Actually, rebooting the CoCo doesn't have to lose the ramdisk.  I use KD's
"Rammer" and have my startup set so that the Ram Disk is QUARANTEED to get
the same ram (that no other statup program uses) each boot.  Then before I
call "Format" I call a little program I wrote to read LSN0 from the ram disk
and compare it to a copy I kept of the hard drive.  If they match, and a
"dir -e" executes on '/r0' then I assume no problems and leave the ram disk
intact.  Otherwise I reformat it.
