Folks, does anyone have experience with early Compaq VGA card from 1987 with PVGA1A chip?
It works, but if it's in the system, IDE controller doesn't work. I checked with Compaq multi-io card in a Deskpro 286 and with XT-IDE controller on a generic 286 motherboard.
I suspect this is because it uses IRQ 14. There are no jumpers to disable IRQ.
Anyone have any experience with this card or any PVGA1A cards?
All other VGA cards I have work just fine with IDE controllers.
