Appeal No. 97-4062 Page 3
Application No. 08/590,049
Claim 1, which is representative for our purposes,
follows:
1. In a computer system including a central
processing unit ("CPU") capable of issuing a signal
to a memory to retrieve a requested instruction from
said memory when said CPU is booted, a circuit,
transparent to said CPU, capable of localizing
faults within said computer system, comprising:
an interception and substitution circuit,
coupled to said CPU, capable of intercepting said
signal and providing an alternative instruction to
said CPU in lieu of said requested instruction, said
alternative instruction directing said CPU to
perform a diagnostic check of said computer system,
said CPU providing an indication of proper
functioning of said computer system, said CPU
requiring no hardware modifications to operate in
conjunction with said interception and substitution
circuit.
The reference relied on in rejecting the claims follows:
Warchol 5,327,435 July 5,
1994.
Claims 1-33 stand rejected under 35 U.S.C. § 103 as obvious
over Warchol. Rather than repeat the arguments of the
appellants or examiner in toto, we refer the reader to the
brief and the answer for the respective details thereof.
