To PowerPC Open Firmware From Open Firmware
Follow these steps to update to PowerPC Open Firmware from an
earlier version of Open Firmware.
1. Using the keyboard or mouse, enter the Administrative
Options menu.

3. Select Update The Firmware ROM option.
The following prompt appears:
Insert Bootable Disk or Tape with Firmware Upgrade
Proceed? (Y/N)
4. Insert the bootable floppy disk or tape into the appropriate
drive and enter a Y to continue the update process. Enter an
N to return to the Update the Firmware menu.
5. If you enter a Y and the firmware is running on a
MVME2600/3600 Series product, continue with step 6. For all
other products skip to step 7.
6. Firmware running on a MVME2600/3600 Series product
displays the following prompt:
Select Flash Bank:
(A) Bank A
(B) Bank B
Bank? (A/B)
Make your selection by entering either A or B.
Note Because MVME2600/3600 Series products provide two
distinct flash memory banks, selection of a bank is
required. Only the first megabyte is updated to flash
memory due to the limitations of the floppy disk
medium.
