Abstract

본 발명은 키보드의 잠금기능을 프로그램으로 실현하는 퍼스털 컴퓨터의 키보드 잠금방법에 관한 것으로, 퍼스널 컴퓨터의 키보드 잠금을 위한 패스워드와 핫키가 미리 설정된 상태에서 동작이 시작(101)되면 BIOS인터럽트(102)를 걸어 현재의 핫키를 입력(103)하는 제1단계와, 상기 핫키가 눌려졌으면(104) 상기 설정시 사용자가 정한 키정보를 CMOS레지스터에 기록(106)하는 제2단계와, 상기 기록을 다시 읽어서 해당키가 핫키일때 비프음을 낸 다음 프로세서(8042)에 명령하여 패스워드 바이트를 전송(108)하는 제3단계와, 사용자가 설정한 문자의 수에 따라 루푸(110)를 돌아 CMOS레지스터에 문자데이타를 순차적으로 저장하는 제4단계와, 상기 문자데이타를 모두 저장한 후 프로세서에게 보안문자 전송이 끝났음을 알려주고 보안 인에이블을 명령하는 제5단계를 순차적으로 실행하여 제어프로그램에 의해 키보드 잠금을 실행하도록 한 것이다.The present invention relates to a method of locking a keyboard of a personal computer that realizes a keyboard locking function as a program. When an operation is started 101 in a state where a password and a hot key for locking the keyboard of a personal computer are set in advance, the BIOS interrupt 102 First step of inputting the current hotkey (103), if the hotkey is pressed (104), and writing the key information determined by the user at the time of setting (106) to the CMOS register; and rewriting the recording. A third step of reading and making a beep when the corresponding key is a hot key, then instructing the processor 8042 to transmit a password byte 108, and then returning the loop 500 to the CMOS register according to the number of characters set by the user. A fourth step of sequentially storing data, and a fifth step of notifying the processor that the CAPTCHA transmission is completed and instructing the security enable after storing all the character data. The next step is to execute the keyboard lock by the control program.
