[2.3.209]
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

.
[2.3.210]
The BIOS supports legacy PXE option ROMs in leg-
acy 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.

[2.3.212] Checkpoints
[2.3.213]
A checkpoint is either a byte or word value output to
Debug 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
aiding software developers or technicians in debugging prob-
lems that occur during the pre-boot process.
