I am finding this to be true with S3's 911 and the S3 801 which is %50 faster than the 911. However, the 801 has added functionality like 64k colors at a 1024x768 with 2MB. The distributed XBSD8514 server was compiled with gcc-1.38;additionally, it was not compiled with all the optimizations. I intent to release a server compiled and optimized with gcc-2.3.1. We should get a %20 improvement. > >>Furthermore, you have to use DOS to setup a 1024x768 NI mode. > >This is not, technically, a lie; but it is intentionally misleading. >You do, indeed, have to use DOS to set up a 1024x768 mode. >That mode is the 1024x768x60hz mode.

The stock svr4 is incapable of accessing registers beyond x3ff without modifications. There is a patch with the latest release of XFree86 to allow you to access the 8514/a registers as well as, the S3 registers. >c Amancio Hasty
