NT4 was heavily used by businesses due it's stability and better interface compared to previous versions and support ended in Dec 2004, although businesses could pay for support past that date.
Windows 2000 was the new and unproven and SP2 wasn't released until mid 2001 although I seem to remember SP3 being a thing to wait for.

Keep in mind that XP wasn't deemed stable and suitable for business use until at least when SP2 was released.
I don't know about the 9200 but I do know the 9600 and 9700 does have NT4 drivers that work so if you can't find one specifically for 9200 or "9000 series" you can likely modify the below.
I haven't used the 9700 in a long time on NT4 but I use the 9600 frequently in my HP n600c.
ATI NT4 drivers can easily be identified by the "NT4_INF" folder name in the "driver" folder.

There is also this driver but I've never tested it since I've never had those cards and I never tried to see if I could get it working with 9600 or 9700:
