Procedure 2: Use BIOS Recovery Header and bios.cap Recovery File
Step 1
Download the BIOS update package and extract it to a temporary location.
Step 2
Copy the contents of the extracted recovery folder to the root directory of a USB drive. The recovery folder contains
the bios.cap file that is required in this procedure.
The bios.cap file must be in the root directory of the USB drive. Do not rename this file. The USB drive must
be formatted with either the FAT16 or FAT32 file system.
Note
Step 3
Shut down and remove power from the server as described in
Shutting Down and Removing Power From the Server,
. Disconnect power cords from all power supplies.
Step 4
Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach
cables from the rear panel to provide clearance.
If you cannot safely view and access the component, remove the server from the rack.
Caution
Step 5
Remove the top cover from the server as described in
Removing the Server Top Cover, on page 28
.
Step 6
Locate header block J38 and pins 11-12, as shown in
Service Headers and Jumpers, on page 78
.
Step 7
Install a two-pin jumper across pins 11 and 12.
Step 8
Reconnect AC power cords to the server. The server powers up to standby power mode.
Step 9
Insert the USB thumb drive that you prepared in Step 2 into a USB port on the server.
Step 10
Return the server to main power mode by pressing the Power button on the front panel.
The server boots with the updated BIOS boot block. When the BIOS detects a valid bios.cap file on the USB drive, it
displays this message:
Found a valid recovery file...Transferring to Cisco IMC
System would flash the BIOS image now...
System would restart with recovered image after a few seconds...
Step 11
Wait for server to complete the BIOS update, and then remove the USB drive from the server.
During the BIOS update, Cisco IMC shuts down the server and the screen goes blank for about 10 minutes.
Do not unplug the power cords during this update. Cisco IMC powers on the server after the update is complete.
Note
Step 12
After the server has fully booted, power off the server again and disconnect all power cords.
Step 13
Remove the jumper that you installed.
If you do not remove the jumper, after recovery completion you see the prompt, “Please remove the recovery
jumper.”
Note
Step 14
Replace the top cover, replace the server in the rack, replace power cords and any other cables, and then power on the
server by pressing the Power button.
