Congratulations!  I'm very glad someone has had some time to work on
the MMU code.

I would suggest getting either the floppy or ethernet driver working,
as both of them will be modifications of the SPARC/Intel code (chips
are the same, but DMA method is different due to DECstation hardware).

Another alternative would be a RAMDISK image loaded via the boot prom
tftp call...
