Includes a IO library, has serial support, and all the basic functions such as malloc and free.

Your real mode code actually requires a 32-bit x86 processor. You use 32-bit registers and make reference to GS and FS. All these things require a 386+ processor. It won't run on an 8086/80186/80286 or equivalent processors.

Alright, will redo many functions to be compatible with 80xx.
