Appeal No. 2001-0164 Application No. 08/885,379 during a boot-up phase and when a possible source of the operating system is detected, having the CPU (80) check to determine whether such detected source is operational and has a valid boot format (402). See Appellants' specification on page 38, lines 1-11 and 25-32 and associated Figure 16. If the detected source is operational and has a valid boot format (403), the method includes the step of having the CPU boot the detected operating system into the main memory (404). See Appellants' specification on page 39, lines 2-6 and associated Figure 16. If the detected source is either non-operational or does not have a valid boot format, the method includes the step of having the CPU check another one of the possible operating system sources (405). See Appellants' specification on page 39, lines 6-10 and associated Figure 16. If all sources are checked and none are both operational and have a valid boot format, the method includes the step of having the CPU repeat the aforementioned sequential search of the possible operating system sources. See Appellants' specification on page 38, lines 19-22, page 39, lines 31-33 and associated Figure 16. The only independent claim 1 present in the application is reproduced as follows: A method for booting operating system software into a main memory of a CPU, comprising the steps of: 2Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
