I tried what you advise, checking /etc/ttys, and changed "off" to "on", for
NetBSD 6.1_RC4 i386 and amd64 on 8 GB USB sticks, and tested the i386
installation on the old computer, succeeded in getting apparently 4 virtual
terminals, and the mouse worked in pkgsrc modular Xorg, which is often not the
If the mouse in X is dead, I might be able to use a keyboard-oriented window
manager like ratpoison but would still not be able to use many X-oriented
But the first virtual terminal quit responding to the keyboard, nothing showed
on screen. Exiting X, I got a dim screen, a bug in how NetBSD reacts with ATI
r128 graphics card.
I can access the NetBSD partition from FreeBSD for NetBSD 6x and HEAD, but not
netbsd-5 due to not being able to read the disklabel, installed by sysinst.
I also copied /usr/mdec/boot to /boot after seeing these files were different,
for netbsd-6 and HEAD where I could do this from FreeBSD. Maybe I also could
The USB stick that produces the green garbage is a Kingston Data Traveler 16
GB. FreeBSD can read and write it OK, even NetBSD 5.1_STABLE amd installed
from binary sets in summer 2011 didn't give me all those green error messages,
though it was buggy in other ways.
