Here is a duplicate of a response I've sent in the past. I suspect that it is the problem in your case. | This is probably the problem (the 5th slot, not the bus mastering). | | It has to do with PCI interrupt sharing. | | The PCI INT's are normally daisy-chained, and slots 4 and 5 (if 5 | is present) are expected to share: | | slot 1 slot 2 slot 3 slot 4 slot 5 | ,-. ,-. ,-. ,-. ,-. | INT A --|A|-. ,------|B|-. ,------|C|-. ,------|D|----------|D| | | | X | | X | | X | | | | | INT B --| |-' \ ,----| |-' \ ,----| |-' \ ,----| |----------| | | | | X | | X | | X | | | | | INT C --| |---' \ ,--| |---' \ ,--| |---' \ ,--| |----------| | | | | X | | X | | X | | | | | INT D --| |-----' `--| |-----' `--| |-----' `--| |----------| | | `-' `-' `-' `-' `-' | | By default, each PCI card will use the first interrupt connector, | which will be A, B, C, or D, depending on the slot (note: old PCI | hardware will *NOT* chain... it expects the boards to be jumper | configurable, or all boards to share INT A).
