BIOS Image Selection Jumpers
The Intel® Visual Compute Accelerator card includes three 16MB SPI Flash devices to store separate BIOS
images for each processor. Each flash device will store two BIOS images; a locked factory default image, and
a modifiable User Defined image. As shipped from Intel, both BIOS images for each processor will be the
factory default.
On the back edge of the VCA card is a set of three jumper blocks. Each jumper block is used to switch the
BIOS image for a given processor between the User Defined and the Factory Default. With the jumper in
place over the two stake pins (Default), the processor will boot using the User BIOS image. In the rare event
the User Image should get corrupted, the jumper can be removed to boot the processor using the Factory
Default image.
NOTE: All three jumper blocks should either be installed or removed together. At no time should one jumper
setting be different from the other two.
NOTE: The back edge of the VCA card includes several stake pins that are not used and have no functionality.
Care should be taken when restoring BIOS Image jumper blocks to their proper stake pin locations. See
