Hello

I am trying to install linux from a SCSI cdrom
hooked up to a DTC3150V scsi controller, which
according to DTC uses the ncr53c406a chip (which
is in fact the label shown on the chip on the 
board)

The card has no BIOS on board, has IRQ disabled,
and is "memory-mapped" at 0xD800. The "manual" sheet
mentions nothing about an I/O addr.

Using the ncr53c406a boot image, with

	"ramdisk ncr53c406a=0xD800,0"
or
	"ramdisk ncr53c406a=0xD800,254"

it is unable to detect the controller, reporting 

	"NCR53c406a: no available ports found"

I have also tried

	"ramdisk ncr53c406a=0x230,0"
	"ramdisk ncr53c406a=0x330,0"

both resulting in an infinite loop of diagnostic 
printouts. (unfortuntely wasn't able to capture
it since it was not even pass boot at that time)

Could someone please point me to the
appropriate documentations etc for the correct
boot prompt argument ?

Many thanks,
whay.
