Log message:
Avoid accessing .data or .bss from real mode, since they may not be within
the current segment. Load and store the necessary BIOS registers from
protected mode, preserving the register values across the real mode and
protected mode switches by directly patching instructions. This allows for
boot(8) to be larger than 64KB.
