Abstract
A test mode initialization system includes beginning a power-on self-test (POST) wherein the POST may be performed to determine whether a system under test is in a quick test mode, and in response to being in the quick test mode, initialize only a portion of all memory in the system under test and initialize only a portion of a plurality of central processor unit (CPU) cores.
Claims20
A information handling system (IHS) manufacturing boot process system comprising one or more subsystems to:
- begin a power-on self-test (POST);
- determine whether a system under test is in a manufacturing quick test mode;
- and
- in response to being in the manufacturing quick test mode:
- initialize only a portion of all memory in the system under test;
- initialize only a portion of a plurality of central processor unit (CPU) cores in the system under test;
- and
- boot the system under test to an operating system in order to perform an manufacturing test, wherein the remaining portion of the memory in the system under test and the remaining portion of the plurality of CPU cores in the system under test are not initialized.
An information handling system (IHS) comprising:
- a multi-core central processor unit (CPU);
- a plurality of memory modules;
- and
- a manufacturing boot process system comprising one or more subsystems to:
- begin a power-on self-test (POST);
- determine whether the IHS is in a manufacturing quick test mode;
- and
- in response to being in the quick test mode:
- initialize only a portion of the plurality of memory modules;
- initialize only a portion of CPU cores;
- and
- boot the IHS to an operating system in order to perform an manufacturing test, wherein the remaining portion of the plurality of memory modules and the remaining portion of the plurality of CPU cores are not initialized.
A method to initialize an information system comprising:
- beginning a power-on self-test (POST);
- determining whether a system under test is in a manufacturing quick test mode;
- in response to being in the manufacturing quick test mode:
- initializing only a portion of all memory in the system under test;
- initializing only a portion of a plurality of central processor unit (CPU) cores in the system under test;
- and
- booting the system under test to an operating system in order to perform an manufacturing test, wherein the remaining portion of the memory and the remaining portion of the plurality of CPU cores are not initialized.
An information handling system (IHS) comprising:
- a multi-core central processor unit (CPU) including a plurality of CPU cores;
- a plurality of memory modules;
- and
- a manufacturing boot process system comprising one or more subsystems to:
- begin a power-on self-test (POST);
- determine whether the IHS is in a manufacturing quick test mode;
- in response to being in the manufacturing quick test mode:
- initialize only a portion of the plurality of memory modules;
- initialize only a portion of the plurality of CPU cores;
- report as initialized all of the plurality of memory modules, including the portion of the plurality of memory modules that were not initialized;
- report as initialized all of the plurality of CPU cores, including the portion of the plurality of CPU cores that were not initialized;
- and
- booting the IHS to an operating system in order to perform an manufacturing test, wherein the remaining portion of the plurality of memory modules and the remaining portion of the plurality of CPU cores are not initialized;
- and
- in response to not being in the manufacturing quick test mode, initialize all of the plurality of memory module and all of the plurality of CPU cores.
