1. use_vesa(1)

Now that I'm using a machine with an ATI graphics card,
I'm wondering if maybe use_vesa(1) should be the default.
It's necessary for a lot of cards in SVGA modes.
The thing I'd like to determine is whether there's a
downside to making it the default. WATCOM provided
very little documentation about it.
Can anyone tell me if use_vesa(1)
causes a problem with their graphics card?
Try any graphics program that runs
in SVGA  (mode 256 or higher)
For example, add:
           include machine.e
           use_vesa(1)
at the top of demo\dos32\mset.ex in Euphoria 2.2.
mset runs in mode 261.

Thanks,

No problem on an eMachine (with ATI chipset, I think, & Eu2.1 ); in fact, as
intended, with use_vesa(1) the mset.ex now displays properly on it.

Here is how device manager under 98 SE2 describes my video card:

Class: Display adapters
       Device: Trident Blade 3D PCI/AGP (v6.50.5452-11a)
       Resources:
         IRQ: 11
         I/O: 03B0h-03BBh
         I/O: 03C0h-03DFh
         MEM: 000A0000h-000AFFFFh
         MEM: 000B0000h-000BFFFFh
         MEM: DF800000h-DFFFFFFFh
         MEM: DF000000h-DF01FFFFh
         MEM: DE800000h-DEFFFFFFh
         MEM: 000C0000h-000CBFFFh
         MEM: DF020000h-DF02FFFFh

I ran MSET both with and without your code and the Mandelbrot set displayed
cleanly. ESC did not get me out cleanly, but this problem was common to
both sets of code. The card has 8mb of SDRAM and is set under windows
to run at 1024x768 True Color(32 bit) on a 15" Maxtech monitor.

I would really like to see the results on a v7700 or some of the new
geForces.

Tried it both ways with a Diamond Viper V330 (Nvidia Riva 128) 3D 4MB AGP.
No problems with or without use_vesa(1).

In my Toshiba 7010 Portege (laptop with TFT screen, WinNT) works properly.

This is a point I mentioned some time ago. Maybe you could put it in the
documentation?

Doesn't matter if I use use_vesa(1) or not, it runs anyway with my
Matrox Millenium G200LE (8MBSD).

Have a nice day, Rolf
