FreeBSD 6.0 on Pegasos/ODW

[Matt Sealey]

Why isn't there an ISA bus attachment?

We have an ISA bus on the Pegasos (Via 8231 southbridge)

In all honesty the design of the system should be that while it there is
some grunt work required, it is much the same as in Linux - when the driver
doesn't exist on PPC you just symlink it from the i386 tree since all of
the hardware already works in FreeBSD on a PC. I used to run FreeBSD 5.1 on
a Via EPIA board, it had the exact same southbridge and peripheral chips
and ran like a dream. Endianness notwithstanding it should be the same
way.
