#Adaptec and Imagine
10 messages in this thread
Hi Imagine users,
Has anyone here an Adaptec VLB SCSI Controller? I just bought one with a 1 gb
IBM HD. Since I have build it in Imagine crashes fequently. When I put it out
everything works fine.
Any ideas that might help are appreciated. -David
David,
Some questions:
1. Did you have a CD driver loaded before on another controller, or have
you just loaded it with this one?
2. Does it work with other programs and just not with Imagine?
3. Did you just add EMM386 or another memory manager to be able to
LOADHIGH the drivers?
4. What version of DOS are you using?
5. What are the settings on your EMM386 or other memory manager?

Hi Marc,
thanks for your reply
>> 1. Did you have a CD driver loaded before on another controller, or

Yes I have a CD-ROM driver and also a second one so that the disk cache
software can cache the CD-ROM, too. But when I "clean-boot" there is no driver
except the mouse driver.
>> 2. Does it work with other programs and just not with Imagine?
It also causes trouble with OzCIS when the controller is in, it's not only
Imagine. Unfortunately OzCIS and Imagine are the two most important programs I
have.

I have DOS 6 and use 386Max 7. But I also tried to boot without anything
(except a mouse driver) and the problems were the same.
>> 5. What are the settings on your EMM386 or other memory manager?
I don't think that the mem manager is the problem. Even when I boot without it
it still crashes.
With some switches I can set different I/O ports for the controller. I
will have to try all of them and see if it helps. Maybe that's the problem. I
don't know much about all these IRQs, I/O ports, memory stuff 🙁 but then I'm
not a developer.

I just started to change the I/O port addresses one by one. I tried the next
address, booted and started Imagine. So far no crash! Maybe I found the right
address right away.
David,
The fact that your adapter causes problems with OZCIS is a strong indication
that you have either address or interrupt problems or both.
I think you are on the track of the solution.

David,
You may also want to make sure there are no BIOS conflicts with the
Adaptec card. Check your CMOS settings and make sure you are not stepping
on memory with shadow ram (that may be used by a ROM on the Adaptec) or
other CMOS settings (i.e. if you have AMI BIOS, there are a lot of
settings in CMOS that can cause problems).

Troy,
thanks for your help. After changing the I/O port address of the adapter I
haven't had any chrashes any more. Looks like it works now.

Glad you got yer machine working again David…..

Yes, I felt really stupid having bought hardware for $1100 only to find out
that it won't work with my favorite software. But now everything works fine
again and it like christmas and birthday at the same time 🙂

To get my Ultrastor 34F to work properly with QEMM, I needed to add a special
patch in CONFIG.SYS before QEMM. In other words, I think there are known
conflicts between some high-speed VLB SCSI adapters and other memory
managers… given that Impulse wrote their own memory manager, it's going to
be tough to find the problem, I'd guess.
Hi, thanks for your reply.
I know of the problem that 386Max has with the Adaptec controller. I had to
add NOIOWRAP in the profile file in order to get the new HD (and the
controller) to run at all. Fortunately I found the problem. I had to change
the I/O port address of the adapter to get rid of the problem. It works fine
now.
thanks anyway
