Legacy ISA Card Read Problems
My machine (CMM or Coordinate Measuring Machine) uses 2 ISA cards. My old Dell Optiplex has 4 ISA slots & they work fine in this PC.
My problem is: I ordered a special build PC with 2 ISA slots (one shared) & 5 PCI's. The 2 boards receive power (lights on the boards are lit), but I cannot get the PC or CMM controller to read or recognize them ("fails read test" is the error I receive when trying to load my controller).
I went into the BIOS & tried each IRQ setting that weren't already in use to no avail. I believe these cards use IRQ 9.
Speaking with others, I have found that anytime a PC was built for their customers with ISA slots for the same cards, they had used motherboards that had 3 ISA slots. Is there some logical reason why the 3 slot boards work & the 2 slot boards don't or is this just a coincidence? Both are P4 socket 478 boards.
The only other difference is that I have Win2000 Pro installed & they had XP Pro. I'm in the process of reformatting & moving to XP Pro.
Any help will be greatly appreciated.
Thanx in advance,
