Bios Recovery Mode (J6B9); Table 53. Password Clear Jumper (J6B8) - Intel S2600KPFR Product Specifications

Configuration Jumpers
Jumper Position
1-2
2-3
This jumper causes both the User password and the Administrator password to be cleared if
they were set. The operator should be aware that this creates a security gap until passwords
have been installed again.
Note: No method of resetting BIOS configuration settings to the default values will affect either
the Administrator or User passwords.
This is the only method by which the Administrator and User passwords can be cleared
unconditionally. Other than this jumper, passwords can only be set or cleared by changing
them explicitly in BIOS Setup or by similar means.
The recommended steps to clear the User and Administrator passwords are:
Plug out the compute module and remove the air duct.
1.
Move the jumper from pins 1-2 to pins 2-3. It is necessary to leave the jumper in place
2.
while rebooting the system in order to clear the passwords.

and set the Administrator and User passwords if you intend to use BIOS password
protection.

7.5 BIOS Recovery Mode (J6B9)

If a system is completely unable to boot successfully to an OS, hangs during POST, or even
hangs and fails to start executing POST, it may be necessary to perform a BIOS Recovery
procedure, which can replace a defective copy of the Primary BIOS.
The BIOS introduces three mechanisms to start the BIOS recovery process, which is called
Recovery Mode:
