Protected Mode Bootable Debugger

"ProDebug"

"ProDebug" is a Protected mode bootable debugger , it can boot off a floppy and can be used to debug protected mode programs in the 386 class of intel processors. It can also be used as an educational tool to teach about the protected mode by writing small programs and tracing through them,watching what happens to the processor registers and various tables like gdt ,ldt etc.
It is designed as a small kernel,provides support to handle the keyboard,screen (with scrolling capabilities) and the floppy drive.It also provides a few system calls that the user programs can use to access the above periphrals. It was coded in C and Asm like most kernels.
