This utility allows you to update the LSI Logic PCI SCSI BIOS on a host 
adapter based on a SYM53C815, SYM53C825, SYM53C825A, SYM53C875, SYM53C876, 
SYM53C885, SYM53C895, SYM53C895A, SYMC53C896, SYM53C1010-33 and SYM53C1010-66
SCSI chip. New versions of the PCI SCSI BIOS are released periodically. Your 
host adapter must have a flash on board to use this utility.

The utility is labeled FLASH8X5.EXE and is located on your LSI Logic SDMS drivers
diskette. It is required that you place this utility on a DOS bootable diskette
and execute it from this diskette. Power down any hard disk drives attached to
the host adapter you are updating.

Using DOS 5.0 or higher, create a bootable diskette by formatting it with the 
/s option (for example, 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 utility, if desired.

Insert the diskette into drive "a:". Boot the system to the DOS prompt a:\>. 
Type FLASH8X5 and press Enter.

Note: Some systems are designed around a PCI bus implementation, which is
      referred to as a Peer Bus design. This design provides an expanded PCI
      bus capacity by means of a secondary PCI bus. This implementation may
      cause issues with this Flash utility's ability to correctly identify 8XX
      boards installed on this secondary PCI bus. 

      For example, an error could occur or the system could become hung up
      after executing this Flash utility. Two alternatives are provided to
      correct these issues if your system contains a Peer Bus implementation:

      1.  Reboot the computer, and try typing FLASH8X5 /q at the prompt to 
          invoke an optional mode of identifying 8XX boards in a secondary PCI
          bus environment.

      2.  If Step 1 fails, move the 8XX boards to be flashed over to the 
          primary PCI bus.

      Note: These two alternatives are the only ones available at this time.

The first screen displayed indicates what files are necessary to upgrade and 
general instructions to upgrade. Press Enter to continue to the next window.

This window is the Main Menu for the Flash Utility and contains these six
choices:

     1. Update the EEPROM.   
     2. Backup the current BIOS image.   
     3. View board summary.   
     4. Exit to DOS.   
     5. Reboot.   
     6. About Flash8x5.   

LSI Logic recommends that you do a view the board summary (option 3) and perform
a backup (option 2) prior to updating the flash. The view identifies the SCSI 
controller, its Device ID, the Flash Chip, and the current BIOS version. The
backup will store the BIOS image currently residing in the flash ROM of the first
board only to the diskette. In the event that there are problems with the new
image, you can get back to the original one.

Now you are ready to update the current SCSI BIOS (option 1). Choosing option 
1 gives you a summary of boards installed to choose from. You must mark at 
least one by pressing the spacebar, even if there is only one to choose from. 
This takes you to a new window where the BIOS file name is provided. After 
marking the board and pressing Enter, a new window appears asking for the 
file name of the BIOS to upgrade. Type the filename in manually at the A:\
prompt and press Enter or press F2 to view the available files on the diskette.
If you press F2, the available files should be: the BIOS file just backed up 
and 8XX BIOS image files. Highlight the 8XX BIOS image file (*.ROM) and press
Enter. 

Next, the utility displays the file name and notifies you when the file is 
successfully read. Press Enter to continue, and the system prompts you whether 
or not to overwrite the BIOS that is currently flashed in. Select "Y" to 
upgrade. This causes the flash to get erased and updated.

The system then displays the card information and verifies that the new BIOS
is flashed. Press any key to get back to the main menu. Choose option 5 to
Reboot. Remove the floppy if you want to boot off your hard drive.

To verify the new BIOS installation, watch carefully during boot and look at 
the 3rd line of the SDMS banner when displayed. Or rerun the Flash utility from
the floppy and choose the view option to see the current BIOS version.

Note: Due to smaller flash ROMs on these host adapters, it may not be possible
      to upgrade earlier host adapters with newer versions of the BIOS. The
      flash ROM size can be determined by the part's description displayed
      on the "Summary of boards installed" screen in the flash chip column.
      Flash ROM part numbers and corresponding sizes are shown below.

      Flash ROM part numbers and corresponding sizes are:

            256/256A  -  32K byte capacity
                 512  -  64K byte capacity
            101/010  -  128K byte capacity
            201/020  -  256K byte capacity
