Intel® Server System SR1690WB TPS Appendix D: Jumper Block Settings and Usage
Revision 1.7 63
Intel order number: E72797-009
1. Power OFF the system.
2. Insert recovery media.
3. Switch the recovery jumper. Details regarding the jumper ID and location can be
obtained from the Board EPS for that Platform.
4. Power ON the system.
5. The BIOS POST screen will appear displaying the progress, and the system
automatically boots to the EFI SHELL.
6. The Startup.nsh file executes, and initiates the flash update (IFlash32.efi) with a new
capsule file (*Rec.CAP). The regular IFlash message displays at the end of the
process—once the flash update succeeds.
7. Power OFF the system, and revert the recovery jumper position to "normal operation".
8. Power ON the system.
9. Do NOT interrupt the BIOS POST during the first boot.
Reset BIOS Configuration (J1B4)
This jumper used to be the CMOS Clear jumper. Since the previous generation, the BIOS
has moved CMOS data to the NVRAM region of the BIOS flash. The BIOS checks during
boot to determine if the data in the NVRAM needs to be set to default.

ICH10R RTCRST# pin is pulled HIGH. Default position.
2-3 Reset BIOS Configuration ICH10R RTCRST# pin is pulled LOW.
1. Power down server. Do not unplug the power cord.
2. Open the server chassis. For instructions, see your server chassis documentation.
3. Move jumper (J1B4) from the default operating position, covering pins 1 and 2, to the
reset/clear position, covering pins 2 and 3.
4. Wait five seconds.
5. Remove AC power.
6. Move the jumper back to default position, covering pins 1 and 2.
7. Close the server chassis.
8. Power up the server.
The CMOS is now cleared and you can reset it by going into the BIOS setup.
Note: Removing AC Power before performing the CMOS Clear operation causes the system
to automatically power up and immediately power down, after the procedure is followed and
AC power is re-applied. If this happens, remove the AC power cord again, wait 30 seconds,
and re-install the AC power cord. Power-up the system and proceed to the <F2> BIOS Setup
Utility to reset the desired settings.
