Upon boot, one sees "ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx". But upon reading e.g., http://storagereview.com/guide2000/ref/hdd/if/ide/modesUDMA.html one feels their computer sounds more like the 100Mhz kind. How can one tell if one is taking full advantage of the hardware? Maybe I am, as I see "IDE UDMA100 controller" in dmesg etc. output (that I put in http://jidanni.org/comp/system.zip)
That's the PCI bus, not UDMA etc. Unless your hardware is broken or miscovfigured, you're not using PIO. PIO is CPU-intensive, and you really orght be using DMA. And probably are.
