Before SP2 I couldn't run Win2k on my computer. There was incompatibilitys with the VIA MVP3 chipset and Sound Blaster drivers that use the digital out port. After seeing that these two bugs were fixed I decided to try Win2k again.

I did a clean format on my C partition, and installed Win2k. I then installed Win2k, then installed SP2, and the March 2001 Compatibility update. Everything works fine, the computer doesn't lock up in 3d games anymore.
