Recovering the BIOS
If you encounter a problem while you are updating the BIOS, such as a power outage, the BIOS
update may not be successful. If the system continues to try to boot from the new, corrupted
BIOS, you can manually recover the old BIOS so you can try another update.
To recover the old BIOS:
1
Insert a diskette (if a diskette drive is available), CD or DVD, or a bootable USB “disk-on-key”
containing the AMIBOOT.ROM file.
2
Turn on or restart the server. Press and hold C
TRL
+H
OME
during power up until the recovery
process begins (the server beeps). The process is complete when you see a message on
the screen.
3
Remove the diskette, the CD or DVD, or the bootable USB “disk-on-key.”
4
Restart the server. The old BIOS is recovered.
To manually recover the BIOS:
1
Turn off the server, then disconnect the power cords and all other cables connected to
the server.
2
Follow the instructions in “Opening the server case” on page 25 .
3
Remove the jumper across pins 1-2 of header J56-E, then place the jumper across pins 2-3.
4
Follow the instructions in “Closing the server case” on page 27 .
5
Insert a bootable USB “disk-on-key” containing a valid BIOS image into a USB port.
6
Reconnect the power cords and turn on the server. The BIOS recovery is initiated.
7
Wait until the BIOS recovery is completed. The process may take up to 5 minutes.
8
Remove the bootable USB “disk-on-key.”
9
Turn off the server, then disconnect the power cords and all other cables connected to
the server.
10
Follow the instructions in “Opening the server case” on page 25 .
11
Place the jumper back onto pins 1-2.
Important
This method does not work if the keyboard is connected through the KVM switch.
Caution
Moving the jumper while the power is on can damage your server. Always
turn off the server and unplug the power cords and all other cables before changing
the jumper.
