Tyan S4881/SCSI/FreeBSD 7.x

[Michael L. Squires]

Is anyone out there using a Tyan S4881 (quad Opteron with 2 PCI-Express 
slots, not the S4882 with only PCI-X and PCI slots)?

I have a system running 7.3-STABLE (see below) with an LSI 300-8X (PCI-X 
with 8 750GB Seagate ES drives) but I'm unable to add a SCSI controller to 
any slot.

Any attempt to add a SCSI card gets the following error (example is with 
an LSI 53C1010-66 66Mhz PCI-X in a slot set at 66MHz by jumper).  I've 
tried a PCI-E card (PERC4e/DC BIOS H430, configures correctly) with the 
same error but different device (OE) number.  I don't see anything obvious 
in the BIOS configuration pages>

I did see one error message (since lost) that indicated the PCI-X slot was
hardwired to an IRQ that did not match the one selected by the SCSI card,
but there is no obvious way to change either IRQ.

BIOS error message:

System Configuration Data updated
ERROR
Warning: IRQ not configured - PCI Mass Storage Controller in slot 03 Bus:11, Device:03, Function:00
LSI 53C1010-66

(I also have two systems with S4882 boards, no such problems; I'm about to 
replace the S4881 with a spare S4882).
