5 BIOS recovery mode. When this switch is set to On, perform
BIOS recovery using the boot block (boot block recovery).
The recovery boot block is in a protected area of flash memory
that cannot be overwritten. When the BIOS becomes corrupted
(for example, if a power failure occurs during a flash update), the
recovery boot block can be used to restore the BIOS. The code in
the recovery boot block enables the server to start up and read a
flash diskette. The flash utility automatically recovers the system
BIOS from the BIOS recovery files on the diskette. When the
flash is complete, the switch must be moved to the Off position.
The default setting is Off (disabled).
6 Ethernet operation mode. When this switch is set to On, the
onboard Ethernet controller is disabled. When this switch is set
to Off, the onboard Ethernet controller operates normally.
The default setting is Off.
7 Administrator password locked. When this switch is set to On,
the administrator password is unlocked, and may be changed or
reset although enhanced security is enabled. When this switch is
set to Off, the administrator password is locked, and may not be
changed or reset if enhanced security is enabled.
The default setting is Off.
