Firmware on blade

Hi.

I need to update firmware on a Js20 blade server I have and need to do it via Diagnostics CD, rather than using diag in AIX. So a little refresh on how to. Boot of the Diag CD, burn the firmware image to another CD-ROM and all set. Will I need to burn any additional files to the CD containing the .img file? Anything other to watch out for?

yes (i saw the date of the posting, but that was my own actual problem), that's nearly all, first should the service-Processor of the blade been updated (web-based), then the image-File is not an ISO-Image but have to be burned with a file-system as single file on a second cd, vt320-Emulation works fine and F7 should start in the submenu the procedure, after that the blade should be configured/reseted webbased.
