   On a ROM 01 machine, the RAM5 disk is created/resized only at
poweron or at the end of a selftest. [ROM 3 boxen can resize/recreate
it on a reboot if the appropriate text control panel option is
selected] While the system can easily manage to put a ProDOS
filesystem header on /RAM5 to make it a disk, for some very obscure
reason, Apple never made that disk bootable by default-- forcing you
to initialize it from a disk utilities program, *then* copying boot
files onto it. [If they made it so that you can select RAM5 as a boot
device, then it should be functional after copying boot files, no
extra step of formatting.]

   Sounds like there may be bad RAM in the system. If you've got a
SCSI controller in the system, disable DMA as the ramkeeper does not
tend to work well with it. Also, see about running a ram verifier
program to see if everything's properly functional. See also if the
problem repeats with the ramkeeper pulled and one of the ram cards in
the slot.
