The level of change to the binary needed to make the ip32PROM=20 I'd not bet my a** on that. Modifying the binary firmware has got a=20 long, but rare, history. I remeber hacked PROM images for VAXen to support larger SCSI disks. As long as you don't require a detailled CPU detection, that should be possible. Hardcoding some values isn't all thaaat hard. Making it correctly (preserving the formerly running detection code for other CPUs) is a bit harder, of course :-) MfG, JBG --=20 Jan-Benedict Glaw jbglaw@lug-owl.de . +49-172-7608481 = _ O _ "Eine Freie Meinung in einem Freien Kopf | Gegen Zensur | Gegen Krieg = _ _ O fuer einen Freien Staat voll Freier B=FCrger" | im Internet! | im Irak! = O O O ret =3D do_actions((curr | FREE_SPEECH) & ~(NEW_COPYRIGHT_LAW | DRM | TCPA)= ); --hVUY+LYn0LT07sdA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) iD8DBQFBPvdsHb1edYOZ4bsRAiNFAJ0c0gaaXpLQNRDexg96xJGfCHzxLACbByRK jaLTn+870/irCBtBg2c2aaU= =lDqL -----END PGP SIGNATURE----- --hVUY+LYn0LT07sdA--
