A way, yes. Easy, depends on your point of view. First, have the new font somewhere in your program. It's stored as one byte per scan line per character. You may be able to get a font editor to output this. Move the font into DOS memory. Depending on its size, it may fit the transfer buffer, or you can use __dpmi_allocate_dos_memory. Then use dosmemput to do the move. Then, do an INT 10 with: - AX = 0x1100 - ES:BP -> your font in real-mode memory - CX = # of characters to load (256 for all of them) - DX = character to start at (probably 0) - BL = which block to load (0) - BH = bytes per character (16 for 8x16 font, 14 for 8x14, etc) You can put it back with INT 10/AH = 0/AL = 3, or do textmode(_CO80) after #including Source: Ralf Brown's Interrupt List R53 HTH Nate Eldredge eldredge AT ap DOT net
