Ok I tried it .

Geforce 4 Ti4200
P3B-F BIOS 1008F.004
512MB RAM
AWE64 Value
Pentium 3 1GHz at 750MHz (100MHz FSB)
SIl3114 SATA disk controller
1TB SATA hard drive
IDE DVD-ROM drive
PS/2 keyboard
USB mouse

Windows 98 SE with Directx 9 , sesp21a-en.exe and U98SESP3.EXE installed

No issues whatsoever with video playback and quick battle mode in Bridge Commander at 1600x1200 70Hz .

EDIT: Forgot what Nvidia driver I'm using, will check tomorrow. Going to bed now .
EDIT2: That was using Bridge Commander 1.0 , no patches installed .

Thanks for testing! Makes me wonder now if I should put the P3 in with the Geforce3... My only reservation is keeping good DOS compatibility...
