I have run across a nice reproducable bug. If you run the PC Mag Windows
Benchmarks version 2.0, and run the BitBlt ROP test, the system will stop
displaying about half way thru the test. My hardware configuration is: 486/50
symphony chipset motherboard with 256k cache/16 MB ram, video seven vram ii
running at 1024x768, Logitech series 9 mouse plugged into a Microsoft InPort
card, 2 x 200 MB IDE disks, 1 Adaptec 1542B SCSI controller with a Maxtor 1.2
GB disk, a Sony 541 CDROM, and a Archive Python DAT tape. Other boards in the
system are a Western Digital 8013EBT ethernet card, and a Media Vision ProAudio
Spectrum 16. While running the benchmarks, one of the test bitmaps will be
displayed partially inverted (or very wrong colors). A few ROP codes later, the
mouse stops responding. If you move the mouse, there is disk activity on drive
C: and then later, event log entries say the mouse has an overrun. I have also
seen the system crash with the whole screen displayed in inverse colors (or
something very wrong). The system runs Win 3.1 just fine. Anytime you get a
8514 or S3 driver in stable form, feel free to share it with us. - Jan
