Hi !

I'm trying to transfer an old machine (chipset Intel FX + Ciryx P166+ ) to a
more decent hardware.
The new motherboard is a Gigabyte GA-5AX (rev 5.x) associated with a AMD
K6-2/500. In the documentation, they said that the controller understand the
UDMA/66 mode.
Here is the dmesg :

>NetBSD 1.4X (MARGO) #0: Fri Apr  7 19:55:43 CEST 2000

>wd0(pciide0:0:0): using PIO mode 4, DMA mode 2 (using DMA data transfers)
>pciide0: secondary channel configured to compatibility mode
>pciide0: disabling secondary channel (no drives)

But when "using" (in fact, just trying to do fsck -y), I got theses messages
over and over :

pciide0:0:0: lost interrupt

pciide0:0:0: bus-master DMA error: missing interrupt, status=0x21
