发明名称 Remote initiation of BIOS console redirection
摘要 A server management tool which allows remote initialization of BIOS console redirection on a computer system (e.g., server computer). Server computer is coupled to a remote console via an asynchronous connection. Console redirection is initiated by generating a serial break on the asynchronous connection via the remote console. The server computer detects the serial break by a break detect circuit. The break detect circuit then generates a signal which places the CPU of the server computer into system management mode (SMM). After server computer CPU is in SMM, a password and console redirection request are passed to the server computer from the remote console via the asynchronous connection. After the password sent by the remote console has been authenticated by an SMI handler routine within the server computer, the SMM of the CPU processes the redirection request by calling the basic input output system (BIOS) and the SMI handler routine. The serial break within the server computer is cleared after processing the console redirection request.
