The elastic pin is penetratingly provided and fixed to the wall, front and rear ends of the elastic pin are respectively located in an inner portion and an outer portion of the wall. The cover is provided with one plate and one socket, the plate of the cover can be embedded into the fixed base, so as to enable the front end of the elastic pin to be inserted into the socket of the cover, and enable the cover and the base to be mutually fixed, thereby achieving a covered portable stove burner structure for facilitating convenience in grasping and safety in carrying without accidental separation.

Abstract: A method for booting a computer device can be applied to a basic input/output system (BIOS). Whether backup data of a master boot record (MBR) is stored in the BIOS is first determined. When the backup data of the MBR is not stored in the BIOS, actual data of the MBR is backed up to the BIOS; when the backup data of the MBR is stored in the BIOS, the actual data of the MBR is compared with the backup data of the MBR. Then the backup data is restored to MBR when the actual data is different from the backup data.
