1. An information handing system comprising:
- a processor;
a Random Access Memory (RAM) in communication with the processor;
a Basic Input/Output System (BIOS) in communication with the processor, the BIOS having a memory test pointer and a test block size indicator;
the BIOS operable to perform a Power On Self Test (POST) routine and further operable to test at least one test block of the RAM during at least one idle period during the POST routine.

Abstract
The present invention discloses an information handling system that reduces POST time in a boot operation. The information handling system includes a processor, a memory and a BIOS unit. The BIOS also includes memory test pointer and a test block size indicator. During the POST routine, the BIOS tests at least one test block during at least one idle period.

13. A basic input output system (BIOS) comprising:
-
a test pointer;
a memory test block size indicator having a pre-selected period;
a memory test block period indicator;
the BIOS operable to calibrate the test block size indicator for the pre-selected period prior to running a Power On Self Test (POST) routine; and
the BIOS further operable to test at least one memory test block during at least one idle period during the POST routine. - View Dependent Claims (14, 15, 16, 17)
