No I have only one set of jumpers, as others pointed out and the IRQ is
set by SCSISelect and not by jumpers.

Yes it could but the only conflict I can see is with the PS/2 mouse that
uses IRQ 12 by default.
I don't tink it clash with PS/2 mouse because I have not such a mouse and
the support for it is disabled in the mobo BIOS. To confirm that IRQ 12 is
free, I can see that the other SCSI ctrl I have (a PCI ncr53c810) is using
IRQ 12 at boot (okay, remapped after the boot, but the PCI BIOS assign IRQ
12 to the device).
I am confused, but IRQ 10 works :)
Ciao,
Riccardo.
