10.6 Wired For Management
Wired for Management (WFM) is an industry-wide initiative to increase overall manageability
and reduce total cost of ownership by allowing a server to be managed over a network. To meet
WFM requirements, the system BIOS supports the System Management BIOS Reference
Specification.
10.6.1 PXE BIOS Support
The BIOS will support EFI PXE implementation with the Universal Network Device Interface
driver included on the network card. The BIOS will also support legacy PXE option ROMs in
legacy mode. The legacy PXE ROM is required to boot a non-EFI Operating System over the
network.
10.7 System Management BIOS
There are two access methods defined for the System Management BIOS (SMBIOS) structures.
The Intel
® Server Board Set SE8500HW4 BIOS supports the table access method, where
accessing SMBIOS structures can be accessed under 32-bit protected-mode operating
systems. The PnP function interface is not supported by the Intel
® Server Board Set
SE8500HW4 BIOS.
The total number of structures can be obtained from the SMBIOS entry-point structure. The
system information is presented to an application as a set of structures that are obtained by
traversing the SMBIOS structure table referenced by the SMBIOS entry-point structure. Please
refer to the System Management BIOS Reference for more information.
10.8 Security
The Intel
®
Server Board Set SE8500HW4 BIOS can use two different levels of password
security to prevent unauthorized use of the system. Setting a user password allows for
modification of only the time, date, language and the user password. Setting an administrator
password allows full access to all setup fields. An administrator password should be set and
saved, before a user password can be set. The maximum length of the password can have up
to seven alphanumeric characters (a-z, A-Z, 0-9) and is not case sensitive.
Once set, a password can be cleared by changing it to an empty value. If only one password is
set, this password is required to enter the BIOS Setup.
If the administrator password is cleared, the user password will also be cleared. Passwords are
not enabled until the next reboot.
If the user enters three consecutive wrong passwords during the boot sequence, the system will
be placed into a halt state. A system reset is required to exit out of the halt state. This feature
makes it difficult to break the password by “trial and error” method.
If the user or administrator password(s) are lost, both passwords may be cleared by moving the
password clear jumper into the “clear” position. The BIOS determines if the password clear
jumper is in the “clear” position during the BIOS POST and, if required, clears both passwords.
The password clear jumper must be restored to its original position before a new password(s)
can be set.
