Re: NCR53c8xx driver and multiple controllers...(not new prob)

[LA Walsh <law@sgi.com>]

Here is the 'alternate' output when the ncr53c8xx driver is
compiled in:

SCSI subsystem driver Revision: 1.00

Note how this compares to the case where the driver is a module:

(note scsi0 was an IDE emulation in this setup -- something also removed in
the above setup)

--------
	This is on a 4x550 PIII(Xeon) system.  The 2nd two 
controllers are on pci bus 1.  The boot disk is sda, which is off of
scsi2 in the working example, or scsi1 in the non-working example.

	It seems that compiling it in somehow causes controllers
1 and 2 (which are off of the 2nd pci bus, "1", to get missed during 
scsi initialization.  Is there a parameter I need to pass to the 
ncr53c8xx driver to get it to scan the 2nd bus?
