Re: Current kernel with http://gnats.netbsd.org/39965 and pmap patches

Ok, some good news mixed with bad...

The ATARITT kernel does not load, regardless of if anything is plugged into 
a serial port or not.  Just a blank screen after running loadbsd.ttp.

But the BOOT kernel does boot.  And I successfully installed the sets via 
CD-ROM!  The install completes successfully, but when the system is rebooted 
I just get "Halting..." after the memory test.  This is probably from the 
very first stage of the netbsd bootloader but I'm not really sure.  I didn't 
try doing a complete zero of the disk before the install -- it's conceivable 
that might help.

One issue that is probably minor...  When "/bin/sh MAKEDEV all" is running, 
I get "df: not found".  This does not stop the install though.  Probably the 
df binary just needs to be dropped onto the sysinst floppy.
