1.4.23PXE Words (Words 30h - 3Eh)

Words 30h through 3Eh (bytes 60h through 7Dh) have been reserved for configuration and version values to be used by PXE code.

1.4.23.1Boot Agent Main Setup Options (Word 30h)

The boot agent software configuration is controlled by the NVM with the main setup options stored in word 30h. These options are those that can be changed by using the Control-S setup menu or by using the IBA Intel Boot Agent utility. Note that these settings only apply to Boot Agent software.

Bit

Name

Description

 

 

 

 

 

PXE Presence.

 

 

Setting this bit to 0b Indicates that the image in the Flash contains a

 

 

PXE image.

15

PPB

Setting this bit to 1b indicates that no PXE image is contained.

The default for this bit is 0b for backwards compatibility with existing

 

 

systems already in the field.

 

 

If this bit is set to 0b, EEPROM word 32h (PXE Version) is valid. When

 

 

EPB is set to 1b and this bit is set to 0b, indicates that both images are

 

 

present in the Flash.

 

 

 

 

 

EFI Presence.

 

 

Setting this bit to 1b Indicates that the image in the Flash contains an

 

 

EFI image.

14

EPB

Setting this bit to 0b indicates that no EFI image is contained.

The default for this bit is 0b for backwards compatibility with existing

 

 

systems already in the field.

 

 

If this bit is set to 1b, EEPROM word 33h (EFI Version) is valid. When

 

 

PPB is set to 0b and this bit is set to 1b, indicates that both images

 

 

(PXE and EFI) are present in the Flash.

 

 

 

13

Reserved

Reserved for future use. This bit must be set to 0b.

 

 

 

 

 

Force Full Duplex.

12

FDP

Set this bit to 0b for half duplex and 1b for full duplex.

 

 

Note that this bit is a don’t care unless bits 10 and 11 are set.

 

 

 

 

 

Force Speed.

 

 

These bits determine speed.

 

 

01b = 10 Mb/s

11:10

FSP

10b = 100 Mb/s

 

 

11b = Not allowed.

 

 

All zeros indicate auto-negotiate (the current bit state).

 

 

Note that bit 12 is a don’t care unless these bits are set.

 

 

 

9
