Intel-based motherboard

Hello -=-
I know it's considered poor practice to just post to a list but I
have a question which I and others have been unable to solve relating to the chipset on my motherboard.
I have an Intel 845PE-based motherboard in my Dell 4550 purchased
last May. I've been running LINUX on it for about 2 months now and I like it a lot. Interestingly enough, even with DMA enabled, performance from the HD, CD-ROM, and CD-RW sucks! For example... writing a 650M CD takes nearly 45 minutes on my 40x burner. Copying a few hundred meg of data from one partition to another on the HD took nearly an hour and a half. When I try to watch a DivX movie or one of the movies for q3 or Diablo 2, they skip and get out of synch. I've included some information about my system which may be of help.

again, I post to the list as a last resort because if I can't get this working, I'll have to return to using m$ software. Thanks in advance for any help!

What are the ide settings on the various devices? Can we have the
output of hdparm -vi, hdparm -d, and hdparm -t on each device? What kernel are you using? My guess is you are are not using dma. Try the latest 2.4.22pre kernel.

Once you have their hardware. Never give it back.
