The 32k limitation doesn't seem to be true.  The limitiation is architecture
dependent and the PC seems to have chosen infinite, though there is a
practical limit of (640-28)K because of where things get loaded.  I've
got 9load saying hello but it crashes when it jumps to 32 bit mode.
My forehead is getting bloodier by the minute.

I thought that PXE could only handle a 32-KB boot image. I have heard this
quite a few times. I read the standard years ago but was sufficiently
impressed that the standard was filed in the manner it deserved, so I no
longer have access to it.

Anyway, if my 32KB guess is true, you may have to have PXE load etherboot,
and then have etherboot load 9load in the way that you did last summer at
LANL.

See this: http://news.gw.com/freebsd.cluster/275 for a discussion of some
PXE limitations.

I just did some quick looking round and just about everything that uses
PXE uses it to boot a little stub thing (etherboot, etc.) that in turn
boots the real thing.

You may want to get etherboot, build it with the PXE options, and see how
far you get.
