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.

Description
Signature
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.
