Symbios Logic

Instructions for using FLASH8X5.EXE ver 1.05.00
To upgrade the Symbios Logic PCI-SCSI and NCR PCI-SCSI 
Host Bus Adapter Cards.* 

*********************  IMPORTANT   **********************
This Flash utility is not meant to be used with any controller
that uses the 53C810 chipset.  The Mother Board manufacturer
is responsible for any upgrades to the SCSI BIOS.  You need to 
contact them for any type of System/SCSI BIOS upgrade to your
system.  Only the controllers listed below are supported with
this version of the Flash utility. 53C810 controllers DO NOT 
have a Flash ROM on the card, there rely on the System BIOS to 
boot up.
If you are currently using Netware 3.12 or Netware 4.1 or 
OS/2 Warp using the current 3.x BIOS.  DO NOT UPGRADE your
SCSI controller with this BIOS. The programs will not work
with this version of the BIOS. Also the SCSI format program
will not work with this version of the BIOS, because it requires
that DOSCAM.SYS be loaded, which will not work with the 4.0 BIOS.
*********************************************************

If you are not using the operating systems listed above then you
can proceed with these steps to upgrade you Symbios/NCR SCSI 
controller.

1. After you have downloaded the file FLASH4X.ZIP from 
   the BBS (719) 573-3562 or WEB site (www.symbios.com).  Using 
   DOS 5.0 or higher, create a bootable diskette.**
   
   Unzip FLASH4X.ZIP to the root directory of the diskette
   (using PKUNZIP 2.04G) or extract the contents using WinZip.

2. Insert the diskette into drive A:.  Boot the system to the 
   DOS prompt A:\>. 

3. Type FLASH8X5 and press enter.

4. The first screen displayed indicates what files are necessary
   to upgrade and general instructions to upgrade. Press enter
   to continue.

5. The Main window has 7 command lines. First View Board Summary(3).
   Make certain that the utility identifies the SCSI controller, 
   its Device ID, the Flash Chip and current BIOS version.

6. Backup the old version of the BIOS (2) to the diskette.
   Give the file a unique name with a .CSB, .ROM, or .BIN extension.

7. Update current SCSI BIOS (1). Enter the file name of the BIOS to
   upgrade or press F2 to view the available files. There should be
   2 files available: the BIOS file that was just backed up, and 
   8XX_32.ROM.

8. Highlight the file 8XX_32.ROM for the Symbios Logic and NCR Host
   Adapter controllers and press Enter. It will then display the file 
   name and notify you that the file has been successfully read. Press 
   Enter again. The system will prompt you whether or not to overwrite 
   the BIOS that is currently flashed in. Select "Y" to upgrade. The 
   system will then display the card information and verify that the 
   new BIOS is installed. Press any key.  Reboot(6).

9. Verify the new BIOS has been installed by viewing the 3rd line
   of the SDMS banner (which should read PCI-4.03.00) when 
   displayed.

*  Host bus adapter cards supported

   SYM8150SP    		NCR8150S
   SYM8250ASP           NCR8250S
   SYM8251ASP           NCR8251S
   SYM8251AD            NCR8251D
   SYM8751SP
   SYM8751D 
   
  (Previous versions of the host bus adapters use the format NCR8150S, 
   NCR8250S, ...)

** A bootable DOS diskette can be created by formatting it with the /s 
   option (e.g., format a: /s).  Do not install any memory managers or 
   SCSI drivers on the diskette. A minimum of 200K of conventional 
   memory is needed to execute the flash utility. Add the DOS mouse 
   driver to AUTOEXEC.BAT for mouse control of the flash utility.
