3. ULTRA BIOS Utility
To invoke the on-board BIOS utility, after a full system bootup to DOS
operating system, use the DOS "DEBUG" program to access the BIOS utility:
a. Load the DEBUG program by typing
DEBUG after the DOS prompt ( ">" sign )
b. Once in the DEBUG program, following the prompt ( "-" sign ), type
g=c800:5 or
whatever BIOS address the board is jumpered to.
The ULTRA BIOS utility displays SCSI ID, type, manufacturer, model number,
and mapping mode for each SCSI device attached to the ULTRA 14F; it also
provides functions for exercising SCSI devices.
Verify : Non-destructive media verfication for hard disks, removable hard
disks and magneto optical devices.
Scan : Same function as verify except it will issue "reassign bad
block" to the drive when defective sectors are found.
Format : Low level format of the SCSI device.
CFormat: Low level format of the SCSI device with the certification
option (CLIST) which re-sequences the good blocks.
