Thanks Manuel and Blair.

I was curious to know how you might put some other files on the boot 
CD, perhaps the NetBSD source, or whatever was convenient. 
Admittedly that's a problem easily solved by putting the source onto 
a second, normal CD.  A better example might be to make a CD from 
which you can boot and install, say, port-alpha, port-sparc and 
port-amd64.

By the way, I suppose it would be possible to make a CD which would 
boot an i386 with an i386 install kernel and also an amd64 machine 
with an amd64 install kernel?  Are the boot loaders the same for both 
ports?  If so, you could make it boot into the i386 install kernel by 
default, but if you stopped it during the five second countdown 
before the kernel had begun to load and told it to boot from an amd64 
install kernel, e.g.:

>  boot cd0a:netbsd.amd64

you could proceed with an amd64 installation. Is that correct?

Of course it would be much easier to use a different boot CD for each 
port, I was just wondering how it worked.

No doubt the kernel in amd64/installation/cdrom/boot.iso would be suitable?

By the way, is it possible (or easy) to reassemble the single file 
system image contained in 
amd64/installation/floppy/{boot1.fs,boot2.fs,boot3.fs} which could be 
mounted using:

# vnconfig -c vnd0 boot.fs
# mount_ffs /dev/vnd0d /mnt


There are instructions for making a kernel containing a ramdisk here:

http://netbsd.org/docs/guide/en/chap-misc.html#chap-misc-creating-bootfloppies

but they don't work in a source tree after building an amd64 release 
(not in the sources I CVS updated on 21 June anyway):

Is it possible to tell make to use the amd64 tools instead of i386 
ones?  I built the release using:

# pwd
/usr/src
# sh -c '/usr/bin/time ./build.sh command: ./build.sh -D 
../DistribDir -R ../ReleaseDir -O ../obj -T ../tools -x -m amd64
