Are you sure it's 200MHz? A friend of mine has Solaris 9 installed on
his 270MHz Ultra, and I'm pretty sure when we checked the executables
in userland, they were 32-bit. Also, Sun's "officially supported"
version of Linux (Debian) runs all the ultrasparcs with a 32-bit kernel
and 32-bit userland.
In any event, after many hours of experimenting on my Ultra, I believe
I've discovered a (relatively) simple way to install a 32-bit kernel
and userland. Maybe this could be a FAQ somewhere on the NetBSD web
1) Install the 64-bit miniroot filesystem on a disk partition (I used
the swap partition)
2) Boot the miniroot off the miniroot partition, and install NetBSD
normally (with 64-bit kernel/executables)
3) After sysinst is finished and returns you to a shell prompt, start
it up again
4) Now tell it you want to install/upgrade. When it asks you where to
get the binary sets from, specify a directory
containing the 32-bit binary sets.
5) Once this second install is finished, return to the shell prompt,
mount the root filesystem on /mnt, and replace the
kernel with the 32-bit sun4u kernel from the NetBSD ftp site.
6) Reboot your machine, and you should be running a 32-bit
kernel/32-bit userland on your Ultra.
While it may be that running in 64-bit mode is the right way to go down
the line, until more of the pkgsrc sources I depend on (like cyrus and
apache-ssl) work in 64-bit big-endian mode, I'm stuck running in 32-bit
mode. Given all the compiler warnings I saw scroll by when I was
trying to get these (and other packages) working in 64-bit mode, it
looks like it will take quite a bit of work to get them all
