Boot Agent Configuration Customization Options (Word 0x31)
Word 0x31 contains settings that can be programmed by an OEM or network
administrator to customize the operation of the software. These settings cannot be
changed from within the Control-S setup menu or the IBA Intel Boot Agent utility. The
lower byte contains settings that would typically be configured by a network
administrator using the Intel Boot Agent utility; these settings generally control which
setup menu options are changeable. The upper byte are generally settings that would
be used by an OEM to control the operation of the agent in a LOM environment,
although there is nothing in the agent to prevent their use on a NIC implementation.

Set these bits to 11b to indicate valid data.

Continuous Retry Disabled (0b default).
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 = Normal behavior. The agent attempts to detect BBS and PnP
Expansion ROM support as it normally does.
001b = Force Legacy mode. The agent does not attempt to detect BBS
or PnP Expansion ROM supports in the BIOS and assumes the BIOS is
not compliant. The BIOS boot order can be changed in the Setup Menu.
010b = Force BBS mode. The agent assumes the BIOS is BBS-
compliant, even though it might not be detected as such by the agent's
detection code. The BIOS boot order CANNOT be changed in the Setup
Menu.
011b = Force PnP Int18 mode. The agent assumes the BIOS allows
boot order setup for PnP Expansion ROMs and hooks interrupt 18h (to
inform the BIOS that the agent is a bootable device) in addition to
registering as a BBS IPL device. The BIOS boot order CANNOT be
changed in the Setup Menu.
100b = Force PnP Int19 mode. The agent assumes the BIOS allows
boot order setup for PnP Expansion ROMs and hooks interrupt 0x19 (to
inform the BIOS that the agent is a bootable device) in addition to
registering as a BBS IPL device. The BIOS boot order CANNOT be
changed in the Setup Menu.
101b = Reserved for future use. If specified, treated as value 000b.
110b = Reserved for future use. If specified, treated as value 000b.
111b = Reserved for future use. If specified, treated as value 000b.
Reserved, must be set to 00b.
Disable Flash Update
If set to 1b, no updates to the Flash image using PROSet is allowed.
The default for this bit is 0b; allow Flash image updates using PROSet.
Disable Legacy Wakeup Support
If set to 1b, no changes to the Legacy OS Wakeup Support menu
option is allowed.
The default for this bit is 0b; allow Legacy OS Wakeup Support menu
option changes.
Disable Boot Selection
If set to 1b, no changes to the boot order menu option is allowed.
The default for this bit is 0b; allow boot order menu option changes.
