Selects the agent’s boot order setup mode.
This field changes the agent’s default behavior in order to make it compatible with systems that do not
completely support the BBS and PnP Expansion ROM standards. Valid values and their meanings are:
000b
001b
010b
011b
100b
101b
110b
111b
Normal behavior. The agent will attempt to detect BBS and PnP Expansion ROM support as it
normally does.
Force Legacy mode. The agent will not attempt to detect BBS or PnP Expansion ROM supports
in the BIOS and will assume the BIOS is not compliant. The user can change the BIOS boot
order in the Setup Menu.
Force BBS mode. The agent will assume the BIOS is BBS-compliant, even though it may not
be detected as such by the agent’s detection code. The user can NOT change the BIOS boot
order in the Setup Menu.
Force PnP Int18 mode. The agent will assume the BIOS allows boot order setup for PnP
Expansion ROMs and will hook interrupt 18h (to inform the BIOS that the agent is a bootable
device) in addition to registering as a BBS IPL device. The user can NOT change the BIOS
boot order in the Setup Menu.
Force PnP Int19 mode. The agent will assume the BIOS allows boot order setup for PnP
Expansion ROMs and will hook interrupt 19h (to inform the BIOS that the agent is a bootable
device) in addition to registering as a BBS IPL device. The user can NOT change the BIOS
boot order in the Setup Menu.
Reserved for future use. If specified, is treated as a value of 000b.

Reserved. Must be 0.
Disable Flash Update.
If this bit is set to 1, the user is not allowed to update the flash image using PROSet. Default value is 0.
Disable Legacy Wakeup Support.
If this bit is set to 1, the user is not allowed to change the Legacy OS Wakeup Support menu option.
Default value is 0.
Disable Boot Selection.
If this bit is set to 1, the user is not allowed to change the boot order menu option. Default value is 0.
Disable Protocol Select. If set to 1, the user is not allowed to change the boot protocol. Default value is
0.
Disable Title Message.
If this bit is set to 1, the title message displaying the version of the Boot Agent is suppressed; the
Control-S message is also suppressed. This is for OEMs who do not wish the boot agent to display any
messages at system boot. Default value is 0.
Disable Setup Menu.
If this bit is set to 1, the user is not allowed to invoke the setup menu by pressing Control-S. In this
case, the EEPROM may only be changed via an external program. Default value is 0.
3.4.2.4.3 PXE Version – Word 0x32
Word 32h of the EEPROM is used to store the version of the boot agent that is stored in the flash image.
When the Boot Agent loads, it can check this value to determine if any first-time configuration needs to
be performed. The agent then updates this word with its version. Some diagnostic tools to report the
version of the Boot Agent in the flash also read this word. The format of this word is:
Bit(s)
Name
Function
15 - 12
MAJ
PXE Boot Agent Major Version. Default value is 0.
