Switching from PMode to Real Mode

[Matt]

Could somebody give me the ASM code to switch from protected mode to real mode? All the stuff I could find in the internet about doing that makes no sense to me :-/
[glow=green,2,300]Thanks [/glow]

[crazybuddha]

mov eax,cr0
or al,1
mov cr0,eax

[matt]

mov eax,cr0
or al,1
mov cr0,eax

[frank]

that is switching back .. (are you sure, you switched from realmode to pmode before?)

mov eax,cr0
or al,0
mov cr0,eax

and ofcourse do some otherstuff (don't know what, I don't have more than 1 mb of gig for nothing ) -- search on the internet
