If you wish to have the system boot from the Flash/ROM disk,
simply set both J27(9-10, 11-12) closed to select the 1st FDD. Copy
your application files to the disk along with the standard system
files required to boot (command.com, io.sys, autoexec.bat, etc). The
next time you start the system, it will boot from the solid state disk.
After you've set all the jumpers on the PCM-4862, insert the
appropriate memory devices into the card's sockets. Remember that
you will need to program EPROMs before you insert them.
1. Make sure that the pins of the memory chips are perpendicular
to the case and both rows are parallel to each other. Often the
chips come with the pins spread out slightly. Place the chip on a
table top and carefully bend each line of pins together until
they point directly down.
2. Insert each chip. Align the chips so their pins are perpendicular
to the connector and the semicircular notch on the end of the
chip matches the notch on the end of the socket. There will
probably be a gap between the chip body and the socket when
it is fully seated – Do not push too hard!.
