For my own personal reasons, I decided to get an ISA SCSI-2 card for my Pentium computer. It’s a DTC 3520A. I finally got a couple of SCSI devices and when testing them out, I got the following error message from the onboard BIOS
“Host adapter failed in interrupt channel test”. It’s preset for IRQ 11, but when I tried IRQ 10, I got the same thing.
When I boot into Windows XP, it doesn’t know what driver to use for the SCSI controller. According to a readme file on the installation disk it says that the Windows 95 and NT driver is Adaptec “AHA-1515/AHA150X” but I can’t find a driver that will work with XP. I can’t find that particular driver, and when I chose a more advanced driver from a list XP gave me, it didn’t work.
So, my questions are
What’s the normal cause of an interrupt channel test failure?
I don’t have a hard drive hooked up, just a CD-Writer and a zip drive, is that OK, or does a SCSI controller really prefer a hard driver hooked up?
The SCSI card, is set to 7, of course, the zip drive is set to 5 and the CD-Writter is set to 4. That means that I’d set the termination for the Zip drive, but not the CD-Writer, right?
I know that there’s a million reasons why I shouldn’t have gone with SCSI-2, but I’m comfortable with the choice I made. The only thing I might change is getting a new card if I can’t get Windows to recognize it. Although I don’t know if I should go with another SCSI-2 card (ISA or PCI), or go with a new card, and get an 80 to 50 pin adapter.
Anyway, Thank you in advance.
