This file provides basic configuration information for the ULTRA 24F family
of SCSI controllers.  For a more detailed instructions, please refer to the
appropriate User Manual.

1. Jumper Settings

   (note : * denotes default settings)

   JP7 : Floppy Control

   JPTP : Terminator Power Control (Applies to ULTRA 24FA and 24FG only)

       * IN : The 24FA/FG supplies terminator power for SCSI pin 26
        OUT : Terminator power supplied from SCSI pin 26

   The following options are independent to ULTRA 24F, ULTRA 24FA,
   and ULTRA 24FG EISA SCSI controllers.

                                ULTRA 24F/24FA                  ULTRA 24FG

       ISA Mode Selection       *Disable /                         N/A
                                 Primary (1F0-1F7, 3F6-3F7) /
                                 Secondary (170-177,376-377)

       SCSI Terminator               N/A                        *Enable /
                                                                 Disable


3. Connectors

   J1  : 50 pin internal SCSI connector
   J2  : 50 pin high density external SCSI connector
   P3  : 34 pin internal floppy connector
   JP1 : 4 pin controller activity LED connector


4. 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 configured to.

   The ULTRA BIOS utility displays SCSI ID, type, manufacturer, model number, 
   and mapping mode for each SCSI device attached to the ULTRA 24F family of
   controllers; 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.
