Hi Managers,

we are using some KZPCA-AA (=KZPCA-AX) SCSI-Controllers.

I opened the bus to insert 73 GByte disks which are not jumpered to force
single ended, and i got some BUS-Reset Messages.

Okay - i opened the bus.

But:

What does it mean HVD mode - Compaq/HP techniker doesn't know about it.

Thanks, Harald
