Hi, Thanks, but my question to you is, _my_ RAMDAC *is* supported. What I can't find under "chipset" is the S3 chip that I have (86C805). What is under chipset is s3_generic, mmio_928, and newmmio. The RAMDAC is there. Given that, would your statement still apply? Also, pardon my ignorance, but what is Lo$e3.11? And where would I find it to try it?
