Well, I was talking using 16bit apps on computers there (y'know, the kind of laptops and desktops computers that are available today, in case YOU need me to define this further).
I kind of thought that this was obvious though.

Hey, it was a joke! ;)

But seriously speaking, we use almost every day a 16bit application: LILO. SYSLINUX or GRUB is 16bit too. Also, there is the infamous floppy BIOS update, running DOS (then 16bit).

And, I do not know how it is in other countries, but in Romania, the Ministry of Finance and the accountants use some applications written in FoxPro for DOS. I do not know what is so special about these applications, but this has opened a nice option of using Linux, accompanied by DOSEMU, as host operating system. :)

Although it seems strange, the 16bit applications have not yet disappeared.

hi,
Slackware64 can be turned to a multilib 32/64 system easily, as we all know.

But would it be possible to turn a Slackware32 into a multilib 32/64 system, without reinstalling to a slack64?

Maybe booting from a 64bit DVD, mounting the disk partition and upgradepkg-ing enough relevant packages?

Has anyone tried it and is willing to provide any info?
If I wanted to migrate from Slackware(32) in Slackware64, without reinstalling, I would do this:

I would boot from the Slackware64 installation DVD, I would mount the target partition to /mnt, then I would run from slackware64 directory:

Code:
ROOT=/mnt upgradepkg */*.t?z
Finally, I would do chroot in /mnt to fix the booting.

The multilib installation part starts after a successfully boot from a clean 64.

Hi,

I use to upgrade my Slackware systems (32bit-current and 64bit-current) with slackpkg. In my experience a large upgrade requires more time than a complete reinstall. In fact I've often reinstalled my systems and the challenge was to do this with a downtime as short as possible ;) (with a fast computer about 5 Minutes).

I'm sure this will run about 3-6 hours.

When I install the system, I download all packages with wget or rsync and create a minimal install-CD or bootable USB-device and chose to install from a premounted partition (where the downloaded packages are stored). It is important to make backups of all scripts one has changed (in my case wpa_supplicant.conf, rc.local)

Good point, BUT we talk about a 32 -> 64 migration, and I don't think that this system can be useful until the migration is finished. Just think that libraries paths differ between these operating systems, for example ...

Of course, the best idea will be an clean installation after the backup of useful data. :)
