SLC with 4.0.3c complains wants floppy disk? Should i use 4.1?

[Avi Freedman]

When I boot a 4.0.3 on an SLC over the ethernet, it tries to open
'fd0a' and wants a root device on fd0*.  Is this a problem with 
4.0.3 and the SLC?  I've heard that one should use 4.1 with it.
When I tried to boot off of a 4.0.3 tape, I got different errors-
it coldn't copy from tape to disk the miniroot (even though the
disk was set to scsi select 3 (for an SLC, the same as 0 for
the Sun 3's)).

Anyway, I was willing to believe a hardware problem until seeing
this error when booting over the network.  Also, when scanning for
devices, it complains twice, "fd: unexpectedly busy - stat 0xff' and
'Unknown machine type 0x54 in NVRAM' then 'Machine type set to
SUN4C_60'.

Thanks.  A summary on the 4/110 vs. SLC issue is forthcoming 
(I decided to get the SLC, obviously).
