Description of the Invention: [Technical Field] The present invention is a method for reading a memory code, especially if the computer device is automatically turned on to a storage device, read and executed therein. The optional read-only question (Option _, the following dragon __ code) required to drive the various adapter cards on the computer device is used to smoothly start the connection with each needle tree. [Prior Art] According to the 'computer device (such as: desktop computer, notebook computer and 祠, 斋, etc.) installed on the choice of read-only memory (〇pti〇n job, hereinafter referred to as _M) '- (four) refers to the county This input/output system (such as I_/Gutput System, the abbreviation of BI_#_M (firmware) resident program, for example, _ light field money _ needle (on the gamma or daughter card) as an example, the adapter card The stored 〇pR〇M system=peripheral device is connected to the computer device through the adapter card to control the booting of the peripheral device (5〇), so that the computer device is obtained. Through the question (int(10)gate) _M, it is decided that the peripheral devices connected to them are Booted 〇In order to connect various commercially available computer devices with a large number of peripheral devices, the manufacturer will install various adapter cards on the computer devices before they leave the factory. Traditionally, 〇PR 〇M system is resident on the riser card, so each flash 2 must have a flash memory for storing 〇P_, which is the number of W 的 闪 § 己 体 自然 天然 天然 天然 天然 天然 天然σ. In order to save the cost of hardware 200805083, the design and manufacturer of the computer device chose to store the 〇pR〇M and BI〇s together on the flash memory (system flash) provided on the system board (system b〇arci). In the ROM), it is resident on the computer device, so that the 〇pR〇M is executed by the BIOS during the initialization of the computer device. In principle, the storage space of the OpROM (0pR〇M Shad〇w RAM) is Limited to 128 KB, this storage space is shared by all 〇pR〇M, and the restrictions are obviously strict. Therefore, each 转接pR〇M of the riser card needs to be used to get rid of some of the initialization process. Initialization code, leaving only a small space The amount of the runtime code 'to reduce its own space, otherwise, in the case of limited storage space, the number of adapter cards that can be installed on the computer device and its expansion will naturally be limited. However, because the OpROM program developer (devei〇per) is in the process of doing the 5 and taking into account the development of the QpROM function, it is often necessary to debug the OpROM, and update (upciate) 〇pR〇j When you need to use the BI〇s program image or source code for rebuilding, this will not only cause great inconvenience to the programmer, but also make it easy for the programmer to design the BIOS. The program content or source code is leaked externally (if the OpROM program is an outsourced design developer). In addition, since the 〇pR〇M&BIOS is normally stored in the flash memory on the motherboard of the computer device, the contents of the OpROM or Bios program are frequently updated, which may cause the flash memory to be damaged. In addition, since the space for storing the flash memory of the 〇pR〇M and the BIOS program is generally small, it is impossible to put the Big 1 OpROM and the BIOS into the same flash memory. 8 200805083 [Summary of the Invention] With the above problems, the inventor has finally worked hard to study and experiment, and finally developed a method for reading and selecting a read-only memory code on a self-storage device of the present invention, and the computer device and The riser card on the switch does not need to be installed to store the memory of the OpROM, so as to reduce the hardware cost, and achieve an effective simplified update and debug procedure, increase the expansion and charge capacity of the computer device, and ensure that the BIOS program does not leak. The function. For the purpose of the present invention, the method is applied to a computer device equipped with at least one storage device, including a dedicated partition in the storage device for storing and driving various types of devices on the computer device.

In this case, in the process of loading all 〇pR〇M code into the memory, all OpROM code stored in the dedicated partition of the hard disk is preferred; and (1〇6) temple j. When the subsequent BI0S standard procedure is executed, the completed BBS enables the peripheral devices connected to each of the riser cards to be successfully started. 200805083 According to the above description, the 'Benfa County (10)_ storage surface division area, and after the electric contact device is activated, the 〇_ is loaded into the cryptographic body of the _ device. The method of connecting and closing has the following advantages. (1) When the OpROM code is updated, the dedicated partition in the hard disk is updated, so that the security of the flash memory is ensured; (2) BIOS For programmers, it provides great convenience. ^In the case of more difficult code (10), there is no need to rebuild the program content of Na, just by replacing 〇pR〇M in the original dedicated partition. The program developer has any new 0pR0M, and the new OpROM can be replaced with the new 〇pROM by using the present invention. For 〇pR〇M developers, it also provides a very convenient tool, so that it can be used at any time, without rebuilding the BIOS program content, which can effectively avoid the initial code being seen by (10) the sender. It has the function of ensuring that the contents of the BIOS program are not leaked out; (3) The new OpROM is stored in a large storage device (such as a hard disk), so that there is no space limitation, the storage is large. The OpROM code 'When the BIOS flash memory has insufficient storage space', the remaining OpROM code can be stored in the large storage device to effectively solve the BI0S flash memory storage space to store all the 〇pR〇M code. The problem is not only that, but the invention can also choose to store all 〇pR〇M code (except VGA OpROM code) in a large storage device, and only need to store BI in a read-only memory with a small storage space. s program content, so 'will effectively reduce the cost of BIOS flash memory; (4) because each computer device is generally equipped with at least one hard 16 200805083 disk 'and drive the hard disk (such as · · SATA hard drive) The program is generally stored in the BIOS flash memory set on the motherboard, or the hard disk (such as: SCSI hard disk) 〇pR〇M code is generally stored on the riser card. Flash memory, so the use of hard disk as a storage device does not require additional cost, and the total space occupied by all OpROM code is insignificant relative to the hard disk space, so for all OpROM code, there is no The problem of insufficient space;

Therefore, there is no need to design or reserve the memory space for the 0pRGM& code on each riser card. Significantly reduce the cost of memory construction; (8) If you want to support (support) a new adapter card, but cut (10) flash memory is empty, just save its GpR_ code to the hard disk, effectively increase The expansion capabilities of computer devices.
