If there is a chemical formula in this case, please disclose the chemical formula that best shows the characteristics of the invention: • Nine, invention description: [Technical field of the invention] - The present invention provides a memory detection method, in particular, a host, a board The firmware is used to detect whether the memory is mixed, the memory capacity is the same, and the error message is reported. [Prior Art] ^ The firmware of the motherboard is not provided with the judgment memory intermixing (the label is different), the capacity is different, and the memory is not inserted, and the judgment is made and the user is given an error warning. DIMMO has no plug-in memory, and when other DIMMs are plugged in, the firmware of the conventional technology still determines that there is no memory, which causes the booting to be impossible, and the user does not have the error of the mixed insertion or capacity of the memory. Receiving any error message and performing the booting action will not cause the system to be damaged, but it may also result in failure to boot or the memory cannot be fully operated, which indirectly causes loss of money and efficiency of the user. 1335598 To meet the above-mentioned need to improve the functionality of the conventional firmware. The present inventors have been engaged in research and many practical experiences based on many years of research and design, and have explored a memory detection method as the implementation method and basis of the foregoing period. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a method for detecting a memory, in particular, a firmware of a motherboard for detecting whether a memory is mixed, whether the memory capacity is the same, and an error message is reported. method. The edge is that, for the above purpose, the memory detecting method according to the present invention is applicable to a firmware of a motherboard, and the method includes at least: (a) detecting a plurality of memory slots (DI匪Slot) , to determine whether • f has at least one memory, and if so, perform step (d), if not, perform step (b); (b) load an initialization program to a central processing unit (CPU) (c) driving a display device through the initialization program; and φ (d) displaying a memory detection message through the display device. The memory detection message is a memory status message or an error message with no insertion memory. According to the memory detecting method of the present invention, the firmware automatically determines the state of the memory, checks whether the mixed insertion, the capacity is the same, or the state without the inserted memory, and records an error message for use. For reference, let the user know if the system memory is fully operational. In one aspect, the invention can reduce the possibility of users inserting different capacity memories by mistake, and indirectly exerts the full performance of the memory 5 Γ 585598, on the other hand, it can provide users with the purchase to avoid accidental insertion or no insertion of memory.
