today i brought my 3 week old FX001D w/ 8-bit interface card
back for a check. i finally gave up after testing with various
driver versions (all MSCDEX, MTMCDAE and MTMCDAS), settings and
CD-roms. i had lots of problems. the MTMCDAE driver with option
/t:s worked best for me, but i still had lots of trouble.

cdbench reported 
* unable to detect size via IOCTL
* problems with larger jumps
* unable to verify disksize

cdbench didn't work at all with other settings than the above
(didn't recognize cd-rom).

different audio-cd-players refused to play or hang while setup.

lots of CDR101 drive not readys

system hangs after random time

cd and dir caused cd to rootdirectory of cd-rom (on SB pro demo CD).

no drive detection in about 5-10% of cold boot and 80-90% of warm
boots.

i'm 100% sure that i have no IRQ DMA I/O conflicts but as i said,
DMA mode didn't work at all. i'd like to know if the IOCTL warning
from cdbench means anything. the drive usually scanned half the cd-
rom and then stopped with this message (a dejusted laser maybe?).
seems like i have no 600+ MB cd-roms (rebel assault? corel draw 4.0
rev c? cps SB pro 4.0 demo? a game compilation?) but after that cdbench
reported an average access of about 205ms (peek was more than 1500ms!)
and about 307000b/s data transfer rate.

i have no trouble HW in my system, the only other stuff is a 
sb pro 4.0 and a tseng et4000 card. the latter one sometimes screws
with the colours (wrong pallette), but that's the only problem.

i'm curious about the results from this check...
