How do you set text modes like 80x43, 80x45 and 80x60?
I've read Ralph Brown's interrupt list but there are no such modes listed there that work on all video cards.
IDEs like Borlandc's BC and DJGPP's RHIDE use these modes, so there's got to be a way. In RHIDE the 80x43 mode has number 0x503 (I think). With int 10h ah=0 you can only set
modes 0-0ffh. How does RHIDE set that mode? (It must be mode numbers. Mode 80x25 has 0x3 just as usual.)
If there are no ordinary modes, can I tweak the vga regs to get these resolutions?
