I'm having the same problem with the high resolution graphics mode. I want to access the EGA without using interrupts; so my strategy was to essentially imitate the interrupt 10 mode selection and WRITE_DOT routines (I'm using PASCAL). To my chagrin, nothing appears on the screen. Any hints?

It covers the mechanics of how to put dots all over in all the current modes CGA,....,VGA plus some non-IBM standards, Hercules... The book has routines in asm which will do the dot putting so you don't have to write up your own, even comes with a disk of them if you want to pay for it, the book also covers various methods for drawing lines, circles, fill algorithims, and mixing text and graphics.
