Right! Bad, but it is so!

We should test if the generic kernel works for all subarchs.
What is Majos meaning, will he upload a newer kernel-package in the next days?

Good! With our patches, the make-kernel package can handle this.

:-) Yeah, as the sparc people! WIth ext2, we can remove minix support.

hmmmm PowerMac use hfs, PReP and MBX msdos and i think CHRP can do both.
All CHRP boxes i know uses msdos partition table format.

Right. Q: can PowerMac read normal iso9660 cds?

No, not yet, but i hope we have one or more Apus systems in Oldenburg. Sven???
