A8V Deluxe: No DMA on Secondary IDE port

Hi,

I have following storage devices connected:

SATA 1: HD1
PATA Primary: HD2 (Master)
PATA Secondary: CDROM (Master), CDRW (Secondary)

The problem is, that if I enable DMA on the secondary IDE port, I cannot
read any CDROM! Either I even cannot acccess a CD (Windows 98) or I can
access only few files (Windows XP SP2). If I switch off DMA (using only
PIO mode), everything works (but slow and with high CPU load).

I've tried to switch the IDE cable (80pin, 40pin) but without success.
Mainboard drivers (4in1) are installed.

Any hint? Or is my motherboard defective?

I'm having the same problem but with only one drive on the secondary, my
4xdvd-r, dvd reader are good but my 16xdvd-r locks up the post until I
remove it (it runs fine on other pc's)
