MS-DOS 4.00

This is MS-DOS 4.00 taken from the Microsoft repo: https://github.com/microsoft/MS-DOS

This is based off the modifications made by neozeed (of Virtually Fun) and other fellas. This is mainly a fork to experiment with the source code, maybe even translating it into Filipino (for the fun of it).

This is based off huge hard work from Microsoft and IBM.

Yes, it does compile. Yes it can DOES boot from Hard Disk. Yes the CALL 5 debug thing has been patched. Enjoy!
