I need help for my new Toshiba satellite 1620.
The problem is:
"graphics modes 256 to 261 don't work. I see everything comressed in the =
upper part of the screen".
I use DOS 6.22, Euphoria for DOS 2.0 (but 2.2 works the same). The =
notebook is equipped with CPU AMD K6 2-3d 475 MHz and 32 MRAM, graphic =
adapter is an ATI rage lt pro.
Toshiba does not support this PC in DOS, so I steel can't find an audio =
adapter (thanks Toshiba...), but I found a DOS graphic adaptor in ATI =
website wich should be OK for this graphic adapter.
I installed it, and I found:
a.. my flight simulator now works well if I run it as if I had a "vesa =
1.2".
b.. Euphoria mode 259 seems to work better (I read text more clearly) =
but I steel see everything compressed in the upper part of the screen.
An ATI utility says that graphic adaptor and LCD screen works up to 800 =
x 600 mode.
I tried to use "machine.e" library and the instruction use_vesa (1) =
without any result.
Of course the same Euphoria program works well when run on another PC.
Can someone help me?
Thanks
Franco

2. Re: video adapter problem
I believe what might be happening, is that the ATI chip does not
automagically scale video to fit the LCD, but that there are special video
modes available for that instead, that Windows and the BIOS would use by
default. Thus, when a game in DirectX calls for 320x200, it selects a
scaling video mode so that it fills the 800x600 display, otherwise it would
only fill the top 320x200 portion of the screen.

Hello Franco,
The vesa drivers are written by the video chip manufactures
so who ever made your video chip set in the laptop is the only
place that you can get drivers from.
Here is some information on toshiba web site
http://www.toshiba.ca/support/Tsbs/200/tsb0235.htm
If your laptop has a external video connector so you
can connect a external video monitor, that would tell you
if it the problem is to do with the fact that the built-in
LCD monitor is a dual-scan monitor and that may not work
with the drivers you have.

4. Re: video adapter problem
Franco,
My advise is to start exploring the Windows platform for programming.
The advantage over DOS programming is 1000x better. Its also clear that
a lot of new things arent compatible with DOS, so you will probably end up
reprogramming anything you do in DOS in the future anyway. Disk access is
faster in Windows also.
You might have to learn a few additional programming techniques, but it
will be worth it in the long run.
Good luck with it.

5. Re: video adapter problem
OK, I think I'll do as you suggest beginning from the next project.
Thanks
