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).
