A Mode 0 flash should be performed if it appears that the firmware/BIOS of the RAID controller has become corrupt or if a previous flash update failed. Behavior may include:
- The inability to update the firmware/BIOS via the flash utility or Adaptec/ICP Storage Manager.
- The absence of the BIOS message from the controller during boot up.
- The inability to have the system boot even if the BIOS message is displayed (system hang conditions).
- BIOS messages like "Unknown firmware error" or "Controller Kernel Panic".

Note: If the controller is not responding, then it should be MODE 0 flashed to the current installed firmware version. If there is a newer firmware update available for the controller, it is recommended not to update to the newer image until the controller is responding properly.

This method requires a bootable DOS diskette and two or more blank formatted floppy disks.

Floppy Disk Creation
1. Download the firmware file for the controller from our Support site.
2. Unzip the self extracting file.
3. Copy the ***01.ufi file and afu.exe (for Adaptec) or ifu.exe (for ICP) files to floppy disk no. 1.
4. Copy the remaining ***.ufi files to individual floppy disks (one ***.ufi file per floppy disk).

The expanded files can also be copied to a USB device or CD-R.

Procedure for MODE 0 flash:
1. Power off the system and disconnect all cables from the controller.
2. Attach a shorting jumper to the Mode 0 flash connector marked " FLASH ":
On 2130SLP, 2230SLP, ICP9014RO, ICP9024RO: J2
On 2810SA, 21610SA: J12
On 2420SA, 2820SA, ICP9047MA, ICP9087MA: J10
On Series 5 (5405, 5405Z, 5445, 5445Z, 5085, 5805, 5805Z, 51245, 51645, 52445), Q Series (2405Q, 5805Q, 5805ZQ), and Series 2 (2405, 2045, 2805): J8
Series 6 / 7 / 8 RAID controllers support a reset protocol called HDA mode flash. For information about HDA mode, contact Adaptec by PMC Technical Support for further assistance.
On all other Controllers: J6

Note: The following controllers are not capable of a Mode 0 flash:
Series 1 (1045 and 1405) HBAs
Series 6H and 7H HBAs
HostRAID and SCSI cards

3. Power on the system and boot to DOS from a bootable floppy disk, USB device or CD-ROM.
4. Using the floppy disk no. 1 (or the USB device or CD-R) you created type 'afu' using Adaptec Controllers or 'ifu' using ICP controllers at the DOS prompt.
5. Select 'Update flash image' from the menu and follow the prompts.
6. When the flash is complete, power off the system and remove the Mode 0 jumper from the controller.
7. Power on the system and verify the RAID controller completes the boot process correctly.

If the controller still fails to respond, please contact Adaptec by PMC Technical Support for further assistance.
