Intel® Server Board SDS2 Jumpers

The following tables describe each jumper options.

	Table 78. System Configuration Jumper Options
Option	Description
CMOS	When CN42’s pins 1 and 2 are OPEN (default), CMOS contents are preserved through the system
Clear	reset. When they are CLOSED, CMOS contents are set to manufacturing default during system
	reset.
Password	When CN42’s pins 3 and 4 are OPEN (default), the current system password is maintained during
Disable	a system reset. When they are CLOSED, the password is cleared / disabled on reset.
BIOS	When CN42’s pins 9 and 10 are OPEN (default), the system attempts to boot using the BIOS
Recovery	programmed in the Flash memory. When they are CLOSED, the BIOS attempts a recovery boot,
Enable	loading BIOS code from a floppy disk into the Flash device. This is typically used when the BIOS
	code has been corrupted.
BIOS Write	When CN46’s pins 1 and 2 are OPEN (default), BIOS boot block is protected from being updated.
Protect	When they are CLOSED, BIOS boot block can be updated
BMC Write	When CN47’s pins 1 and 2 are OPEN (default), BMC boot block is protected from being updated.
Protect	When they are CLOSED, BMC boot block can be updated.
Chassis	When CN50’s pins 1 and 2 are cabled to the chassis (default), a switch installed on the chassis
Intrusion	indicates when the cover has been removed. When they are CLOSED, the chassis intrusion feature
Disable	is disabled.
BMC	When CN49’s pins 1 and 2 are OPEN (default), the BMC enters operational mode upon the
Forced	negation of its reset. When they are CLOSED, the BMC enters force update mode upon the negation
Update	of its reset.
Mode
FRB3	When CN48’s pins 1 and 2 are OPEN (default), FRB operation is enabled. This allows the system
Timer	to boot from another processor if Processor 1 fails. When they are CLOSED, FRB2 and FRB3 are
Disable	disabled.
