After blowing the dust off, here's what I see: A set of switches on the lower left, that selects the IO base address. I used 0x300, with means switches 1-8 up, 9&10 down. I believe the rightmost switches are the IO address with bits reversed. Next to the switches is a bank of 12 jumpers. From the left, the first 3 and the last three select the DMA to use - they have to match. The leftmost jumper is for dma 1, then 2 then 3. You have to find an unused dma channel. The middle 6 jumpers in the block are the irq select. From the left, these are 3,4,5,6,7,2/9. The single jumper just above the right side of the jumper block is marked "dr3en" on my board, presumably meaning "dma channel 3 enable".
