Hi
I have a boot sector program that I want to load another program from the disk.

Since free space on the 512KB Boot sector is limited, I want to go straight to the start of the data part of the disk (ignoring the FAT).

I want to load this file from disk into memory and then execute it.

Please note, this is in Real Mode.

1. How do I set aside some RAM and load it in (I know it's using Int13).

2. I'm not sure how to execute it, I know I take the CPU to it with a JMP Instruction, but I need some helpful advice.
