I was looking in the CyberStorm manual I have for my card. And it does
mention conflicts. However it pertains to the A3000 series. Both the
A3000D and T models conflict as the INT2 line is sent to the CPU slot. And
these machiens required a mod to fix this.
Regarding the A4000T it does not mention any conflict but says to read the
chapter on expansion in the Amiga manual and that jumpers J100 and J104
must be set to internal! Have you done this Merv?
Are you sure your terminators are on correctly? We know what happened with
OS4. And your comment "It doesn't matter" regarding terminators doesn't
give confidence the machine is correctly set up.
I'd simplify the set up, say one HD and a terminator. Looking at my A4000 I
have the A4091 terminator after my HD on my CyberSCSI. And external set to
off. I know Merv loves SCSI but IDE is a lot simpler!
I also slotted in an A4091 into my machine and it still worked fine. It had
no conflict. So rather than be confused Merv check your machine! I know
you can do it.
Also, check Mask and MaxTransfer. Have these been checked. Given how
technical these are I always wondered why they didn't let the driver work
it out. I's tripped me up before.
