The chipset for the board is the ali m1541 and i've downloaded the latest drivers, 2.05 from ali's website. I'm using windows 2000, i've tried the harddrive as master and the lg dvd as sec-master, i've also tried them on the same cable, it doesn't seem to make a difference.
At first when the drive was in ultra dma mode you would open my computer and see the name of the cd, but the icon would always be generic, it wouldn't have reconginzed it was a dvd, and when you went to read the drive you got an "... i/o device error" you had to take the dvd out of the drive and restart before you could read any disks.
On the advice of another post here i removed the drive, and the controllers from device manager and had them reinstall themselves, that worked in the sense that now i dont' get the "i/o device error messgage" the icon on the cd rom changes to the powerdvd one and i can explore the cd itself. It's just when i actually launch powerdvd and try and play the dvd that it freezes, or when i try and launch nero and it's "scanning for recorders".
I tried an 80 pin cable and the hdd worked fine, but when i connected it to the dvd as well they both failed, as did the dvd when i connected the 80 just to it, right now i have both the dvd and the hdd on seperate 40 pin cables as there was no advantage in using the 80 pin, i was just messing around by trying it.
