4.7.2 Password Clear Jumper
If the user or administrator password(s) is lost or forgotten, moving the password clear jumper
(board location J1H3) to the clear position will clear both passwords. The BIOS determines if
the password clear jumper is in the clear position during BIOS POST and clears any passwords
if present. The password clear jumper must be restored to its original position before a new
password(s) can be set.
4.8 Extensible Firmware Interface (EFI)
When EFI is selected as a boot option, the BIOS will support an EFI Specification 1.10
compliant environment. More details on EFI are available at
http://developer.intel.com/technology/efi/index.htm
4.8.1 EFI Shell
The EFI Shell is a special type of EFI application that allows EFI commands and other EFI
applications to be launched. The BIOS implements an EFI shell in flash and the shell can be
invoked from the BIOS provided EFI environment. The EFI shell provided in flash implements
all the commands specified in the EFI1.1ShellCommands.pdf document that comes with the
EFI sample implementation, revision 1.10.14.62 (available from
http://developer.intel.com/technology/efi/main_sample.htm
).
4.9 Operating System Boot, Sleep, and Wake
The IPMI 1.5 specification, chapter 22.10 and 22.11, has provisions for server management
devices to set certain boot parameters by setting boot flags. Among the boot flags, which are
parameter #5 in the IPMI specification, the BIOS checks data 1-3 for forced boot options.
The BIOS supports force boots from: PXE, HDD, FDD, and CD.
On each boot, the BIOS determines what changes to boot options have been set by invoking
the Get System Boot Options Command, takes appropriate action, and clears these settings.
