BIOS Upgrade
The following instructions detail the steps that need to be taken in order to upgrade
the BIOS of your Ultra100 TX2 controller card. BIOS (Basic Input/Output System)
controls the booting operation of the Ultra100 TX2. If you receive information
regarding an update for the Ultra100 TX2 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 Ultra100 TX2 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 Ultra100 TX2 BIOS, and an “Update Success”
message will appear.
2. Restart the system.
NOTE: When the Ultra100 TX2 BIOS appears, make sure that the BIOS version is
the new version.
