Hi Alan, its the Intel ICH4 chipset, I've tried it on 2.4.21-pre5-ac3 too,
to make sure its not something funny in the 2.4.21-pre5-gss kernel, same
problem occurred.
I've attached the lspci -vv output, and the /proc/ide/hda/settings file.

On further investigation, I do get valid results on /dev/hdb, but i can't
get /dev/hda (the WDC WD800JB-00CRA1) to give me sane test results. i've di=
sabled
S.M.A.R.T. in the BIOS, done a cold boot, and not poked at the drive at all
with smartctl before running hdparm, and i still get the invalid results:
/dev/hda:
Timing buffer-cache reads: -3008 MB in 0.00 seconds =3D -inf kB/sec
Timing buffered disk reads: -1504 MB in 0.00 seconds =3D -inf kB/sec
Hmm.. suspicious results: probably not enough free memory for a proper test.
/dev/hdb:
Timing buffer-cache reads: 128 MB in 0.27 seconds =3D474.07 MB/sec
Timing buffered disk reads: 64 MB in 1.40 seconds =3D 45.71 MB/sec
I can't feel a noticable difference in speed for hda though.

in the beginning, was the code.
