I might be doing something wrong then. But after booting, I get
a whole slew of debugging:

	...
	ncr53c8xx: tpf = 137 scf = 4.0 xferp = 11 mhz = 1.825
	...
	
And then 

	scsi0: ncr53c8xx: port 0 irq 0 addr 0 size 0
	
and a config prompt. So it looks like it is scsi.c is calling
the ncr driver's reset, and the ncr driver thinks it succeeded.
However, I'm wondering about all the '0' values -- I don't know
if that is more of the same 'everything hidden by PCI' or not.

Once I enter the config info and type 'end' I get
	sysinit
	config w0
		devinit D6.0.0.0
	ncr53c8xx: 0: WDTN: target init 1
	ncr53c8xx: 0: WDTN: responding 1
	ncr53c8xx: 0: WDTN: response accepted
	ncr53c8xx: 0: SDTN: target init 12 15
	ncr53c8xx: 0: using 12 15
	ncr53c8xx: 0: SDTN: response accepted (status)
	D6.0.0.0 ready
	
which look like it just tried to access drive 0, but then it just sits
there. It doesn't access the disk, and doesn't print out anything else.

I've played around with the termination, and I'm sort of worried that the
system might not like me using a SCSI 1 cable to hook into an SCA->SCSI1
adapter on the seagate.

Anyone run into this before? Is it stalling on recognizing the hd?
