If anyone, or the author, could please E-mail me, or repost
the article on reverse engineering the Borland BGI interface.
I would be eternally grateful, I will post any new device drivers
I create with it.
Initially I need one to drive the Paradise VGA + 16 board, but I may do
others.
Thanks in advance.

I have it on good authority that the BGI format description will be
posted on CIS by the end of this month...

I used this skeleton along with a book called "Graphics Programming in Turbo C 2.0" and have successfully created a BGI driver for the following modes 320x200 256 colors and 640x400 256 colors The only thing I can't figure out is how to handle requests to print in the default font ( any other font will work ) At this point I can run the whole Borland supplied BGIDEMO program if I change it to use fonts other the DEFAULT_FONT. When I get the whole thing working and polished (or I give up) I will post it. An interesting foot note is that when I called Borland and asked about the book I found out the information was printed without permission and they seemed really touchy about the whole subject. One more thing. If you get the book it won't do you much good without the BGI skeleton that was posted a while back. Plus there are a couple of errors in the book that will keep the whole thing from working. (In order to understand the following, you must have the book and the skeleton) 1. There is another vector between TEXTSIZ and FLOODFILL, the book forgot it. I don't know what it does but it must be there and and it needs to point to NOP_01 2. The SETBITMAP/RESTOREBITMAP input variables are not what the book claims. I don't remember what they really are right off hand. I CONCLUSION, EVEN WITH THE BOOK AND THE SKELETON, FIGURING IT ALL OUT IS FFFAAAAAAAARRRRR FROM EASY. I'VE SPENT HUNDREDS OF HOURS MAKING IT WORK (HALF THAT WAS REBOOTING AFTER IT HUNG THE SYSTEM). BORLAND HAS REALLY PISSED ME OFF BY NOT RELEASING THE INFORMATION VOLENTARILY. I AM LOOKING FORWARD TO GIVING OUT MY EXAMPLE. WITH IT, YOU CAN MODIFY IT TO WORK FOR ANY GRAPHICS MODE YOU DESIRE FAIRLY EASILY. sorry I rambled. -- Gene Lee UUCP: ...!amdahl!ems!minnow!lee Unisys Corporation Phone: +1 612 635 3993 CSNET: lee@minnow.SP.Unisys.Com If not for the courage of the fearless manager, the paycheck would be lost.
