I was replying to Jerome who is the original author of the Pascal one.
I get that VGA is widely available. I'm writing a library, so I want to
support as much as possible. My intended targets (in the order of
planned implementation) are VGA, VESA, CGA, and EGA. I want to have
contained tests for each of them (and separate for different VESA modes,
but I already have a document on doing that) so that an application
could list to the user all the supported modes for their hardware.
Happy Hacking,

Hi David,
The EGA check does not come back positive on my VGA machine.
Is this expected?
We suggested several: Do you mean the Pascal one suggested
by Mark, the PC Mag one suggested by Mateusz, or the ones
suggested by me? If all of them, then I would say NO, this
is not expected. If SOME of them, then I suggest that you
simply use those which work ;-)
Also, I think it is sufficient to have a good VGA test:
Only weird people like me still have EGA boards in some
dusty cardboard boxes. So you could say "either use VGA
or fall back to text mode" without risking much harm ;-)
Regards, Eric
PS: Does anybody know a computer museum? I know people with
way more exotic stuff who would be interested to SELL some!
