Application software loading method for computer data processing system

摘要

The method involves loading an application software into a programmable read-only memory, preferably an EEPROM, of a data processor, whereby the read-only memory comprises a boot sector with a boot program which includes functions for deleting and programming the read-only memory as well as at least one copy function. At least a section of the boot software including the functions for deleting and programming the read-only memory is copied by the copy function onto identical memory addresses of a read/write memory, and the application software is loaded by the boot software located in the read/write memory into the programmable read-only memory. The switching between the programmable read-only memory and the addressable read/write memory is performed through generating a programmable Chip-Select signal.
