Sadly, I'm not finding any HDParm numbers from KT133A/686B users with ATA100 drives (and the KT133/A bugs put a wrench in that thought, too.)  Still, look at these numbers from the 2.4 kernel era, with good, standard hardware... they 'suck!'

I got interested in the numbers for my system, and at first found them despicably low (around 4.5 MB/s for the buffered disk read). I have been using the system for well over a year, and never really noticed this very low value... Duh. Turns out my 2.4.18 kernel did not support the VIA chipset in my PC; I could not even enable DMA manually. So one upgrade to 2.4.26 later, I see 272.34 and 50.00 MB/s on the one hard disk, and 261.22 and 40.00 MB/s on the other. I am genuinely impressed :-). (The system is a KT333/8235-machine, by the way.)

Some people say that cats are sneaky, evil and cruel. True, and they have many other fine qualities as well.
