I installed the 1.4.1PRE binary sets on my 3900 with the DSSI disks. The
purpose here was to test whether or not the system would "hang" in the MSCP
driver as it has on my uVAX3. However, I did in fact change two datapoints:
	uVAX3 has a third party MSCP disk controller and 1.4
	uV3900 has a KFQSA (DEC MSCP disk controller) and 1.4.1
One of the tests has always been building the kernel. Of course the 1.4.1
source sets are available yet so I used the 1.4 sets to build a new 1.4
kernel. (I suppose I could have slurped over the -current sources but I
didn't.) This is a good test because it beats pretty heavily on the disk
when run from disk. 

I am happy to report that the kernel built in just a few hours with no
hangs whatsoever. (Note this is still without swapping since the 3900 has
64MB in it)

The next step is to get the 1.4.1PRE binaries on to the third party disk on
the uVAX3 and try a kernel build there. In the past I have only been able
to build a kernel if there was no swapping and all disks were NFS mounted.
I'll let y'all know the results when they are in.

If I am successful, then I will fire up the uVAX II (KA630) with the same
3rd party ESDI interface and kick off a kernel build over the weekend to
see if that succeeds.
