I patched Bochs to control the A20 line via the bochsrc file

[OSCASSEMBLY]

I patched Bochs so we can control the state of the A20 line via the bochsrc file in a BIOS-independent way.
I made that for me and it turned out to be really helpful.
So you may find it useful too.

Here is my fork on Github:

Wouldn't it make more sense to patch the Bochs BIOS rather than Bochs itself?

I said I made that because I wanted a BIOS-independent way of controlling the A20 line.
What if someone wants to use a BIOS that he doesn't have access to it's source code, and it enables the A20 line?

Does Bochs support any closed-source BIOSes?

This has been discussed before: https://github.com/bochs-emu/Bochs/pull/911

When I get a chance, I may be able to patch https://github.com/fysnet/i440fx and the make_cmos_image.cc file to do just that. I can look at the standard BIOS included with Bochs, as well.

The idea is a good idea, though I agree, it should be in the BIOS, not in the Bochs tree.

Guys it won't hurt
I just thought that it is a good idea to share it

Besides, yes, Bochs support a lot of BIOSes. Some of them are closed source perhaps.

Yeah I am the author of that PR
