I dived into this yesterday - Seems like something is really broken in
hardware (at least with me). I got the iwld interrupt IRQ7 even with just
the at-bus controller and the vga installed. It went away
a) when you unconnected the harddisk (well, no solution to me)....
b) when you used another, 8 bit vga (occured rarely, though)
c) when you used the original vga in an 8 bit slot (occured rare, too)
BUT: Adding some more boards (i/o, soundblaster et al) made the situation
worse and worse, no matter what boards were used. Also, with the original 2
board setting, both boards don't connect ANYTHING to IRQ7 (this is pin B21).
So I've decided I'll blame a bad termination for now. But I still wonder -
IRQ 7 worked somed time ago.....
I've posted about this to an ibm-pc hardware group. Maybe they'll know
