I have an 8500 with both mesh and a adaptec 2930 card.
I have a yahmaha cd writer on the mesh interface and a 30gig ultra scsi
2 drive on the adaptec 2930.
I rebuilt 2.4.18 several times with the adaptec card as part of the
kernel as well as the mesh drive.
I have no problems.
I have never used dd for reading files but I have loaded addition rpms
from the stock 7.3 cd disks recently.
I know this does not immediately help but if you want me to try out one
of your scripts with an unmounted cd I will be more than glad to!
