 ###What are the jumpers on the backplane  * [NetBSD/mvmeppc FAQ](http://www.NetBSD.org/ports/mvmeppc/faq.html)
   * [NetBSD/mvmeppc History](http://www.NetBSD.org/ports/mvmeppc/history.html)
   
 The jumpers on the backplane are for Bus Grant and Interrupt Acknowledge. Some  
 VMEbus boards, like disk controllers, do their own VMEbus I/O instead of using  
 DMA from the CPU. The I/O board requests control of the VMEbus, the arbiter on  
 the CPU board releases control of the VMEbus, and then the arbiter on the CPU  
 sends a Bus Grant signal down the backplane.  
   
 There are only 4 Bus Grant levels, and you can have several boards, on the same  
 Bus Grant level. The Bus Grant signal daisy-chains down the backplane through  
 each I/O board. If you have an empty slot you break the daisy-chain.  
   
 Backplane manufacturers put jumper pins next to the connectors so you can jumper  
 across empty slots. Unfortunately the jumpers may be to the right or left of a  
 slot depending on the manufacturer.  
   
 You may also find that some VMEbus boards don't pass on daisy-chain signals that  
 they don't use. This means that you may have to leave jumpers on even when a  
 board is in a slot.  
   
 If the boards are side-by-side without an empty slot between the CPU and the  
 VMEbus boards you may not need any jumpers. That might be worth a try.   
   
   
 ###History  
 Using NetBSD/prep as a base, NetBSD was ported to an MVME1603-051 by Steve  
 Woodford. The board was one of two donated to the NetBSD Foundation by Gan  
 Starling on the condition that a port be attempted.  
   
 Following receipt of the boards, and replacement of the VxWorks bootcode by a  
 PPCBUG image kindly provided by Motorola Computer Group, NetBSD/mvmeppc was up  
 and running multi-user within two weeks.
