Appendix D: Using the Adaptec Flash Utility 121

Updating the Flash Using the AFU Command Line

1Create the firmware update disks (see page 117).

2Shut down your operating system and reboot to DOS from a bootable DOS floppy disk or from a DOS partition on a bootable drive. (You can use a disk connected to the controller you’re updating.) If your computer isn’t set up to boot from the bootable floppy disk or a bootable device other than a disk drive, enter the system setup utility to change the setting.

3Insert the firmware update disk containing AFU.exe

4At the DOS command, if you have multiple controllers and you don’t know the number of the controller you want to update, type AFU LIST, then press Enter. Otherwise, skip to the next step.

5At the DOS command, type AFU followed by a command (see page 118) and any switches you want.

6Update the flash using the instructions suitable for your requirements:

To update a single RAID controller:

AFU UPDATE /C <cont_number>

Where <cont_number> is the number of the RAID controller whose firmware you are updating. For example, to upgrade Controller 0, type AFU UPDATE /C 0

To update multiple RAID controllers:

AFU UPDATE /C <cont_number_a>,<cont_number_b>

Where <controller_number_a> and <controller_number_b> are the numbers of the Adaptec RAID controllers whose firmware you are updating. For example, to upgrade controllers 0, 2, and 3, type AFU UPDATE /C 0, 2, 3

To update all RAID controllers simultaneously:

AFU UPDATE /C all

Note: The UFI file identifies the RAID controllers, so you don’t have to worry about flashing the wrong controller.

7When prompted, insert the first firmware disk into your floppy disk drive. The AFU reads the first disk.

8When prompted, remove the first firmware disk and insert the second firmware disk into your floppy disk drive.

9Repeat Step 8 as required until the flash update is complete.
