Abstract
The invention discloses a method and a device for restoring a BIOS (basic input output system) ROM (read only memory) by aid of an EC (electronically controllable) ROM. The method includes preliminarily storing an SEC (security phase) module and a PEI [pre-EFI (extensible firmware interface) initialization] module in the EC ROM; transmitting a BIOS ROM restoring instruction to the EC ROM if a monitored computer cannot be normally started when the computer is started; copying the SEC module and the PEI module stored in the EC ROM into the BIOS ROM after the EC ROM receives the instruction; enabling the BIOS ROM to execute BIOS ROM restoration operation by the aid of a copied SEC module and a copied PEI module after the SEC module and the PEI module are copied into the BIOS ROM by the EC ROM. The SEC module and the PEI module are required for executing the BIOS ROM restoration operation. The method and the device have the advantage that the BIOS ROM can be safely restored by the aid of the method and the device.
Description
Technical field
The present invention relates to BIOS ROM recovery technology, particularly a kind of method of EC ROM recovery BIOS ROM and relevant device of utilizing.
Background technology
Current UEFI(Unified Extensible Firmware Interface, general extension firmware interface) BIOS ROM consists of four parts: SEC(Security Phase, UEFI BIOS unloading phase) module, PEI(Pre-EFI Initialization, the operating subordinate phase of UEFI BIOS) module, DXE(Driver Execution Environment, the operating phase III of UEFI BIOS) module and BDS(Boot Device Selection, the starting outfit choice phase) module.Fig. 1 is the BIOS ROM structural map that prior art provides, and as shown in Figure 1, wherein, the Boot Block of BIOS ROM partly preserves described SEC module and PEI module, and the remainder of BIOS ROM is preserved DXE module and BDS module.Described SEC module for computing machine the earliest unloading phase, this period is very short, code is approximately thousands of row left and right; The described PEI stage is the operating subordinate phase of UEFI BIOS, i.e. pre-Extensible Firmware Interface initial phase, and this stage CPU is operated in 32 states of protected mode, starts and initialization Memory Controller Hub, completes some the most basic hardware chip initial work.The DXE stage is the operating phase III of UEFI BIOS, drives the execution environment stage, and this stage CPU mode of operation transfers 64 long patterns in protected mode to, and BIOS loads all hardware chip drivers, completes the initialization action of all hardware; The BDS stage refers to the starting outfit choice phase, when UEFI BIOS runs to this stage, means according to the pre-set boot sequence of BIOS, starts to start the operating system.
Boot Block is one section of specific region in BIOS, includes the minimum instruction collection for guiding, and normal BIOS updating operation can not be eliminated this segment information.When BIOS ROM data is destroyed, BIOS can start to recovery pattern.The principle of recovery pattern is: in advance SEC module and PEI module are put into the Boot Block part of BIOS ROM, and this part code must guarantee intact errorlessly, not be subject to any destruction.When in BIOS ROM, except Boot Block, part is destroyed, BIOS can order carry out SEC module and the PEI module in Boot Block part, complete the initialization of internal memory, then from External memory equipments such as USB flash disk or CDs, find BIOS DXE module, search after the success of DXE module, (in fact described DXE module and BDS module are placed in the middle of a file can to carry out DXE module above and BDS module, find DXE module, also just found BDS module), finally start under UEFI SHELL environment, use again the burned complete BIOS ROM of BIOS burn recording software, that is to say, by SEC module, PEI module, in the burned BIOS ROM of program of DXE module and BDS module, with this, realize the security recovery of BIOSROM.
As can be seen here, realize above-mentioned Restoration Mechanism, described SEC module and PEI module must be placed on the Boot Block part of BIOS ROM, described Boot Block part can not be subject to any type of destruction, once BootBlock is partly damaged, BIOS again cannot complete SEC module and PEI module, naturally also cannot complete the security recovery of BIOS ROM.
