I`ve managed to run the initial version of the ROM Monitor program and placed it in FLASH memory. Here is a list of available commands:

dump: Memory dump from a given address
edit: Memory editor.
fill: Filling the memory with fixed content.
copy: Copying one part of the memory to a different location
cls:  Clearing the screen.
input: reading a byte from I/O port
output: sending out a byte to I/O port
jump: Jump to given address.
load: loading data/code to RAM memory trough bootloader board connected to input port on the motherboard.
