Is there a way to force a cold boot on the ST?

The reason I ask, some games on pp's hdd game collection seem to setup the mmu so that TOS thinks there's only a meg of RAM and this persists across a reset. I wouldn't mind (that much) flipping the power switch, but that doesn't actually seem to get me a cold boot on my ST, presumably because the caps take a long time to empty or the ACSI hdd drive I have plugged in with external power ends up keeping some part of the ST warm? Completely unplugging everything and plugging it back in gets me a cold boot, but that's pretty cumbersome.

Perhaps my real question is, is it possible to reset things so that any mmu tinkering that has happened gets reset?

If you're running TOS 1.04 or later then Ctrl-Alt-Shift-Del should do it.

Thanks, this does the job! Only thing worth noting is that it has to be right-shift, left-shift funnily makes the combination not work at all...
