MOTU PCI324 vs. 424

[Don]

Hello all,

I used a MOTU 2408/PCI324 along with two 1224s for years, until the
mobo gave up. The replacement system (Soyo SY-TISU, PIII-1GHz, Intel
815EP chipset, U160 SCSI hard drives, Win98SE, 512Mb) has never played
well with the MOTU stuff - cranky about shutdowns, frequent blue
screen of death, and other issues that have given considerable grief.
A clean install results in a rock solid system with no issues until
the MOTU stuff is added, so I'm pretty much convinced that they are
causing the problems.

I considered upgrading to Win2K Professional (with all the tinkering I
do, I absolutely refuse to use XP for obvious reasons), but am
hesitant to do this for fear of introducing more problems than I
already have.

Any experience out there with the PCI324 in a Win2K system? Has
anyone using Windows "upgraded" to the PCI424 with good results?
Since MOTU tech support seems totally Mac-oriented, should I just sell
the MOTUs and go with M-Audio or someone else that's more committed to
the Windows platform? If so, any suggestions?

Thanks in advance...
