  • Patent number: 5943218
    Abstract: The present invention relates to a card type CPU fixing structure, characterized in that when said card type CPU (CELERON) is inserted in the main board of Pentium II framework, there is no need to change the support seat. All the user has to do is to fasten the fixing cover on the support seat, the channel on the inside of the fixing cover will press the card type CPU (CELERON) in position, so the card type CPU (CELERON) will not wobble. With the invention, the interchange between a cartridge type Pentium II CPU and a card type CPU (CELERON) can be made readily without having to replace the support seat of the main board. With the invention, the manufacturers of main boards will not have to produce additional compatible components after the card type CPU (CELERON) is put on the market, while the user will be able to replace the CPU easily and readily.
