In response to some suggestions I give
more for the record on my problem of getting
ata100 transfer rates:

"hdparm /dev/hda" gives:

/dev/hda:
 multcount = 0 (off)
 I/O support = 1 (32-bit)
 unmaskirq = 1 (on)
 using_dma = 1 (on)
 keepsettings = 0 (off)
 nowerr = 0 (off)
 readonly = 0 (off)
 readahead = 8 (on)
 geometry = 3649/255/63, sectors = 58633344, start = 0

so 32 bit mode and dma are indeed on... and still 11 MB/s.

Thx for all the suggestions!
B.D.
