DMA Transfer



I installed version 3.1, and got some error related to
DMA transfer on HDD. but the system works well.

The question:
   Is it on Ultra-DMA mode 3?
   or
   Is it on Ultra-DMA mode 2?
   or
   Is it without Ultra-DMA mode?

Here is a part of dmesg:
wd0c:  aborted command, interface CRC error reading
fsbn 0 (wd0 bn 0; cn 0 tn 0 sn 0), retrying
wd0: transfer error, downgrading to Ultra-DMA mode 4
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 4
wd0c:  aborted command, interface CRC error reading
fsbn 0 (wd0 bn 0; cn 0 tn 0 sn 0), retrying

wd0: soft error (corrected)
