How to Switch into Protected Mode

I need to make modifications to BIOS code which runs at PowerUp or Boot time and I need to access more than the lower 1,048,576 bytes of memory.

Is it possible to switch into Protected Mode 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.
