F80安裝AIX5版本的操作系統，之前也不確認是否能安裝，直接用光盤引導，液晶屏停在E443，以前也碰到過，還是按以前的做法，讓NVRAM放電，再從硬盤引導，lsdev -vp |grep alterable或lscfg -vp|grep -F .CL查看當前微碼級別，然後確定當前微碼不能安裝AIX5版本的操作系統，確定原因之後，到IBM下載微碼，filename :7025F80F.BIN ，ftp到服務器

Updating the Firmware
***
WARNING:
Do not power off the target server at any time before the update process completes. Be sure the system is NOT running any user applications.
***
Note: Checksums can be used to verify files have not been corrupted or altered during transmission.
－－－－－－－－－－－－－－－－－－－－－－－－－－－－
At the AIX command line, enter:
sum CL060505.img
This command will produce the following output:
52328 3217 CL060505.img
The checksum is ----> 52328

cd /usr/lpp/diagnostics/bin
./update_flash -f /tmp/fwupdate/CL060505.img
You must have root authority on the target server to update its firmware.
-----------------------------------------------------------
As the firmware update takes place (during the automatic shutdown sequence), progress can be monitored from the operator panel. The checkpoints 99FF and 99FD alternately appear while the update is in progress.
At some points in the update process, these checkpoints may not change for ten to thirty minutes. If this occurs, be patient and allow time for the update process to complete.
Updating firmware must be initiated either directly from the AIX command line, from the Update Flash Diagnostic Service Aid, or from the Service Processor Menu.
