BIOS Recovery Mode
The BIOS Recovery Mode permits re-ashing the BIOS when the ash ROM has been corrupted.
The usual sequence of events for automatic recovery is:
1. Request recovery media by repeating a low-tone beep with POST code.
2. Insert recovery media and reset the system.
3. One beep indicates recovery media valid, and ash update started.
4. Approximately two minutes later, two beeps indicate ash update complete.
5. System automatically resets and starts the new BIOS.
The BIOS Recovery Mode, when using an LS240, is initiated using the following procedure:
1. Prior to attempting recovery for the rst time, either use a previously formatted unused or a
blank LS-240 diskette.
2. Unzip the recovery image and copy the S870BN4A.REC le (S870BN4B.REC for Madison) onto
the LS-240 diskette. The le S870BN4A.rec should be the only le on the disk.
3. With the system switched off and AC power disconnected:
a. Place I/O riser toggle switch #1 to the ON position (S8A1) for forced BIOS recovery. For
toggle switch location, refer to “I/O Riser Card Settings..
b. Insert diskette in LS-240 drive.
c. Reconnect the AC power and switch server power on.
d. LS-240 diskette activity started.
e. One full beep (start load S870BN4A.REC from disk to memory).
f. Wait two minutes. No indication of LS-240 activity will be seen until two beeps are heard
that indicate the BIOS recovery has completed successfully.
g. Remove the LS-240 recovery diskette, switch system power off, and disconnect AC power.
h. Replace the I/O toggle switch #1 to the OFF position, reconnect AC power and switch the
system on per updated BIOS release notes (i.e. clear CMOS first time booting).
The BIOS Recovery Mode, when using a CD, is initiated using the following procedure:
1. Unzip the recovery image and burn the included .iso le to a blank CD. The le S870BN4A.rec
should be the only le on the disk.
2. With the system switched off and AC power disconnected:
a. Place I/O riser toggle switch #1 to the ON position (S8A1) for forced BIOS recovery. For
toggle switch location, refer to “I/O Riser Card Settings”.
b. Reconnect the AC power and switch server power on.
c. Quickly insert CD into DVD drive
d. LS-240 diskette activity should start.
e. There should be one full beep (start load SR870BN4A.REC from disk to memory).
f. Wait two minutes. No indication of LS-240 activity will be seen until two beeps are heard
that indicate the BIOS recovery has completed successfully.
g. Remove the LS-240 recovery diskette, switch system power off, and disconnect AC power.
Replace the I/O toggle switch #1 to the OFF position, reconnect AC power and switch the system
on per updated BIOS release notes (i.e., clear CMOS rst-time booting).
