Well give these a try ..at ftp://204.57.142.148 in the pub directory
you will see a subdirectory named 'magnum'
inside you'll find two sub directories..floppy and floppy-ddb.
Both subdirectories contain an floopy boot image
(netbsd.ecoff is bootable) using the configuration file
listed below . The difference is one directory (floppy)
the ddb option was turned off when kernel was built,
the other turned on (floppy-ddb).
Now the netbsd.ecoff image file with the in-kernel
debugger is too big to fit on a floppy so I also
include a file called netbsd.strip where netbsd.ecoff
image was stripped... I found some 'arc' machines
will load a 'stripped' ecoff image and some don't
which is why I built on image without ddb (floppy subdirectory).
I hope one of these boot! The only thing I'm not
sure of is if the option COM_FREQ_MAGNUM=8192000
is correct... If wrong clock frequency you'll get nothing at all.# $NetBSD:
