First post, by Grandiloquence
First of all, hello, I'm Chris. This is my first post here despite lurking for several years and enjoying the varied discussions about old PC tech!
I was hoping that someone may be able to help me out with a question regarding an industrial PC I'm attempting to set up.
I have 3 backplanes, 2 are passive and one is active.
In the ISA slot I have a 486 based board which doesn't have video output.
I have placed a PCI Matrox graphics card in one of the PCI slots. The ISA board emits a couple of beeps, the kind that tell me the settings are wrong as the RTC is dead. I get no display on the monitor.
I know the graphics card works as it was tested on another computer.
This happens on all three backplanes.
Am I on a hiding to nothing here? Have I misunderstood how the pc is set up?
Thanks in advance.
