Abstract
The invention provides a method for storing and running large capacity Boot ROM image. It first stores the non-initial code content of Boot ROM image into annex storage medium (such as disk), then it reads non-initial code content and deals with it when running the initial code of Boot ROM image to achieve the support of large capacity Boot ROM image program.
Description
Technical field
The invention relates to the method for a kind of storage and operation Boot rom image, specifically, is the method about a kind of storage and operation high-capacity Boot rom image.
Background technology
People are more and more higher to the requirement of computing machine each side function, impelled the complexity of computer software constantly to increase, this makes software also become more and more huger virtually, this problem is nothing for the storage mediums such as hard disk that calculate with 10G, 100G at present at all, but for some more special application scenarios, as be stored in Boot ROM type program in the PCI expansion ROM (hard disk reduction card, encrypted card, remote activation card etc.), still stubborn problem relatively.With regard to this series products of hard disk reduction card; manufacturer wants to take advantage in intense market competition; means and strategy are a lot; wherein increase product function; with the differentiation of realization with like product, give prominence to the advantage of self, be a kind of very feasible way; the hard disk reduction that adds network function (management, clone) as the hard disk data protection that occurs on the market blocks, and is exactly a kind of relatively more successful representative.Yet owing to be subjected to the restriction of PCI expansion ROM capacity (generally all in 64K) and price, some good ideas implement also difficult.
The object of the present invention is to provide a kind of method that realizes storage simple, that cost is low and operation high-capacity Boot rom image.Knowledge according to the PCI expansion ROM in " PCI local bus standard ", the way of realization of PCI expansion ROM program such as Boot rom image, its structure (as Fig. 1) is mainly divided initialization (Initialization) code and non-setup code part, wherein setup code can be loaded and move in the start-up course of computing machine, and its non-setup code partly can be realized flexibly.According to these characteristics, we just can be with the non-setup code partial content in the Boot rom image, be stored in earlier in the additional storage medium (as hard disk), in setup code in this Boot rom image when operation, as required then, read non-setup code partial content again and handle, to realize support the high-capacity Boot rom image.
Summary of the invention
For above purpose, the invention provides the method for a kind of storage and operation high-capacity Boot rom image, this method comprises:
1.. when writing Boot ROM program, the function of data in the additional storage medium (as hard disk) and the information of Data Position are read and handle in adding in this Boot rom image setup code, generate executable file mirror image (Image) by normal Boot rom image development process, with the setup code part in this Boot rom image, be cured in the storage medium (as FLASH) of PCI expansion ROM, more non-setup code partial content in this Boot rom image write in the additional storage medium (as hard disk);
2.. during the operation of initialize routine in this Boot rom image, read as required and be stored in the content in the additional storage medium (as hard disk) and handle, finish support the high-capacity Boot rom image.
Description of drawings
In claims of present patent application, pointed out theme of the present invention particularly, and clearly it has been proposed patent protection.Yet with reference to following detailed description and accompanying drawing, relevant structure that can better understand the present invention and implementation method with and purpose, feature and advantage.
Fig. 1 is a typical B oot rom image layout;
The Boot rom image layout that Fig. 2 uses for this method.
Specific implementation method
In the following detailed description, having described specific details comprehensively understands the present invention so that provide.Yet the professional and technical personnel will appreciate that the present invention also can implement with other similar details.
Although the invention is not restricted to this,, a kind of that hard disk is as follows as the implementation step of storage and operation high-capacity Boot ROM additional carrier as a specific embodiment of the present invention:
Knowledge according to fdisk, in 63 sectors of the 0th cylinder the 0th magnetic track of hard disk, except that the 1st sector is used for MBR (Main Boot Record), remaining 62 sector all keeps need not, simple and convenient for what handle, we can use these 62 sectors (about 32K), are used for storing the non-setup code partial content of Boot rom image.
1. described set by step, when writing Boot ROM program, in this Boot ROM setup code, add the function of interrupting reading and handling hard disc data by standard BIOS, and be used for storing the non-setup code partial content of Boot rom image, the information of hard disk the 0th cylinder the 0th magnetic track 2-63 sector position, with visit and the processing capacity of reality to non-setup code partial content in this Boot rom image in the hard disk, initialization section content with the Boot rom image that generates is cured in the PCI expansion ROM again, and non-setup code partial content is write in the sector of hard disk.
2. described set by step, when the initialize routine among this Boot ROM is loaded and moves by computing machine, just can read as required and be stored in the content in the hard disk sector and handle, finish support to the high-capacity Boot rom image.Interrupt int 13h by BIOS, directly the partial function code of access hard disk sector is with reference to as follows:
Mov ax, 0202h; 2 expressions are read in the high byte, and 3 expressions are write; Represent sector number in the low byte; 202 just represent to read No. 2 the sector
Mov bx, 1000h; The memory address that is used for the storage read-write data
Mov cx, 1; Sector number
Mov dx, 80h; 80 expression Primary Hard Drives, 81 expressions are from hard disk, and 0 represents floppy disk etc.
Int 13h; Standard BIOS disk funcall
Though herein declarative description certain this feature of the present invention and a kind of implementation method, for the professional and technical personnel, many modifications, replacement, variation and equivalent substitution will appear.Therefore, protection scope of the present invention is as the criterion by the scope of appended claim.
Claims (4)
1. the method for storage and operation high-capacity Boot rom image, this method may further comprise the steps:
