Claim:
1. A method for increasing speed of a boot sequence in a computing device: beginning a firmware-executed boot sequence for the computing device; identifying a disk read request for code or data during the boot sequence; determining that the disk read request is requesting a read of a read-only disk; determining whether a corresponding cache exists in a system Read Only Memory (ROM) for the computing device, the corresponding cache being a cache identified as corresponding to the read-only disk; determining, when the corresponding cache has been determined to exist, whether the requested code or data is in the corresponding cache; and retrieving, with the firmware, when the requested code or data has been determined to be in the corresponding cache, the requested code or data from the corresponding cache instead of from the read-only disk, the retrieved code or data used in executing the boot sequence.
