How BIOS POST Memory Testing Works

The Oracle Database Appliance (original version) BIOS POST memory testing is performed as
follows:
1. The first megabyte of DRAM is tested by the BIOS before the BIOS code is copied from
ROM to DRAM.
2. After existing out of DRAM, the BIOS performs a simple memory test (where a write/read
of every location with the pattern 55aa55aa is performed).
Note -
Boot Settings Configuration screen. Enabling Quick Boot causes the BIOS to skip the
memory test.
3. The BIOS polls the memory controllers for both correctable and non-correctable memory
errors and logs those errors into the SP.
