Updating the system firmware images

Once the system firmware is updated, the QS22 blade server boots from the new

TEMP This is the firmware image normally used in the boot process. When the
PERM This is a backup copy of the system firmware boot image. The blade server
Once you have updated the system firmware and booted the blade server, you

For example, to extract the image package ibm_fw_bios_qb-1.9.1-2.sh from
ibm_fw_bios_qb-1.9.1-2_linux-pq_cell.sh in the directory /temp/fwimage
enter:

If the directory does not exist the firmware package creates it.
