Not clear if you're asking about the disk or the network card.  When
I repeatedly run "hdparm -t /dev/hda", I see numbers like this:


 Timing buffered disk reads:  64 MB in 36.56 seconds =  1.75 MB/sec
 Timing buffered disk reads:  64 MB in 26.79 seconds =  2.39 MB/sec
 Timing buffered disk reads:  64 MB in 31.40 seconds =  2.04 MB/sec
 Timing buffered disk reads:  64 MB in 26.54 seconds =  2.41 MB/sec
 Timing buffered disk reads:  64 MB in 26.96 seconds =  2.37 MB/sec

This drive apparently has no DMA modes.  Increasing the multcount
value has no effect.  I get similar numbers with this drive in my
old Dell Lattitude, so I guess it's just a slow drive.

Yep.  I's not a show-stopper, but it's not good either.  I tolerate
little glitches like this because everything about my iPAQ is
experimental.

There are several 10/100 cards listed on the compatibility page at
handhelds.org.  How does one tell if a card is "non-CardBus"?
