I have installed CentOS 4.2, recently, on new computer.
Everything seemed to work fine.
However, we've found out that disk transfers are incredibly slow, and I just can't figure out what to do in order to fix it.
Computer is now running CentOS 4.3 (updated it 1 hour ago), and same thing is still present. I hoped kernel upgrade might fix it, but it didn't.
I am having similar issues with an Intel 845 based board. It sounds like your disks are running in PIO rather than in UDMA mode.
Erm, if I'm not wrong, SATA uses DMA 'by default', it's not something we can change.
Thanks anyway :)
