This must be a problem with the disk. I use 2 540 MB IBMs in one box and 1
1 GB DEC in the other box, works fine. RZ23 also works fine, but 100 MB is
a bit small to do useful things :-)

Hey, this is really FAST !!! Without this disconnect hack i tested with
"dd" and got about 35 KB/s. This is due to missing DMA support yet.
Network is definitely faster at the moment (about 360 KB/s), but we should
reach this with SCSI DMA also.

so long.. Michael
