Ah, yes, i enabled it on Jeff's suggestion.

Well, it is a blank disk indeed, so this is no suprise.

Trying to partition the disk with parted yielded the last set of debug
messages, and a : 

Error: Unable to open /dev/sda - unrecognized disk label.

The same when trying to write a partition table to it, and naturally, there is
no partition afterward.

hexdump yielded only the debugmessages and nothing else.

Mmm, this is a G3, while i have a G4. The G4 does some I/O reordering, which
we don't have with a G3, so this may be the cause. 

Do you have a mac version of the board, with a forth/OF bios in it ? Or a
normal PC card, which is thus uninitialized ?
