The invention discloses a data transmission method and electronic equipment. The data transmission method comprises the following steps: receiving a BIOS (Basic Input Output System) exception instruction sent in a startup process; and transmitting pre-stored BIOS data to a main control unit through a data transmission channel between a pre-storage controller and the main control unit according to the BIOS exception instruction. In the scheme, a connection is established between the pre-storage controller and the main control unit, and the pre-stored BIOS data pre-stored in the pre-storage controller are transmitted to the main control unit when the BIOS becomes abnormal and normal startup of the electronic equipment cannot be realized, so that the electronic equipment can be started normally through the data transmitted by the pre-storage controller when the BIOS becomes abnormal, and the problem that the electronic equipment cannot be started up normally for use due to a BIOS exception when a user needs to use the electronic equipment is solved.
Description
technical field [0001] The invention relates to the field of data, in particular to a data transmission method and electronic equipment. Background technique [0002] At present, for all electronic devices, such as: notebook computers, desktop computers, tablet computers, etc., if BIOS (Basic Input Output System, Basic Input Output System) abnormality occurs during the boot process, it is necessary to open the case of the electronic device for repair. When the repairing is completed and the BIOS is normal, the electronic device can be turned on normally. Contents of the invention [0003] In view of this, the present invention provides a data transmission method and electronic equipment to solve the problem in the prior art that when the BIOS is abnormal, it is necessary to open the case for repair. When the BIOS returns to normal, the electronic equipment can be started normally, which is for the user. The specific solutions for the inconvenience caused by normal use and...
