Reprogramming the BIOS with the crisis recovery jumper If the BIOS becomes corrupted, use the crisis recovery jumper to reprogram the BIOS. You will also need a USB floppy drive and the HP crisis recovery floppy disk. The crisis recovery jumper is on jumper block P56 on the system board. Refer to the HP ProLiant DL185 Generation 5 Server Maintenance and Service Guide for the location of this jumper block and the crisis recovery setting. To reprogram the BIOS: 1. Perform the pre-installation procedures described on page 58. 2. If necessary, remove any expansion boards, assemblies, or cables that prevent access to the crisis recovery jumper block. 3. Connect a USB floppy drive to one of the USB ports on the server. 4. Insert the HP crisis recovery floppy disk into the floppy drive. 5. Locate the crisis recovery jumper (P56) on the system board. By default, the jumper is installed in the park position on the left and middle pins (as viewed from the front of the server). 6. Set the jumper over the middle and right pins to enable the boot block, which forces the server to boot from the floppy drive. 7. If the DIMM1 and DIMM2 memory slots are empty, move the installed memory in slots DIMM3 and DIMM4 to slots DIMM1 and DIMM2. 8. Perform all of the post-installation procedures described on page 59 except for step 4; do not reinstall the top cover of the server. 9. When the server begins reading the floppy disk, reinstall the crisis recovery jumper over the left and middle pins. The system reprograms the BIOS from the floppy disk and then reboots normally with the reprogrammed BIOS. 10. If you did not move memory modules in step 7, perform step 4 of the post-installation procedures described on page 59 to reinstall the top cover of the server. If you did move memory modules in step 7, move the memory modules back to their original locations: a. Perform the pre-installation procedures described on page 58. b. Move the memory modules installed in slots DIMM1 and DIMM2 to their original locations in slots DIMM3 and DIMM4. c. Perform the post-installation procedures described on page 59.

System BIOS configuration 39
Reprogramming the BIOS with the crisis recovery
jumper
If the BIOS becomes corrupted, use the crisis recovery jumper to reprogram the BIOS. You will also
need a USB floppy drive and the HP crisis recovery floppy disk. The crisis recovery jumper is on
jumper block P56 on the system board. Refer to the
HP ProLiant DL185 Generation 5 Server
Maintenance and Service Guide
for the location of this jumper block and the crisis recovery setting.
To reprogram the BIOS:
1.
Perform the pre-installation procedures described on page 58.
2.
If necessary, remove any expansion boards, assemblies, or cables that prevent access to the
crisis recovery jumper block.
3.
Connect a USB floppy drive to one of the USB ports on the server.
4.
Insert the HP crisis recovery floppy disk into the floppy drive.
5.
Locate the crisis recovery jumper (P56) on the system board.
By default, the jumper is installed in the park position on the left and middle pins (as viewed
from the front of the server).
6.
Set the jumper over the middle and right pins to enable the boot block, which forces the server to
boot from the floppy drive.
7.
If the DIMM1 and DIMM2 memory slots are empty, move the installed memory in slots DIMM3
and DIMM4 to slots DIMM1 and DIMM2.
8.
Perform all of the post-installation procedures described on page 59 except for step 4; do not
reinstall the top cover of the server.
9.
When the server begins reading the floppy disk, reinstall the crisis recovery jumper over the left
and middle pins. The system reprograms the BIOS from the floppy disk and then reboots
normally with the reprogrammed BIOS.
10.
If you did not move memory modules in step 7, perform step 4 of the post-installation procedures
described on page 59 to reinstall the top cover of the server. If you did move memory modules
in step 7, move the memory modules back to their original locations:
a.
Perform the pre-installation procedures described on page 58.
b.
Move the memory modules installed in slots DIMM1 and DIMM2 to their original locations in
slots DIMM3 and DIMM4.
c.
Perform the post-installation procedures described on page 59.
