When using the 820982 “PCI Riser - Flex - 2slot w. arbiter” the BIOS option “PCI riser Support” shall be
disabled. Then the lower slot has IDSEL / IRQs routed straight through and the top slot has the routing:
IDSEL=AD22, INT_PIRQ#F, INT_PIRQ#G, INT_PIRQ#H, INT_PIRQ#E. 820982 PCI Riser shall be plugged
into Slot #1.
The BIOS option of “PCI riser Support” is for support of another type of dual PCI Riser module having one
PCI slot IDSEL / IRQs signals routed straight through and the other PCI slot routing: IDSEL=AD19,
INT_PIRQ#H, INT_PIRQ#E, INT_PIRQ#F, INT_PIRQ#G. Such a Riser card to be is not available from
Kontron at present time.
