Abstract

The invention discloses a computer boot device, which comprises a password keyboard, a singlechip, a storage chip and a switching circuit, wherein the password keyboard, the storage chip and the switching circuit are all connected with the singlechip; the switching circuit is also connected with the boot signal end of a main board of a computer; the singlechip receives a password input by a user through the password keyboard and compares the password input by the user with the password stored in the storage chip; and if the password input by the user is as same as the password stored in the storage chip, the conduction of the switching circuit is controlled so that the boot signal end of the main board of the computer controls the boot of the computer. The computer boot device is convenient for the user to boot by using the password.

Description

technical field [0001] The invention relates to a computer startup device, in particular to a device for realizing computer startup by inputting a password. Background technique [0002] At present, most of the computer systems enter the BIOS (Basic Input / Output System) or the password setting interface of the operating system to set the power-on password after the computer is started. Enter the correct password, the computer can enter the operating system. The above-mentioned power-on password setting methods are all set after the computer is started and enter a specific interface, which is inconvenient to operate. Contents of the invention [0003] In view of the above, it is necessary to provide a computer boot device to facilitate the user to set the computer boot password. [0004] A kind of computer start-up device, comprises a cipher keypad that comprises several keys, a single-chip microcomputer, a memory chip and a switch circuit, and described cipher keypad, me...
