YEEESSSSSSS!!!!!!!
.... sorry I didn't mean that in a bad way but it is just more
evidence that there is something wrong/screwy about the
CyberstormPPC/MkIII UltraWide SCSI interface.
Luckily for you I can tell you how to fix it (or rather cludge it) :
In the boot menu of the Cyberstorm force the drive into synchronous
mode of 10Mhz or less ... I know what you are thinking "But it'll run
horrible slow!" ... don't worry.
Boot the machine and add the following line to the startup-sequence
or user-startup :
unitcontrol Unit 1 Wide Period 40 Offset 15
Now things should be MUCH faster on your SCSI disk.
unitcontrol is in one of the archives for the cyberstorm .. you
should have it, if not e-mail me and I will send the archive to you.
Why do you need to do this ... not 100% sure but there seems to be an
incompatibility with the new Ultra2/Ultra160/320 drives and the
Cyberstorm, luckily this should be fixable with a new firmware ...
unluckily Ralph Schmidt isn't really interested in doing it or
letting anyone know how to do it, he has however offered to look into
it but I need to get MorphOS installed first as he wants to make a
debug version of cybppc.device for MorphOS to do it ... send him an e-
mail and see what he says.
Regards
Mark
