Whjat I am doing is installing the nitros9/6309 tree from that image to 
the nitros9/6309l2 tree on the main hard drive.  When that is done, I'll 
go and add those 3 modules to a boot disk and generate it on vdisk 127.  
Then at the same time, add myram.dr amd mr0.dd to another copy of that 
bootlist and put it on vdisk 129.  After verifying that both of those 
generated good bootfiles, I will "bootlink 129" and verify that my ramdisk 
still works, then "bootlink 127" and see if the sdc can be accessed.  
Hopefully without having to do a rescue in case either runs me out of 
system ram.  smap says the current bootfile has 12k free, but it is not 
contiguous and I cannot format a floppy.

Wish me luck, I may need lots of it. :)
