INSTALLING HARDWARE PXE BIOS SUPPORT
3-60
Limitations
BIOS Console redirection terminates after an operating
system has being loaded. The operating system is
responsible for continuing console redirection after that.
BIOS console redirection is a text console. Graphical data,
such as a logo, are not redirected.
Interface to Server Management
If the BIOS determines that console redirection is enabled, it
will read the current baud rate and pass this value to the appro-
priate management controller via the Intelligent Platform Man-
agement Bus (IPMB).
PXE BIOS Support
The BIOS supports the EFI PXE implementation. To utilize this,
the user must load EFI Simple Network Protocol driver and the
UNDI driver specific for the network interface card being used.
The UNDI driver should be included with the network interface
card. The Simple Network Protocol driver can be obtained from
http://developer.intel.com/technology/framework.
The BIOS supports legacy PXE option ROMs in legacy mode
and includes the necessary PXE ROMs in the BIOS image for
the onboard controllers. The legacy PXE ROM is required to
boot a non-EFI operating system over the network.
Checkpoints
A checkpoint is either a byte or word value output to SuperIO
printer port. The BIOS outputs checkpoints throughout boot-
block and Power-On Self Test (POST) to indicate the task the
system is currently executing. Checkpoints are very useful in
