Do a search for demoscene. Tons of small programs that do all kinds of interesting things with video and sound. A huge number are written in asm. A lot of it's in dos and a lot are boot disks

Huuuge Google link
I did a search on Google ("16 bit VESA assembly") an I found this: http://www.astahost.com/info.php/Vesa-Programming_t3849.html and this: http://www.astahost.com/VESA-Programming-t3849.html&p=49359#entry49359 and this: http://www.daniweb.com/software-development/assembly/threads/359724 Something to look at also: http://en.wikipedia.org/wiki/VBE Or ask mbr_str ? 
EDIT by DOS386 : fixed absurdly long link (broken anyway ???) |

1. You did read the FAQ on the top ? 2. http://board.flatassembler.net/topic.php?t=9738 3. If you want to stay in RM then you need BS ... no access to the LFB 
4. Don't use hardcoded fixed mode numbers, do search (except if VESA is < 2.0 maybe), see [2.] 5. Don't use only too high resolutions (support down to 800x600 at least, better 640x480 too) 6. Support both 32bpp and 24bpp (most VESA's don't have both) _________________ Bug Nr.: 12345 Title: Hello World program compiles to 100 KB !!! Status: Closed: NOT a Bug |

I use the 16 bit unrealmode instead. Quote:
The native resolution of my 28" lcd is 1920x1200 and all other resolutions will be interpolated and result an unsharp view. So i am glad that my colorfull gtx 295 video card provide this resolution in the vesa modelist. Quote: 6. Support both 32bpp and 24bpp (most VESA's don't have both) I do not like 24 bit modi and i can not understand why this modi exist on modern video cards and why those modi in use today. This make only sense on very old video cards with less video ram below 4 mib. Dirk |
