There are cases when a system needs to be patched before the OS is booted. For example the Hardware may need to be configured to support the OS, or some additional information may need to be configured into CMOS for the BIOS to correctly function. Also there may be a requirement to repair a OS boot virus with out booting the OS and having the Virus activate. Today these are accomplished by rebooting to DOS, or some other pre OS; however these present issues with the customer, and could not fix all problems. The method implements a means to supply a patch that the Master boot record can apply to the system before any OS is started.
