RE: nonsense C/H/S values for CF (used in ide)

hmm, you mean there's an additional patch to ide.c, which is already used to
build linuxBIOS, not in the source tree?

thanks,

The kernel pci-irq code refuse to setup IRQ for VGA devices. You have to
set it up yourself. BTW, your card still need some init code in your VGA
BIOS.

wow. That's an old one.

I realize this may not fix the problem, but I would still recommend you
move to 2.4.18 or 2.4.19. Much better.

The card has problem is not a VGA card. It's a 2-channle-video-capture-card.   There is no problem with
1-channel-video-capture-card.
