codes. To the contrary, the reference includes the following
teaching.
The special motherboard connector is wired so that
the operator, by setting connections on the field-
installable boot card, can bypass the boot memory on
the motherboard and force the computer to boot from
the memory on the boot card. This permits a
technician, in the field, to temporarily override
the internal nonvolatile memory which holds the
basic system software.... Preferably, the
motherboard boot memory is a flash EPROM, and can be
rewritten, by setting appropriate jumpers on the
boot card, after the computer has booted from the
boot card. Abs., ll. 3-12.
Stewart adds the following teaching.
Once the boot card is inserted into the special
connector, the computer can be rebooted (e.g. by
turning its power off and on). With jumper on the
boot card in its first position, the motherboard
boot memory will be disabled (due to the signal on
line ROMDISABLE), and the boot memory on the boot
card will respond to all attempted accesses to the
motherboard boot ROM. Col. 5, ll. 54-60.
In summary, selection of the boot card memory and the
motherboard boot memory of the reference is based on the
setting of jumpers rather than on whether access is sought to
different codes as claimed.
For the foregoing reasons, we are not persuaded that
Stewart shows the “system ROM,” “flash EPROM,” “ROM,” and
