Well, the ISP 1020 (I need to confirm the part number, as I am still at
work.. ), is on the FWB, JackHammer PCI card. I am using it in SCSI-3
ultrawide mode with wide devices connected. Works fine with MacOS 9.1,
however, that would be expected.

What I should do, is  to get a dmesg output on boot, PCI bus probe
information, etc to give you a more complete picture. I will see if I can
get this over the week end.

Regards,

Andre'
