Thanks for the info!
I'm going to attempt to boot a 'netbsd.ecoff'
Unfortunatly my HD on my DS is internal. So i will have to netboot the
kernel. This should be no problem , five minutes ago i netbooted a
half-working Linux/MIPS kernel over netboot, served from my Linux machine.
I'm still a little unsure about how im actualy going to get NetBSD
installed on the DECstation after I have booted the kernel. But I will
leave that question until i have sucessfuly booted 'netbsd.ecoff'
