The invention provides a single-epoch fixing method for enhancing PPP-RTK ambiguity of regional foundation. The single-epoch fixing method comprises the following steps of: improving the ambiguity convergence time of a PPP-RTK method by carrying out optimizing ordering on the fixing feasibility of single-difference ambiguity between alternative satellites, respectively modeling for an observed value residual error of a CA / P1 pseudo-range and observed value residual errors of L1 and L2 phase positions by adopting a single-reference station processing mode based on a PPP-RTK technique, and realizing the single-epoch fixing of combined ambiguity of an ionization-free layer through step-by-step solving of the ambiguity in consideration of a linear constraint relationship between the high precision of a pseudo-range observed value, long wavelength of a wide-lane observed value, wide-lane ambiguity and L1 ambiguity after a user refines the models, thus the determination time of the PPP ambiguity is minimized, and the working efficiency of precisely locating the user is improved to the maximum degree.

The invention provides a multi-BIOS mapping parallel initialization method. The method is different from a traditional single-BIOS serial initialization method. The method designs a traditional computer system to an initialization computer system with that multi-BIOS is directly connected with a processor for parallelism through a method that a single-BIOS is carried on a multi-level bridge controller for initializing system in a parallel mode on the basis of creatively altering traditional computer system structure. The multi-BIOS mapping parallel initialization method realizes direct connection of the multi-BIOS with the processor, fastens the speed of system initialization, and enhances running efficiency of the system and high availability of the system.

The invention relates to a method and device for initializing RAID. The method comprises the steps that a CPU receives an RAID establishing command sent by a client side; the CPU determines a plurality of target disks based on identification information of the target disks in the establishing command and constructs corresponding initializing commands for the target disks respectively based on hardware information of the target disks; the CPU sends the initializing commands to an initializing module based on an FPGA; the initializing module based on the FPGA receives the initializing commands issued by the CPU and constructs corresponding initial frames based on the initializing commands; the initializing module based on the FPGA sends the initial frames to the target disks respectively, so that the target disks are initialized based on the initial frames. According to the method and device, the initializing module based on the FPGA can directly interact with the disks, therefore, IO operation in most operation systems can be reduced, and the loads of the operation systems can be relieved.
