Abstract
Disclosed are a circuit and method for remote diagnosis of personal computers. The method comprises the steps of (1) confirming an existence and a proper operation of a modem coupled to the personal computer, the step of confirming performed in a central processing unit ("CPU") of the personal computer and in a diagnostic environment independent of a normal operating system of the personal computer, (2) receiving an indication of a selection of diagnostic routines to be performed from a remote location via the modem and (3) performing selected ones of the diagnostic routines as a function of the selection. The present invention allows an experienced technician located remotely from the computer to interact as though seated in front of it, to thereby allow remote diagnosis of even critical faults that prevent the computer from booting.
