50 Getting Started with PowerPC Open Firmware
1. Using the keyboard or mouse, select the Save the Existing
ROM option and respond to the prompt by removing all
tapes and disks from the system.
Disks and tapes should be removed from the system since the
ROM image is saved to the first formatted disk or tape found.
2. Insert a DOS formatted disk or tape on which to store the
saved ROM image.
Note No special formatting of the disk is required if a
preformatted (IBM format) high density floppy disk is
used. Otherwise, format the floppy disk using a FAT
(File Allocation Table) format, such as AIXÕs dosformat
command.
3. If the disk needs to be formatted at this time, enter an N to
return to the Update The Firmware menu.
Since PowerPC Open Firmware does not provide formatting
capabilities, an operating system that supports DOS
formatting needs to be booted, or you may format at another
system that provides the DOS format capability. Format the
disk and restart the Save the Existing ROM process.
4. Insert the formatted disk or tape and respond by answering
Y to the prompt.
If the firmware is running on a MVME2600/3600 Series
product, continue with step 5. For all other products skip to
step 6.
5. 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.
