It might be helpful to know the distro you are using. Also take a peak at some of the links here: http://www.google.com/linux?q=Promise+ATA+100&site=sear...
Sorry no first hand experience with ATA-66/100 yet for me. I keep reading it is patchable and/or will be in the new kernal due out (maybe) next month.
i've had the same problems with corel linux version 2... i heard suse supports ata100... but it's not really ata100 that's the problem.. the promise controler seems to need some kind of driver... so... i'm waiting till 2.4 kernel is done and hope that it works
I tried recompiling my 2.2.17 kernel the other day with "other ide card" support turned on, and it worked flawlessly on my a7v... which was good, cuz 2.4.0-test11 forced me to give up aurora on boot (i know... stupid reason.. but I like the purdy piktyers). promise2065... gooood... aurora... gooood... both goooood. ok, I'm done now.
Mandrake Linux 7.2 handled my promise ata-100 controller
in a fresh install with no probs. Performance is much
better, and I am very impressed with mandrakes hardware
detection, but it does take some of the fun out of it.
Getting a linux box installed and configured used to be
a challenge, but mandrake found and installed everything
for me, even my usb printer. wow...
crackdaddy, I was just curious what kernel parameters you used to get the promise controller working. Did you use any other parameters besides the "Other ide card" option? And also, what kind of boot parameters did you use? If you could post this infomation, that would be great as I would like to use that controller in RedHat 7. Thanks.
I have not yet begun to procrastinate.
I didn't use any special boot params, just the other ide support when compiling the kernel. If you don't want to mess with that, go to www.linux-mandrake.com, they just threw a page up about getting linux to work with the a7v board, it's boot parameter only, much easier than compiling the kernel I suppose.
