Firmware debug trace capture

A non-transitory computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by a computer, cause the computer to perform operations comprising:

• capturing a first debug trace statement during a boot sequence of the computer;
• writing the first debug trace statement to a first memory location during a pre-extensible firmware interface initialization (PEI) phase the boot sequence of the computer;
• copying the first trace statement from the first memory location to a second memory location;
• capturing a second debug trace statement during the boot sequence of the computer;
• writing the second debug trace statement to the second memory location;
• and
• copying the first debug trace statement and the second debug trace statement from the second memory location to a file.

A computing device, comprising:

• a processor;
• and
• a memory having computer-executable instructions stored thereupon which, when executed by the processor, cause the processor to perform operations comprising
• capturing a first debug trace statement during a boot sequence of the computing device,
• writing the first debug trace statement to a first memory location during a pre-extensible firmware interface initialization (“PEI”) phase of the boot sequence of the computing device,
• copying the first trace statement from the first memory location to a second memory location;
• capturing a second debug trace statement during the boot sequence of the computing device,
• writing the second debug trace statement to the second memory location;
• and
• copying the first debug trace statement and the second debug trace statement from the second memory location to a file.
