[9fans] SCSI query

[lucio]

I have the following SCSI configuration:

	0: wide
	1: wide
	2: narrow

off of an 53C8xx controller with only a narrow connector.

For some reason, Plan 9 does not see the wide devices although
seemingly the controller does: I have formatted them, apparently
successfully.

This is the startup dialogue, having enabled KPRINT in

	/sys/src/9/pc/sd53c8xx.c

I presume one can ignore unrelated exchanged info, but I've included
everything worth disclosing.

Thanks to anyone who can suggest how to sort this out.  I note that
NetBSD reports parity errors when starting up on the same hardware,
so the problem may be local.
