I've been working with an old IBM PC (the original--2 floppies, monochrome
monitor, 256K memory, etc.) at work and I want to make sure the DIP
switches on the motherboard are set correctly.  I have no hardware
documentation, so can anyone tell me what the switches on each of the
two switch blocks on the original PC motherboard designate?  The only
ones I'm sure of are 5 and 6 on switch block 1, which set the video
adapter type.  I have no idea what the second switch block is for at all.
