Compression used for IBM BIOS images?

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

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.
