 Hi Barry,

 What sort of problems have you been having? Practically all of my G4s are
SCSI only (including my home machine) and I haven't had any problems
whatsoever with the installer. I suspect the problem might be with your
SCSI card. Which one do you have? All of mine are the ExpressPCIUL2Ds

 Yeah, it is a bit of a pain that the default kernel doesn't have himem
support. If you want, I could send you my kernel config (I simply turned
on HIMEM, removed AppleTalk and other such non-sense and added USB Mass
Storage support for my camera.). Lemme know if you want me to email it to
you.

 No.

 I don't think it should be, but I don't use MacOS any more on my home
machine or my work machines. I just upgraded the HD on my iBook (talk
about PITA!! - http://open.mcgill.ca/ibook_hd_change.jpg), and I installed
MacOS, OS X and YDL on it for fun. I've only booted into MacOS for a few
moments, but I didn't see any Linux partitions.

Cheers,

Chris
