How to Switch into Protected Mode

[size=4]I need to make modifications to [b]BIOS[/b] code which runs at [u]PowerUp[/u] or [u]Boot[/u] time and I need to access more than the lower 1,048,576 bytes of memory.

Is it possible to switch into [b]Protected Mode[/b] at this time in order to access more memory? If so, how? What is the instruction sequence?

Alternatively, can anyone suggest a different approach?


Thanks,
Bob.
