On-board video disabling (PL19)
If you install a video adapter expansion card, the computer should
automatically detect this and disable the on-board video adapter. If
for some reason this does not happen, and you experience problems
with a newly-fitted card, you can manually disable the on-board
video adapter by removing the VGA jumper from jumper block
PL19.
Audio disabling (PL19)
The on-board audio system can be disabled by removing the AUD
jumper from jumper block PL19. Disabling the audio system frees
the interrupt and DMA channel used by that system (normally
IRQ5 and DMA1).
