Lines: 18 From: Joel SeiferasI randomly tried some invocations of the new EGA's interruption 10H. Function 0 now has several new modes. Without an enhanced display, of course, I could not observe most of them. Modes 13 and 14 (decimal), respectively, are for 320 x 200 and 640 x 200 graphics, using a font from a new place. Mode 15 is for 640 x 350 graphics on the IBM monochrome display. Old mode 6 has been enhanced to provide color. There are also new functions. Function 16 (decimal) has something to do with screen attributes, at least for mode 15. Function 17 has something to do with changing fonts, at least in monochrome text modes. Code 1 gives an 8 x 14 font, and code 2 gives a 9 x 8 font. The latter will be useful in 43-line mode on the monochrome display; but I can't find how to get to that mode, and the diagnostics do not even show it. Joel Seiferas
