I was working on trying to get this box to turn on DMA for the drives and we 
get an error:  We used the stock 2.4.18-3smp kernel from redhat 7.3 and also 
2.4.19 from source.  The motherboard is a dual P4 tyan, I didn't catch the 
model number.

We double checked the DMA settings and enabled an ugly hack (their term), 
still no go.  From what it looks like, there is something with the ide 
controller at boot time that prevents the kernel from being able to set DMA.
