Maybe I'm naive, but why then your disk drive and CD would spin? Aren't they spinned by OpenFirware, or just by having power applied to them? I wouldn't think you could alter the entry point for Open Firmware, but that you could alter the initialization process after Open Firmware has started. Booting from CD, or simply don't booting maybe will do the trick. AFAIK, the trick is getting to boot without the hard disk attached so that OF will try the default initialization methods, namely the CD or floppy. But maybe I've just misunderstood the method. Anyway no hurt in trying. --_ / \ Leandro Guimarães Faria Corsetti Dutra +55 (11) 246 96 07 resl \ / Amdocs Brasil Ltda, Sao Paulo +55 (11) 3040 8913 coml X http://terravista.pt./Enseada/1989/ ; mailto:leandrod@amdocs.com / \ Campanha fita ASCII, contra correio HTML BRASIL > > -- > rob off list/ng replies: > rob@impure.org.uk > > > -- > To UNSUBSCRIBE, email to debian-powerpc-request@lists.debian.org > with a subject of "unsubscribe".
