Plug & Play OS
If enabled, this option informs the System BIOS that the operating system that is
booted supports Plug and Play. This has the effect of forcing the Plug and Play
portion of the System BIOS to only configure motherboard devices and those
peripherals that are necessary for booting (display, hard disk, etc.), the rest being left
to the operating system to configure. The default is “No ”.
Reset Configuration Data
If enabled, this option clears the Extended System Configuration Data (ESCD) block
residing in Flash Boot Device (FBD) main block #2. This is necessary the first time a
system is turned on or if the ESCD becomes corrupted. The default is “ No” . This
option is automatically reset to “No ” after the ESCD is cleared.
Halt on watchdog reset
If enabled, this option causes the System BIOS to halt the boot process if it detects
that a watchdog timer reset occurred. The default is “Disabled ”.
Large Disk Access Mode:
If a hard disk larger than 528MB is being used, this selection should be set to “ DOS”
if running MS-DOS, or set to “ Other” if using a different operating system. When set
to “ DOS” , this selection causes the System BIOS to perform cylinder/head translation
if the drive is configured in Setup to have more than 1024 cylinders. This allows MS-
DOS systems to use hard disks up to 8GB (1024C x 255H x 63S) in size without
special drivers or LBA. The default is “DOS ”.
User BIOS Extensions
These items control the loading (shadowing) of BIOS extensions contained in the FBD
main block #3. Note that there are actually three groups of Setup items to control the
shadowing of up to three BIOS extensions. The screen graphic only shows the first
group.
BIOS Extension Offset in FBD:
This option selects the source address of the BIOS extension located in the FBD. The
address is an offset from the base of the FBD. The offset range is between 46000h
through 5FFFFh in 8KB increments. The default is “Disabled ”.
