Next186 SoC PC

Hi! Thanks for this core. I've ported it to the MiST board, and did some enhancements, if interested:

(However VGA would need some more care to make it even more compatible - a big topic would be font handling, both in BIOS and HDL, look at SimCity for example.)

Some enhancements

If you modify one line in module "Next186_CPU.V" line 1640 aprox.

Anything like this:
end else begin
	MREQ = 1'b0;
	ISIZE = 1; // jepalza, antes "0", sirve para engañar a algunos programas que detectan CPU y se cuelgan
	IRQ = 1'b1;
end

you can trick CPU as seen by dos, like 80286. With this trick, many programs run correctly, like "EM8087.EXE"
