Here are my findings regarding -current as of 1998-05-27 04:00 GMT.
(make world, config/make/boot new kernels).

I have tried "root on sd1s1a" (or "root on sd1a" or "root on sd1") with no
luck. These near-GENERIC kernels all panic with:
changing root device to sd0s1a
error 22: panic: cannot mount route (2)
Would I have had better luck by installing "dangerously dedicated?"

Booting with the "-a" (ask) options fails to ask. This includes GENERIC.
As sysinstall appears to install a GENERIC kernel, the installation
is not usable. Sysinstall should install a kernel capable of mounting the
selected root partition (sd1s1a) or, at the very least, warn the user that the
installation will not boot as installed.
I was successfully able to boot on second SCSI drive (target 1)
by hard coding the SCSI targets as follows:
config kernel root on sd0 # sd0 is second disk (target 1)
controller ahc0 # 7880/2940UW
controller scbus0 at ahc0
disk sd0 at scbus0 target 1 unit 0
disk sd1 at scbus0 target 0
disk sd2 at scbus0 target 4
disk sd3 at scbus0 target 5
device cd0 at scbus0 target 6
Of course I had do this while the drive was on target 0.
>Does anyone have any comments and/or suggestions?
Guess you were all waiting for me to post my configs/dmesg/mptable...
You'll note that I am now running SMP. However all of the above tests
was done using non-SMP near-GENERIC (modified "config kernel" entries).
As I'll building a similar configuration soon, I'd be willing to test any
relevant changes.
