A4091 SCSI Adapter

[Klaus Heinz <klaus.heinz%onlinehome.de@localhost>]

Hi,

has anyone used a A4091 SCSI-Adapter with NetBSD, preferably in an A3000 ?
Any experiences to share or, even better, test results with the bonnie
benchmark (pkgsrc/benchmarks/bonnie) ?

As far as I know this device is a DMA-capable adapter and I would be
interested in transfer rates and CPU usage.

The internal wd33c93 chip in the A3000 gives me these results (68060/50,
IBM-DORS 2GB):

  $ bonnie -d . -s 100
