My on-board NCR-SCSI-Controller (NCR 53C810) isnīt detected with Linux 2.0.29
(german distribution from Delix (DLD 5.2)). With Linux 1.2.x (DLD 2.1) there
are no problems.
My mother board is a SA486P AIO-U (STD) with Phoenix BIOS, bought in 08/94).
Its PCI bridge is jumpered to IRQ 15 and INT A.

Please verify that the correct IRQ is being used for your board,
and that the motherboard IRQ jumpering matches the PCI setup on
PCI systems.
If you are using a NCR53c810 board in a PCI system, you should
also verify that the board is jumpered to use PCI INTA, since
most PCI motherboards lack support for INTB, INTC, and INTD.
