Compression used for IBM BIOS images?

inconel · Sun Sep 19, 2004 9:45 am

Does anyone know what type of compression IBM uses for their distributed BIOS images? I'd like to separate all the chunks with Phoenix BIOS Editor, but I need to decompress the file first. This is the BIOS I'm interested in http://www-1.ibm.com/support/docview.ws ... us&lang=en
Thanks for any help you can give.

I have the same problem too, but in future there will be an uncompressor.....

You can try to dump / create an uncompressed backup of your BIOS:

Then try to modify the backup with PhoenixBIOS-Editor....
You can send me the back up BIOS file too.

Hi.
To uncompress IBM/Phoenix compressed BIOS files you can take:

"PHCOMP"

I did not know that it is part of the BNOBTC all the time.

It is also available from here:
http://bnobtc.pix-art.com/bnobtc-files/phoenix/

Just run:
phcomp /d <Phoenix BIOS file>

Borg Number One,

Thank you! That seems to work nicely.
