in the HP VXI
Pentium Controller from the controller’s floppy disk drive. This process is
rarely done only when the BIOS stored in the controller’s flash memory has
been damaged or when HP releases a new version of the BIOS to correct a
specific problem or to add support for new system features.
Note
The special BIOS boot diskette referred to in the instructions below is not
shipped with your HP VXI Pentium Controller. If required, it must be
obtained from an HP Support Representative.
Caution
It is strongly recommended that a trained computer service
technician performs the installation and removal of the jumpers
referred to in the instructions below. An HP Service Technician
can perform this task for you. Contact your HP Service and
Support Center for assistance.
Overview
The HP VXI Pentium Controller’s System BIOS is updated by using a
special boot diskette that contains the System BIOS image as well as the
code to perform the update.
To enable the recovery process and to allow writing to the flash memory
which contains the BIOS, two jumpers must be installed on jumper-pin
connector blocks located inside the controller. To access the jumper-pin
connector blocks, the controller must be powered down and removed from
the VXI mainframe in order to remove the side cover panel.
Once the jumpers have been installed and the controller returned to the VXI
mainframe, the system must be booted with the special BIOS boot diskette
loaded in the floppy disk drive. The recovery process will then automatically
update the BIOS.
Once the recovery process is complete, the controller must be powered down
and the jumpers removed before you can return to normal operation.
