Internal Connectors
The SPI Recover Jumper (J4) is used to select BIOS Recovery Flash
instead of BIOS Default Flash. By default the J4 is not installed.
It is recommended that Jumper is plugged to J4 only in case the
Default BIOS is corrupted, so that board is malfunctioning and do not
boot, or the Recovery BIOS is requested to be upgraded in order to have
sufficient or same support as the default BIOS.
In case Default BIOS seems corrupted then it is recommend to first trying
to use the Load Default BIOS Settings Jumper, see previous page.
When using customised BIOS it is recommended to upgrade both the
Default BIOS and the Recovery BIOS with the Customised BIOS.
