Description

How to switch the boot mode automatically

technical field

The invention relates to a computer startup program, in particular to a method for automatically switching startup modes.

Background technique

Please refer to Figure 1. Dual In-line Memory Modules (DIMM for short) 1 and Single In-line Memory Modules (SIMM for short) contain multiple memory chips (Memory Chip) ) small circuit board. The configuration format of the dual in-line memory module 1 has 72, 144 and 168 terminals (pins). RAM for short) chip can be said to be formed by merging two single-in-line memory models. Like a single-in-line memory module, it can also be manufactured on one or both sides. If the dual in-line memory modules 1 are installed on a motherboard, it is not necessary to add the dual in-line memory modules 1 in pairs, and they can be mixed and paired. For example, you can add a 64 Mega Byte (Mega Byte, MB for short) dual in-line memory module 1 to the slot 2 next to the 32MB dual in-line memory module 1 . The difference between the dual in-line memory module 1 and the single in-line memory module is that the terminals on both sides of the circuit board of the former have their own independent circuits, while the circuits of the terminals on both sides of the latter are connected together, that is, the dual in-line memory module The terminals on both sides of 1 have their own special definitions, so that they can provide a wider access path, so that their data transmission speed is faster than that of a single in-line memory module.

For the dual in-line memory module 1 with 168 terminals, the access path of its memory chip is 64 bits (bit), and if the bus (BUS) of the central processing unit (Central Processing Unit, referred to as: CPU) is the same It is a 64-bit access path, and only one complete access (Access) operation is required for the memory, so only one dual in-line memory module 1 is required on a main board (Main Board, or Mother Board). And the dual in-line memory module 1 also includes an Erasable Programmable Read-Only Memory (EPROM for short) for the Basic Input Output System (BIOS) to store various parameters , and according to the parameters, set a chipset (Chipset) to achieve the best state. On high-end personal computers or workstations, the dual in-line memory module 1 used is mainly based on 200 pins, providing a 72-bit access bus, of which 64 bits are the data itself, and the remaining 8 bits It is used as Error Checking and Correction Code (ECC for short).

The basic input and output system is the most basic in the booting of the computer. When the motherboard leaves the factory, various basic parameters or programs for booting are burned in the Flash ROM, which means that its most basic function is to store the basic information of the computer. At the same time, the user can also set the boot mode and the relevant parameters of each hardware in the computer through the basic input and output system. Generally, when the computer is turned on, the basic input and output system will perform a power on self test (Power On Self Test) to determine the basic configuration of each hardware of the computer. For example, when a general computer is turned on, the basic input and output system will perform three access tests on the memory (if it is set to enabled, it will only be done once, which can speed up the boot time), and then store various parameters in it. In the erasable programmable read-only memory of the dual in-line memory module 1 , subsequent startup software (such as operating system) can obtain the configuration setting values of each hardware of the computer.

As far as most computers are concerned, most of their motherboards use the Intel 815E chipset, which only supports 3 slots 2 of dual in-line memory modules 1, and a total of 6 memory address lines (CSA#0~CSA#5) , or called memory bank (banks), but in order to provide a more flexible way of use, the computer uses the third slot 2 and the fourth slot 2 of its motherboard to share the memory address signal CSA#4 and CSA #5. Because of this design, when the third slot 2 and the fourth slot 2 must be used at the same time, only one bank of Synchronous Dynamic Random Access Memory (Synchronous Dynamic Random Access Memory, referred to as: SDRAM), usually a single-sided SDRAM module, otherwise the BIOS will only detect the memory capacity on the third slot 2, but cannot detect the memory capacity on the fourth slot 2.

On the other hand, if only one dual-in-line memory module 1 is used on the computer, the dual-in-line memory module 1 must be installed in the first, second or third slot 2, otherwise the various parameters stored in the BIOS will be lost. When the computer is turned on, it cannot be loaded into the dual in-line memory module 1 in the slot 3, so that the computer cannot successfully complete the booting process. In addition, the configuration of the first and second slots 2 is set as a pair, if the first and second slots 2 are equipped with dual in-line memory modules 1, the BIOS will be in the Between the first and second slots 2, the dual in-line memory module 1 is interleaved, and various parameters stored in the basic I/O system are stored in the dual in-line memory module 1 respectively.

However, before the BIOS loads the various parameters stored in it into the dual in-line memory module 1, it will perform multiple access tests on the dual in-line memory module 1, as long as it detects once After the dual in-line memory module 1 installed in the first or second slot 2 has a damaged state or an access error, the BIOS will no longer load its stored parameters into the In the dual in-line memory module 1, the computer cannot successfully complete the boot process, which will cause confusion and inconvenience in use.
