Appeal No. 1999-2216
Application 08/805,399
Shinjo, the main reference, is directed to a method and
apparatus for quickly booting a computer system after an
initial boot process. The normal mode of Shinjo has a
"quick start mode" in which a high speed boot can be
executed using the backup data, and a "saving mode" in which
the main memory data stored in the main memory 12 is saved
in the backup memory 13 as backup data immediately after a
normal boot (col. 2, lines 57-62). A backup flag 15 is set
to indicate the quick start mode and is reset to indicate
the saving mode (col. 2, lines 62-67). When Shinjo is
started in the normal mode and the backup flag is reset, a
saving mode is selected (the "NO" path from step S2 in
Fig. 2). A conventional boot process is executed comprising
executing the operating system (OS) initialization process
(step S4) and the application initialization process
(step S5) by the initialization program (Fig. 2, col. 3,
lines 16-23); main memory data is copied into backup
memory 13 and the backup flag 15 is set (step S8); and then
a system reboot is executed. Since the backup flag has been
set, the boot process is started in the quick start mode
through steps S2 and S3 (to the "YES" path in FIG. 2) after
