"should I use this to start the install and then use 2,3,4,5 cd of the 32-bit version ? "
NO! Suse 9.2 x86-64 does not come from suse or Novell on CD's -- only DVD's.
That said, if you have a dvd burner look here:
for a how to.
Then, if you can find 9.2 base somewhere, have a go
I just went to ftp://ftp.suse.com/pub/suse/x86_64
and apt for x86-64 -- base is empty. It usually takes 6-months to see a base release of the newest release -- or at the release time for the next upgrade.
Another way to go is do it go with 9.1 and update everything: I recommend buying the DVD because you get everything and FTP D/L is short on many things which you will have to find and install on your own.
last remark = bit-torrent, you have the site
