and what if there is a problem with VESA bios destroying the BP reg.?
looking at the other video routines, BP is often saved there before INT 10h call because of safety reasons..
this would result in some variables having "changed" their values.. (caused by the wrong BP-based addressing..)
I'll take a look. The problems I've seen are caused by sxdots and sydots getting changed in the switch between text and graphics modes. Jonathan
