I have an EISA system with the DTC 3292 SCSI-II board. I was wondering
how much of an improvement there would be in performance to write a driver
for the board that uses EISA mode? Would it be possible to incorporate
the FAST transfers also?
Thanks,
Terry
PS: Right now on just the comand "dd if=/dev/sda0 of=/dev/null" command I can
get a 2Megs/sec transfer rate.
