Thread: Isa 8bit Back Plane issue

    Question Isa 8bit Back Plane issue

    Hi Guys

    I am having a issue on a isa backplane,when i put a realtek rtg3105 vga card alone it doesn´t work,but when i insert a sound card next to it the vga card boots on the system.

    Could the vga rtg3105 had a line issue ,something like iochrdy line not attached or something?

    Best Regards

    What's the system? (i.e. are you trying to stick something into slot 8 of a 5160?)

    Hi Chuck

    No is a passive isa backplane on a olivetti prodest pc1 floppy version.
    Strange because vga gets back light but only boot to screen when the sound card is inserted on the backplane .

    Even with lo tech isa xt-ide the vga dont boot....
