Driver question. How does one convince Sys. V/AT that we want to write into PHYSICAL memory. (I/O space for example.) I want to write into video memory for a graphics driver at 0xb0000. I tried: char *base_ptr; ....stuff.... base_ptr = gstokv(VIDEOSEL); But this is wrong. What is the correct way? [From John Antypas, gatech!petro!mercy!ucrmath!soft21!root]
