3Copy the file AFU.exe (from the Adaptec Installation DVD) and the firmware image files (typically *.ufi) to a bootable DOS floppy disk, USB flash drive, or writable CD-ROM.

Note: Due to space limitations with floppy disks, you may need to create multiple floppy disks for each firmware image.

4Power off your computer, disconnect the power cord, then open the cabinet following the manufacturer’s instructions.

5Disconnect all cables from the controller, then attach a shorting jumper to the Mode 0 flash connector.

Note: To locate the Mode 0 flash connector on your Adaptec RAID controller, see the figures in About Your RAID Controller on page 17.

6Reconnect the power cord, power on your computer, then boot to the drive containing the AFU.exe file (see Step 3).

7 At the prompt, type <drive-letter>:\afu update /c x

where drive-letteris the drive identifier (a for a floppy drive, for instance) and x is the controller number.

Note: You will be prompted to insert other disks, as needed.

8When the flash is complete, power off your computer, disconnect the power cord, then remove the jumper.

9Close the computer cabinet, reconnect the power cord, then power on your computer. The controller should boot correctly.
