Sorry about that last post.

I am experiencing the same problem as Mr. Suter.  My system:
	ASUS P90 (PCI/I-P54NP4) mainboard
	Award Modular BIOS V4.50G, #401A0-0201 with NCR PCI SCSI BIOS
	 V3.04.00
	GA-410 PCI SCSI card with NCR 53c810 chip, set to INTA and
	 IRQ 9 per mfr. instructions

Observed behavior:
	NCR BIOS correctly shows SCSI devices on startup
	DOS access works fine (of course, DOS probably doesn't use ints)
	DOS based NCR CAM driver reports IRQ=00, DMA=0 when loaded
	Linux boot gives same IRQ 0 message reported by Mr. Suter, with
	 exception of memory 0xfc000000, io 0xd000
	
I had tried all of the posted tricks, including boot parameters, IRQ
changes for assignment and level/edge, write buffer and burst disable/
enable, to no avail.  It is now quite apparent that the BIOS is not
providing proper parameters for the driver.

Can anyone tell me how to contact Award Software for a flash BIOS 
upgrade?  I would be so much happier to see the proper IRQ reported and
then have the boot hang (as reported elsewhere) than have Linux merrily
start without the drive ;)  Guess I'll have to hack the driver either
way.
