We cannot because:
1) vga BIOS often uses main BIOS for some things,
2) vga BIOS is a 16bit code and AROS uses 32bit code (first 4 kb - the
bootsector and setup file are in 16bit)
3) We have destroyed BIOS area in memory because we keep there other
4) calling ANY bios (16 bit) would destroy multitasking and slow
performance down a lot."

well i accept suggestions, anyway to improve this to take use of bios
(openbios) ?

thanks in advance,
