loading code at a given memory position

[Rolando J. Zappacosta]

Hi all,

I wondering if it would be possible to use grub to set the a FAT
partition as the active one, load a file from it into a specific
memory location and finally launch part of the loaded from a given
entry point.

The code will then access the FAT filesystem to load some other files it needs.

Is this possible? Any hints on how?

TIA,
Rolando
