“Chan did not explicitly give details about the sector of the
flash ROM includes [including] at least two different
programs, one of which is to erased and one of which is not to
be disturbed.” We agree. Chan uses an INTEL flash ROM
(column 7, lines 35 through 45) that is not concerned with
storing a plurality of different types of data (e.g., boot
code, EISA configuration code, Ediags instruction code, and
main BIOS data) in a single sector (e.g., sector 7 in an AMD
flash ROM used by appellant in Figure 3). Thus, we agree with
appellant’s argument (Brief, pages 4 and 5) that:
Chan teaches the one-way transfer of data from the
UV-PROM to the Flash EPROM, and has no teaching or
discussion about transferring a portion of a sector
of Flash EPROM to RAM and then back to the Flash
EPROM after the Flash EPROM has been erased, as in
the present invention. In fact, Chan teaches away
from this proposition because the Flash EPROM is
only written to when there is a data inconsistency
with the UV-PROM, thus rendering the data in the
Flash EPROM obsolete. (Emphasis added).
We also agree with appellant’s arguments (Brief, page 5) that
“Chan is completely devoid of any teaching or suggestion of,
among other features, installing a new Interrupt 15 routine
and executing the new Interrupt 15 routine whenever an
