It's not a bug...I just fixed my jump logic. But, just to prove I'm not a liar
like MTS(who left for topica. YES!!!), I'm showing you my latest code. Right
now, it supports a limited instruction set(I'll be working on that) and comes
with a tiny demo boot sector.
In this release:
Loads a ROM image from a crappy old computer(a Compaq Deskpro 4/33i, but it
doesn't do anything with it yet)
Loads a disk image and places the boot sector in memory
Limited BIOS disk access support(it would help if I got more info about BIOS's
completely overly complex coordinate system)
Some video BIOS support
Includes a screenshot :)
Note that
All BIOS is emulated
No hardware is emulated yet(it'd help if someone directed me to a site about
VGA adapters and how to use them, or at least EGA). That's why I emulate BIOS.
It's completely portable! But for full functionality, use it in DOS.
Enjoy!

*snippage has occured*
Well i must say im rather impressed in this little VM. not that i've used many
VM's or anything but this little "xVM" can do some cool stuff. It definately has
potential for a real VM if you keep at it.
I want to look at it a little more in-depth so perhaps later i will be able to
give more useful feedback (like bugs, etc).

I already found a couple of bugs:
* ROM is loaded even when you restart the VM(which is painfully slow on
my P133 on rh6.1)
* A little error in debugging
