where d is any available drive letter. You now can access the EFI system
partition as you would any other system drive.
4. Create a directory on the EFI-system-partition drive (d:) to store the firmware
update files.
5. Go to the IBM support site at http://www.ibm.com/pc/support/; then, download
the update package for the xSeries 455 server to the directory that you created
in step 4.
6. Extract the xSeries 455 update package into the directory that you created in
step 4.
Notes:
a. When you extract the files, be sure to maintain the folder structure.
b. Detailed instructions for updating the firmware are provided in the readme
file in each code-specific folder.
7. Shut down the operating system; then, restart the server to the EFI shell.
8. Change to the file system (fsx:) that corresponds to the EFI system partition;
then, change directories to the update directory.
9. Follow the instructions provided in the package readme.txt files to install the
firmware updates.
Creating an update CD when using SLES8
If you are using the SLES8 operating system, use the instructions in this section to
create a firmware update CD from the ISO image; then, see the readme.txt file in
the root directory of the firmware update CD, under EFI.
Note: Detailed instructions for using the CD to update the firmware are provided
with the code in each code-specific subdirectory.
The Linux IDE ATAPI CD-ROM device driver uses SCSI emulation for CD read and
write operations. If a boot option to enable IDE-SCSI emulation was not included
during the installation process, you must add the boot option to the elilo.conf file. In
most cases, the IDE DVD/CD-RW drive in the xSeries 455 server is the first IDE
device. To enable the IDE-SCSI emulation, add the following boot option to the
stanza for the kernel you are booting:
append="hda=ide-scsi"
For example, the kernel might have the following stanza:
image=/vmlinuz
label=linux
root=802
initrd=/initrd
append="console=ttyS0,115200n8, console=tty0"
After it is modified, the stanza appears as follows:
image=/vmlinuz
label=linux
root=802
initrd=/initrd
append="console=ttyS0,115200n8, console=tty0 hda=ide-scsi"
Restart the server.
Complete the following steps to create the CD:
