I am new to this forum, and I hope I am puting my post in the correct location.
Recently I fitted a new AD7543A device, to allow my A30 laptop os win xp sp2, to burn DVD.
After fitting the device to the laptop, I discovered the burning speed was very slow.
Having read several posts I finally managed to get the secondary ide interface that connects to the burner to accept udma.
My problem now is how do I get the primary (hard drive) ide interface to change from pio transfer mode to udma. I have followed several ideas i have found in the forums, all to no avail.
I would much appreciate any help and advice on resolving this problem.
