Preparation for use and operation Configuring the server and components
Recovery Boot:
This switch controls whether the system attempts to boot using the BIOS code
stored in flash memory, or, if the BIOS code is corrupt, whether a recovery boot
is performed by loading the BIOS code from a floppy disk into flash memory.
If you want to start a recovery boot, proceed as follows:
Ê Follow the procedure described in the section “Changing the switch
settings”.
Ê Set DIP switch 2 (see table 2 on page 38) to ON.
Ê Insert the flash memory update floppy disk in drive A.
Ê Turn on the system.
After the system boots, a single beep is emitted and the recovery process is
started. This takes about three minutes. Once the recovery process has
been completed, two beeps are emitted.
During recovery, there is no screen display on the monitor and the keyboard
is disabled.
The following beep sequences indicate the recovery status:
Ê Shut down the system, turn off the server and disconnect it from the line
voltage.
Ê Set DIP switch 2 (see table 2 on page 38) to OFF.
Ê Remove the floppy disk from drive A.
Ê Reconnect all the peripheral devices, reconnect the server to the line voltage
and switch it on.
Ê Run BIOS Setup to enter a new password (see the section “BIOS Setup” on
page 47).
