If the STB VLB24 is an S3 805, then they are probably not mapping the entire video ram into memory due to limitation in the *BSD twins. Supposedly, this limitation of mapping a high physical address,e.g., 0x7c000000, to a user process has been fixed in 386bsd 0.2. On the linux front, the are capable of mapping the entire video ram of an S3 805 card to the user process;whether this made into the XFree86-2.0, I don't know nor I care :-) Amancio -- This message brought to you by the letters X and S and the number 3 Amancio Hasty | Home: (415) 495-3046 | ftp-site depository of all my work: e-mail hasty@netcom.com | sunvis.rtpnc.epa.gov:/pub/386bsd/X
