I am very curious to learn just what it is that the jumper between the PCIe slots on an FMB-1102 motherboard does. I have searched high and low but cannot seem to find any refernce to it in any documentation. The dilemma is that my Hauppauge TV tuner card is not recognized in the Gen3 slots, but it is in the Gen2 ones. I have the current BIOS (3.88) and was inspecting my boaerd when I noticed this jumper. Wanted to know its function. Thought maybe it defined the cardslot parameters in some way. Any help?

i recommend you search the Service and Maintenance manual for guidance. Available in the Manuals section of the driver downloads pages for each product

pete914, is the Z620 jumper you are asking about located between the white PCI-32 connector and the black PCIe connector above it? Is it the jumper highlighted in yellow in the picture below?
If so, this is the E15 Boot Block recovery header. There is a jumper on pins 2 and 3 (right hand side pins in this picture).
Moving the jumper from pins 2-3 (default) to 1-2 manufally forces the system into boot block recovery mode. Starting the system with the jumper on pins 1-2 will cause the system to try to reflash the system BIOS from an attached USB drive. It will appear like the system is not booting, and there will be some keyboard flashes and maybe some screen prompts (It's been a very long time since I tried this).
If the system BIOS ROM is corrupted, the system will automatically go into boot block recovery mode. It can be forced into this mode by moving the jumper and then rebooting the system. If you system boots normally, do not move this jumper. Leave it alone.
Does this answer your question?
