When I send out patches for the very, very first release of X11R5 for 386bsd 0.0 it included patches for i/o bitmap permissions . all it needed back then was an ioctl to set the i/o bit permissions. I hardwired the i/o bit map to allow access to the vga registers. The i/o bit map permission was abandoned later on due to S3 chipsets sparse i/o ports numbering scheme, 2ae8, bee8, etc.. And other kernels having difficulties with such a large i/o bitmap :-) 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/incoming
