- the latter is (part of) what my "COLDBOOT" program, posted a while ago, does.
Since it is VERY short, here's a repost.

--------------------

A utility was posted a while ago to make the RESET button do a COLD reset.
I don't like that (since I want to keep the reset-proof RAMdisk) but
occasionally I do need a cold boot.  Since HDB2.3 apparently does not
boot right if I leave the HD on and turn the ST off and on, I wrote the
following little ditty.  It asks for confirmation, then does a cold
reset (that redoes the memory size check, although it keeps the time...).
