VESA under FLAT/UNREAL mode with PB 3.5

[Gunther]

Manos,

I thought that VBE supports graphics for linear frame buffer above 1 MB.

Manos.

that's right. You can use it in FLAT mode. The archive vesaflat.zip contains an example.

Gunther,

Your example SetSVGAPixel is familiar to me.
I am interesting for BitBlt and lines, but without use pixel by pixel.

Manos.

[Gunther]

Manos,

that's the point. There's an old book from Microsoft Press: Programmer's Guide to PC Video Systems by Richard Wilton. It contains old DOS examples for line and circle drawing (Bresenham). Another source could be Mike Abrash's book, which can be downloaded by Dr. Dobbs. It's about VGA, but the ideas can be used for the LFB, too. I hope that helps.

Thank you Gunther.

Manos.

yes, of course. It contains also procedures for different Mode X resolutions.

you can find Mode X stuff in PDF form, on the web

do you have the newer version or the older one (pictured) ?

what i liked about it - it was a full reference on VGA registers
and - it had some code, too - that could be adapted to 32-bit

Hi Dave,

   I have the newer edition in hard copy and the older as a text
file.  And both come with the code, new on a diskette and the
older as a ZIP.  Fun stuff.

   For Mode X, I have a PDF of Micheal Abrash's "Graphic
Programming Black Book".

Cheers,

Steve

to be honest, I've the German translation (second edition) from 1994. There are pictures inside.

You're one of the lucky ones. I've the source code on a diskette, but no appropriate drive. :(

Hi Gunther,

   Well, if you need it, I am sure something could be worked
out.  I will see if I can find a link to the older files.

that would be fine.

Hi,

   Found the link to the older files.

http://alexfru.narod.ru/emiscdocs.html

Look for "VGAGUIDE.ZIP" and "VGAG-SRC.ZIP".  If you want the
newer source, you can send me an e-mail address or the like.
As you have the book, I am assuming it is okay to send you the
source files.  They do differ a bit from the older edition.

Cheers,

Steve N.

Steve,

thank you for the link.  :t I'll send you a PM with the mail address. One question: What's a CHP file?
