FireBee

So far FreeMiNT 1.18 is working on the FireBee with some limitations.

Except these limitations it's installed like on any other Atari.

FreeMiNT is currently being fully adapted to the Firebee.

[edit] How to get the current partially patched FreeMiNT working on the FireBee

You must use FireTOS, not EmuTOS, as it's still impossible to run programs that contains 68k-instructions under EmuTOS on the FireBee.
The boot-resolution must be in 256 colours (use fireconf.cpx).
The "video" setting in xaaes.cnf works differently from any other Atari, maybe with the exception of Falcons with CT60, CTPCI and a Radeon-card fitted. It's easiest to take the videomode from [newdesk.inf]. Save the FireTOS desktop in the resolution you want to use. Load newdesk.inf into a text-editor and locate the line starting with #El This line contains a number of hexadecimal numbers. Numbers five and six (counting from 1) is the videmode. So if these numbers are e.g. 40 and 4f, the XaAES videomode is 0x404f.
It works best with cache-setting "Normal" ("TOS: Normal" in fireconf.cpx). I find the automatic disabling of the cache annoying and useless under MiNT.
