Hello again, and thanks to Salvador Eduardo Tropea for answering me.
I have tried what SET said but it did NOT work. Even more, I have
realized that RHIDE also gets confused in PLAIN TEXT MODE! (I think
I'm gonna cry....). [Snip]
Sometimes when I do a SIMPLE printf it shows results in the middle of
the source I'm debugging, so have to keypress ALT+F5 twice to get it
ok again (of course that nothing is on the user screen).
Anyway, I answer what SET asked me to see if it helps to solve at
least one of the two problems! Thank to you all (but specially to
SET).

>1) Try calling RHIDE with -G 1
I did but it didn't work (neither -G 2, -G 3, ..., by the way, where
on earth did you find what option -G # means?)
>2) Do you have a VESA card?
Yes, a S3 trio V64+ (VESA 1.0), but also tried a software dirver to
simulate VESA 2.0 extensions.
>3) Are you setting the mode using BIOS?
I'm afraid I do NOT know at all, but if you mean if I called RHIDE
whith -b option, I have just tried (and it still does not work).
>4) Can you install an Hercules monitor/card to yourr PC?
No.

Yes, even the 1024x768x256.

Yes, but there is no *.grd in them.
>3) How did you configured GRX? (board, etc).
No, just did make and used it. Is there any other configuration? I
have found many *.GRD drivers in the djgpp\drivers\ directory, but
NONE OF THEM was a S3 or a VESA driver.
