The firmware and the DPT I2O BIOS for SmartRAID V controllers are contained in flash ROM and may be upgraded by using SMOR. SMOR itself is also part of the ROM and can be upgraded.

Each firmware image is contained in a .FWI file. Each DPT I2O BIOS image is contained in a file named I2OBIOS.xxx (where xxx is the BIOS version number).

** It is much easier to perform the following procedure if the **
** image files are placed in the root directory of a diskette. **

BOOT YOUR SYSTEM AND ENTER THE SMOR UTILITY ( Control-D )

1. In the left pane, select the controller that you wish to update.
2. Select "Flash HBA" on the "Action" menu. The source file browser will appear.
3. Place the diskette containing the image files in the diskette drive. Select the drive on which you placed these files in the source file browser window and press Enter to expand the drive listing.
4. Highlight the desired image file and select "Ok" to upgrade the controller. After the controller reads the image, it will display the version number of the firmware or BIOS. Select "YES" to confirm.
5. After about 10 seconds, the controller firmware or I2O BIOS will be upgraded.

If a firmware upgrade is unsuccessful, causing the controller to hang, the new firmware can be temporarily disabled and the upgrade attempted again by following the steps below:

1. Power-off the system.
2. PM1554, PM2554 and PM2654 controllers - remove any RA4050 or SX405x expansion modules from the controller.
3. PM1554, PM2554 and PM2654 controllers - place shorting jumpers across pins 1 and 2 and pins 3 and 4 of P9 on the controller.

   PM375x controllers - move the shorting jumper from pins 3 and 4 of P9 to pins 1 and 2.(from RUN to LOAD)

4. Power-up the system. Start SMOR and attempt the update again.
5. Power-off the system and return the jumpers to their original positions.
6. Reattach the expansion module to the controller card and insert the card in a host system PCI slot.
