Appeal No. 96-2693
Application No. 08/018,972
CPU (as determined by PKZIP) is not the only significant
hardware attribute of a computer system. As taught by MWRK,
plural hardware attributes should be determined before
deciding the operating mode of the MWRK software. On page 63,
MWRK automatically runs on a standard mode or enhanced mode
after determining whether the system has an 80286 CPU and 256K
of free conventional memory and 192K of free extended memory
or an 80386 CPU and 2 megabytes of memory
(256K of free conventional memory and 1024K extended memory).
Thus, just as plural hardware attributes are determined before
selecting the MWRK mode of operation, the Examiner reasons
that determining plural hardware attributes would further
enhance PKZIP in optimizing itself. PKZIP itself teaches the
use of detecting plural attributes as noted on page 1, i.e.
"80386 CPU detected, XMS version 2.00 detected, Novell Netware
version 3.11 detected, DPMI version 0.90 detected".
With regard to Appellants' claim 4 limitation that "at
least one of the plurality of hardware attributes is
associated with cache memory resources", the Examiner notes
