Interface to Server Management (Optional)

If the BIOS determines that console redirection is enabled, it will read the current baud
rate and pass this value to the appropriate management controller via the Intelligent Plat-
form Management Bus (IPMB).

Network BIOS Support

PXE Boot

The BIOS supports the EFI PXE implementation. To utilize this, the user must load EFI Sim-
ple 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 Sim-
ple Network Protocol driver can be obtained from
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 Debug port. The BIOS outputs check-
points throughout bootblock and Power-On Self Test (POST) to indicate the task the sys-
tem is currently executing. Checkpoints are very useful in aiding software developers or
technicians in debugging problems that occur during the pre-boot process.
Checkpoints can be defined as follow:
Standard Checkpoint

ACPI/ASL Checkpoint

OEM-Reserved Checkpoint

MRC POST Code Checkpoints


Debug Header

Windmill has one debug header placed in front of the motherboard. Debug card can be
plugged in vertically and forward facing. The debug head support functions:
Support Hot-Plug

Provide RS232 serial port connector, for use of console redirection

Two 7-segment LED displays
