ABSTRACT:
The present invention provides a method for accelerating the BIOS running by means of Cache-As-RAM, comprising steps of: a CPU reading a first instruction from a BIOS Flash ROM and beginning to run BIOS programs after a computer is powered on; the CPU turning on a No-Eviction Mode (NEM) of a cache and initializing a Cache-As-RAM (CAR); the CPU copying the BIOS programs to the CAR space from the BIOS Flash ROM and running the BIOS programs completely in the CAR space; at the end of running the BIOS programs in the CAR space, the CPU initializing a system memory; after the system memory is initialized, the CPU again reading the BIOS programs from the Flash ROM; the CPU copying the BIOS program modules that have not been run yet to the system memory from the BIOS Flash ROM; and the CPU running the BIOS programs from the system memory, so as to finish the initialization of the computer platform.
