As long as you had access to a library... When I was 14 or so, I used the MS-DOS DEBUG program to run step-by-step an executable that did something to change blinking to high-intensity background in text mode. After one hour or so I found the magic BIOS call... which of course was documented in the technical manual I found in the library one year later (because new school = new library with more books).
- z500 3y agoWhen I was a kid I used to have this Charles Petzold book that I learned this stuff from, it was basically my Bible. I don't have it anymore, I wish I could remember what it was. People recommend Code a lot, but I don't think that was it. Edit: it wasn't Charles Petzold at all, it was DOS Power Tools by Paul Somerson
