Im getting problems to get the DVD burner in udma4 mode. It says:
ata1-master: DMA limited to UDMA33, non-ATA66 cable or device
This is wrong, the device is udma4 capable.
The problem seems to be in the detection of the cable type, it detects it as
40-pin, while its a 80-pin one. (dmsg is at the end)
* The DVD is secondary master, with no other devices on the cable
* THe bios detects it correctly, on boot screen it says udma66
* When booting in w*n, it says udma66
* I have another hard drive udma100 on same system, so I inverted (identical)
cables, and the HD is still at udma100, this to discard any cable problems.
Its important to get udma66 working, in order to achive maximum burning speed
for the drive.
So i'm out of ideas here, and any help would be apretiated.
Thanks in advance :)
Here is the (relevant) parts of dmesg:
