BIOS Upgrade

The following instructions detail the steps that
need to be taken in order to upgrade the BIOS of
your Ultra TX controller card. BIOS 
(Basic Input/Output System) controls the booting
operation of the Ultra TX. If you receive 
information regarding an update for the Ultra TX
BIOS (from the Promise Technology website or 
technical support), download the update and then
follow these instructions to install the update.

NOTE: Before updating the Ultra TX BIOS, you can
save the old BIOS by choosing option 1 in the main menu
("Backup Current ROM BIOS to File"). Type the path and
file name where you wish to save the old BIOS 
(i.e., "A:\OLDBIOS.BIN").

1. Create a bootable DOS floppy, and copy the file
"PTIFLASH.EXE" and the file containing the updated 
BIOS to the floppy diskette.

2. The file "PTIFLASH.EXE" is a DOS program; a DOS
boot floppy diskette must be used to run the program.

3. At the "A:\>" prompt, type "PTIFLASH." The main menu
should be generated.

4. In the main menu, choose option 2 - "Update BIOS From
File." In the pop-up dialog box that appears, enter the
path and name of the BIOS file you wish to update to 
(i.e., "A:\ULBIOS.BIN").

NOTE: If, after typing in the path and file name while 
trying to update the BIOS, you receive the message "This
file is not found," make sure you’ve entered the correct
path and file name.

1. The utility will then update the Ultra TX BIOS, and
an "Update Success" message will appear.
2. Restart the system.

NOTE: When the Ultra TX BIOS appears, make sure that the
BIOS version is the new version.
