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.
Reserved, must be set to 00b.
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 may 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.
