If it is a Blizzard 1230IV it works FINE. I had one among with Squirrel SCSI attached to the PCMCIA port and it worked just fine :) (with 3.0 roms)
Something else is wrong...


Ah, the Squirrel... A guy I used to know (alas I haven't seen him in ages - maybe he's a member here, hi Mike) had one of those and found it seriously slow on his 68060 card. It turns out the driver was using the MOVEP instruction, which was being emulated on 060, which being from   the Apollo stable didn't have the best handling code.
He actually patched the offending code with a reassembler, getting a serious performance kick :-)
