** - Advertised in the manual, but did not appear to support 3C589B PCMCIA ethernet, and the standard PCMCIA support files weren't on either of the PCMCIA boot/root disks. There was no documentation for how to use the PCMCIA installation.
*** - Debian support for the Alpha, Amiga, and Atari is underway.
^ - Debian is working on a Sparc version, and Red Hat currently plans to do a Sparc version.

^^^ - Without version dependencies, since packages don't have versions.
