2. If the system completes the RAM test, but does not
continue, check the following:
a) Check the assignment of jumpers W57-W59, as
explained in Appendix A.
b) Be sure W12 (located next to the battery) is installed
to allow DOS access to the RAM drive that contains
the configuration variables.
c) Check the placement of the STD DOS EPROM in
socket 5D1 and the 256 Kbytes of RAM in sockets
7D1 and 9D1.
3. If the system previously booted but no longer does,
chances are the 32K RAM drive was destroyed. To clear it,
remove jumper W12 and short the side of W12 nearest to
the extractor to STD bus pins 3 or 4 at the edge connector
of the board. Replace jumper W12 and turn on the STD
system. The RAM drive should now be empty.
