How to recognize update files used with Flash Update: Diagnostics update file are named MZYT*.US1, where * will be a two-digit number indicating the level of the ROM Diagnostics code followed by optional additional characters. For example, MZYT05A.US1. Firmware POST/BIOS update file are named MZKT*.FLS. For example, MZKT19AUS.FLS. To see the current version of system components, run ver in the EFI shell. To update the system firmware and the diagnostics (we always recommend you do both at once), follow these steps: Tip: A full backup should be completed and verified prior to running this, or any other system upgrade. 1. Select Flash Update from the Boot Manager menu. The Flash Update utility will display. 2. Press 1 to update the POST/BIOS from the menu. 3. You will be asked if you wish to change the serial number, the machine type and the asset tag. Typically, you would answer no. 4. You will then be asked if you would like to save the current code to a disk. If you select Y, you need to specify a file name for the backup. The Flash Update utility saves the backup file to the writable file system with lowest file system identifier number (FSx). In most cases this is EFI System Partition, if it exists. If the operation fails, make sure some sort of writable media is attached to the system. CD-R/W and MemMap mappings are not considered writable devices in EFI. In our system, as shown in Figure 4-2 on page 70, the backup file would be saved on fs3. Do not try to specify full path to the file name, because the utility does not accept full path syntax. 5. At this point, the Flash Update utility should detect the presence of the update files on the disk, and you will be asked to choose which language you wish to use during POST and in Setup. 6. Once the flash update completes, you will be prompted to press Enter to restart your system. 7. After rebooting, return to the Flash Update utility. 8. Enter 2 to select Update Diagnostics from the menu. Chapter 4. Installation 81

Chapter 4. Installation
81
To see the current version of system components, run
ver
in the EFI shell.
To update the system firmware and the diagnostics (we always recommend you
do both at once), follow these steps:
1. Select
Flash Update
from the Boot Manager menu. The Flash Update utility
will display.
2.
Press 1 to update the POST/BIOS from the menu.
3.
You will be asked if you wish to change the serial number, the machine type
and the asset tag. Typically, you would answer no.
4.
You will then be asked if you would like to save the current code to a disk.
If you select
Y,
you need to specify a file name for the backup. The Flash
Update utility saves the backup file to the writable file system with lowest file
system identifier number (FSx). In most cases this is EFI System Partition, if it
exists. If the operation fails, make sure some sort of writable media is
attached to the system.
CD-R/W and MemMap mappings are not considered writable devices in EFI.
In our system, as shown in Figure 4-2 on page 70, the backup file would be
saved on fs3. Do not try to specify full path to the file name, because the utility
does not accept full path syntax.
5.
At this point, the Flash Update utility should detect the presence of the update
files on the disk, and you will be asked to choose which language you wish to
use during POST and in Setup.
6.
Once the flash update completes, you will be prompted to press Enter to
restart your system.
7.
After rebooting, return to the Flash Update utility.
8. Enter
2
to select
Update Diagnostics
from the menu.
How to recognize update files used with Flash Update:
Diagnostics
update file are named MZYT*.US1, where * will be a two-digit number
indicating the level of the ROM Diagnostics code followed by optional
additional characters. For example, MZYT05A.US1.
Firmware POST/BIOS update file are named MZKT*.FLS. For example,
MZKT19AUS.FLS.
Tip:
A full backup should be completed and verified prior to running this, or
any other system upgrade.
