Folks,

using today's version of sys/arch/sparc/sparc/pmap.c, NetBSD is
running fine on a Sun 4/490.  So, I will shortly enable the
`SUN4_MMU3L' option in the generic kernel configuration. I'd
appreciate it if people would check whether doing so does not
disturb operations on other sun4 & sun4c machines.

The machine I tested on runs off a SCSI disk on the VME `si' controller
using full DMA support. However, many 4/400 class machines have an
IPI controller for which we currently do not have a driver.

Volunteers for removing this omission please speak up.


Also, the on-board `ie' ethernet controller still does not work
on this machine, probably due to the absence of I/O cache support
which must somehow be wired to assist the `ie' DMA engine.

Any insight in this issue is also welcome..
