BeBox uses some PReP chips, but they do not yet support Open Firmware.
Their FAQ Web page says, "We don't yet use OpenBoot. We are actively
working to support it." They have a flash ROM, so hopefully existing
boxes will be upgradable through software. Let's cross our fingers and

Be would like to provide documentation to developers, but I am under the
impression that they are far too busy to be of much help right now. They
have a BeOS for PowerMac release to get out the door, and for DR9 they are
completely reimplementing the filesystem layer! The Linux port was during
a period of time when Be was far less frantic with their other deadlines,
and therefore able to support the porting team.

I believe so. I haven't tried Linux on BeBox yet. I have a 486 PC
running FreeBSD sitting next to the BeBox and connected by Ethernet, so
I'd rather run BeOS and telnet into a real UNIX box for the things I can't
do natively with BeOS (which has a POSIX layer in addition to a GUI and
native C++ API).
