About Flash PROM Jumpers
The system uses flash PROMs to permit the reprogramming of specific code blocks
that are held in non-volatile system memory, and to permit remote reprogramming
of that code by an authorized system administrator over a local area network.
Three jumpers on the main logic board affect flash PROM operation. The figure
below shows the jumper locations, and the table describes their function.
