Boot block jumpers
The boot block jumpers are used when updating the BIOS or BMC firmware in the unusual event that the boot block area needs to be updated. These jumpers are not used for routine firmware updates. Use the boot block jumpers only when the instructions with a firmware update specifically say to do so. When you do need to enable either of these features, use one of the spares from JP4 pins 1 and 2 or JP25 pins 7 and 8. The table below identifies the function of each pin pair on JP3.
