The problem we had seems to be due to an old version of EEPROM.
Check out the solution offered by David Moline...

Sorry for the delay in posting the summary. I did not get any responses
to my submission until after one week, apparently due to a delay in the
posting. By that time I had done the upgrade by building a sun4 client
on one of our IPX's and booting the 4/110 diskless. The client install
(on the sun4c IPX) procedure was painful because the add_client utility
would not acknowledege the existence of a sun4 kernel arch on the CDROM,
but that's grist for another post! Anyway, with the 4/110 booted diskless
it worked pretty much like the manual said it would. Thanks for all your

Here is the original posting:

 I have a Sun 4/110 series workstation running SunOS 4.1 which I was
 attempting to upgrade to 4.1.3 using the CDROM installation tools.
 I have upgraded a couple of SparcStations using the same equipment.

 I install the CDROM (ID #6) on the SCSI bus, along with the external
 SCSI disk/tape pack, where the bus terminates.

 At the monitor prompt I type:

> b sd(0,30,1) # this is what I should use on a sun4 (says the doc!)

 The various scsi peripherals make some grunt and groan a bit, after a
 minute the system responds with something like:

 scsi-select failed

 On a Sparc the command b sd(0,6,2) did the job. On this 4/110 I can still
 boot off the SCSI disk while the CD-ROM is attached, using the default
 setup and typing:

> b

 The adapter we have is "sw", described as 'SCSI wierd' in the kernel config,
 the sr0 device is listed in the messages and config file.

 Sorry, I don't remember the version of boot prom, but I recall seeing the
 year 1988 while watching the self-test.

 Thanks in advance for any help you can offer.

This is the fix I liked the best (a real spirit of hacking here!).
Wish I got it before I built that client. Thanks for the trick.

I didn't have a 'new mode' ;-( must be old ROMS
