Sens characters to the screen without BIOS

[Holyman]

HI,

How is it possible to send characters to the screen without using BIOS or any pre-defined functions?

You can write characters directly to screen buffer. AFAIR for 80x25 text mode it starts usually at 0xB800 segment, and each character is represented by pair of bytes (attribute and character). It works at DOS, Windows 9x, never tried it at XP.
