Advice on Cluster Hardware.

[Donald B. Kinghorn]

You can take care of this by adding ide0=ata66 ide1=ata66 to the Lilo append 
line. It forces the udma mode 5 bit and seems to work fine (you get full mode 
5 so you don't need to use ide=ata100 although that may work to ??). I've 
been doing this for several months now on Tyan boards and haven't had any 
problems ... I found this by reading the kernel ide source code ... use the 
source Luke ...
I think there are some other ways to take care of it too, like a kernel patch 
or tweaking things in a custom kernel build ...

I've tried the AUSU dual athlon and yes there do seem to be some problems. 
The first is that 2 out of 3 were DOA ... I've just received 2 more so hope 
if was just a fluke ...  The guys over at 2cpu have some info about the board 
if you want to pop over there and search around a bit
