Abstract
The invention introduces a POST (power-On-Self-Test) debugging method, executed by a processing unit, which contains at least the following steps. A phase number indicative of a current POST phase is set. A driver is selected from a scheduled queue. A GUID (Globally Unique Identifier) of the driver is obtained. The phase number and the GUID are stored or output, so as to recognize the phase of the driver being interrupted upon a break point of the driver. After that, the driver is executed.
Claims18
A POST (power-On-Self-Test) debugging method, executed by a processing unit, comprising:
- setting a phase number indicative of a current POST phase;
- selecting a driver from a scheduled queue;
- obtaining a GUID (Globally Unique Identifier) of the driver;
- storing or outputting the phase number and the GUID so as to recognize the phase of the driver being interrupted upon a break point of the driver;
- and
- executing the driver.
An POST (power-On-Self-Test) debugging apparatus, comprising:
- a volatile memory;
- and
- a processing unit comprising a cache, coupled to the volatile memory, setting a phase number indicative of a current POST phase;
- selecting a driver from a scheduled queue;
- obtaining a GUID (Globally Unique Identifier) of the driver;
- storing or outputting the phase number and the GUID, so as to recognize the phase of the driver being interrupted upon a break point of the driver;
- and executing the driver.
