possible to enable udma133?
 
I have an Aopen ak79D-1394, running redhat 9 with kernel 2.4.20. I got everything working, but my IDE shows only udma100 but the board and the hard drive both support 133. Is there anyway to get 133?

I checked the kernel source code and it looks like there's only support for 100... is there a patch?

Well, if the RedHat kernel doesn't support ATA/133, there's nothing stopping you from going to kernel.org, grabbing the newest development kernel, compiling it, and then using that. I'd be pretty surprised if there wasn't ATA/133 support by now.

And, no, there's pretty much zero reason to move from ATA/100 to ATA/133, so I doubt many people have bothered.
