Reset BIOS Password and Clear CMOS NVRAM Using CLR CMOS Button
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 - The simple memory test is performed only if Quick Boot is not enabled from the
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.

which clears the BIOS user and supervisor passwords.
You can also set or reset the BIOS password from the BIOS Setup Utility. See “BIOS Security
Menu Screen” on page 279 for more information.
Caution - Data loss. You should not perform this procedure unless instructed to do so by Oracle
