If you cannot not use ANY interrupts, you will have to make your own fonts
and draw them, pixel by pixel.

An easy way to get fonts is boot up dos and copy the fonts in the BIOS roms.

Some sample code to read fonts from the bios, under dos from a standdard
vga, is in in common.zip at
http://users.uniserve.com/~alexad3

The same site has a dos programming course that covers fonts in graphics
modes.
