Post speedup in oprom systems with intervention support
Techniques related to personal computers and devices sharing similar architectures are disclosed. Particularly shown is a system and method for enabling improved computer initialization speed achieved by methods including causing apparently premature timeouts when fruitlessly waiting for human intervention.
1 . A method for initializing a computer comprising steps of:
detecting a presence of an option-ROM (Read-Only Memory) having a plurality of instructions encoded in the option-ROM;
passing control to the instructions; and
responsive to a request implemented by a portion of the instructions, causing a premature timeout condition or a premature incipient timeout condition.
2 . The method of claim 1 wherein
the request is a keyboard status inquiry.
3 . The method of claim 2 wherein
the request is an interrupt based keyboard status inquiry.
4 . The method of claim 1 wherein
the request is an interrupt.
5 . The method of claim 1 wherein
the request is an interrupt type 16h, AH=01h based check keyboard status request.
6 . The method of claim 1 wherein
the request is a debug register trap to a timing resource.
7 . The method of claim 1 wherein
the causing is an incrementing or decrementing of a BIOS (Basic Input-Output System) timer variable.
8 . The method of claim 1 wherein
the causing is an advancing of an ACPI (Advanced Configuration and Power Interface specification) variable.
9 . A method for initializing a computer comprising steps of:
recording a first status to indicate a commencement of an execution of a plurality of instructions encoded in an option-ROM;
commencing the execution;
responsive to detecting the first status,
causing a premature timeout condition or a premature incipient timeout condition; and
responsive to detecting an execution of an exit instruction comprised within the plurality of instructions encoded in the option-ROM,
changing the first status into a second status to indicate an end to the execution of the plurality of instructions encoded in the option-ROM.
10 . A computer-readable medium having computer instructions encoded thereon, the instructions when executed by at least one computer cause said at least one computer to become initialized by steps comprising the acts of:
detecting a presence of an option-ROM (Read-Only Memory) having a plurality of instructions encoded in the option-ROM;
passing control to the instructions; and
responsive to a request implemented by at least some of the instructions, causing a premature timeout condition or a premature incipient timeout condition.
11 . A method comprising:
an act of modulating a signal onto an electromagnetic carrier wave impressed into a tangible medium, or demodulating the signal from the electro-magnetic carrier wave, the signal having computer instructions encoded therein, the instructions when executed by at least one computer causing said at least one computer to
become initialized by steps comprising the acts of:
detecting a presence of an option-ROM (Read-Only Memory) having a plurality of instructions encoded in the option-ROM;
passing control to the instructions; and
responsive to a request implemented by at least some of the instructions, causing a premature timeout condition or a premature incipient timeout condition.
12 . A method for initializing a computer comprising
means for detecting a keyboard status inquiry; and
BIOS-based means for causing a premature timeout condition or a premature incipient timeout-condition responsive to the detecting.
13 . An electronic device comprising:
at least one controller or CPU (central processor unit); and
a non-volatile memory having computer instructions encoded therein, the instructions when executed by the controller or CPU cause said controller or CPU to
become initialized by steps comprising the acts of:
detecting a presence of an option-ROM (Read-Only Memory) having a plurality of instructions encoded in the option-ROM;
passing control to the instructions; and
responsive to a request implemented by at least some of the instructions, causing a premature timeout condition or a premature incipient timeout condition.
