I posted a request a while back to see whether the 4/60 (SS1)

could supported sync under 4.1.1. The manuals say that it is

enabled on all new systems EXCEPT the 4/60.

The best response came from Greg Earle, Sun Microsystems, Inc.,

 JPL on-site Software Support, earle@poseur.JPL.NASA.GOV,earle@Sun.COM

1. Does the 4/60 support sync scsi?

2. If so, why is it not turned on?

No, Synchronous SCSI is not supported on the 4/60 under 4.1.1. It *is*

supported on the 4/65. I don't know why specifically; probably either speed

or slightly changed hardware between the 4/60 and 4/65. Upgrade thyself (^:

>Does anyone know any way of turning on synchronous SCSI on a 4/60 under 4.1.1?

You can't. The SCSI driver looks at the CPU type in the i.d. PROM at boot

probe time to decide whether it can enable it or not.
