I felt like attacking people when I installed my Blizzard SCSI-IV kit too...
:-D
For a start it's a real 'bitch to fit in, particularly with a SIMM and finding the right way around for the SCSI-IV to ribbon connector.
My DCE SCSI-IV has the v8.5 ROM which I was told would be good for CD burning. The trouble I have is there's a large capacitor right where the 2nd SIMM slot is, effectively blocking me from installing another SIMM!
I suppose BlizKick will put a v8.5 SCSI-IV ROM into memory for you, there's got to be a reason for the 8.1 -> 8.5 update.
Where is your SCSI-IV utils? Mine came with SCSIconfig and UnitControl. These not only prep your SCSI hard disk (enabling Synch & Reselect) but also allow you to adjust transfer rates, scan the SCSI bus and stop drive motors.
One other problem I have had with my SCSI-IV is that the I get erroneous data transmissions even in Asynch mode. I think it was Castellan that told me the 'zebra connector' was known to make a bad contact now and then.
Pulling the connectors on and off can sometimes make a better connection (tarnished by heat/oxidising).
Also, remember with SCSI-2 that you must not have a chain longer than 3m and that no two IDC headers must be within 10cm of eachother on a ribbon. The less connectors the better (RF reflection) and active termination (such as a Honda ribbon or external LED block) are essential to absorb reflection.
Termination can be applied with jumpers on most internal drives. Term power also needs to be guaranteed.
