I have a dedicated FreeBSD 5.1 server, and I am experimenting with a WinXP /
diskless-FreeBSD dual boot workstation.
I have followed the instructions in the handbook and I get to a point that
makes me think I have done somthing wrong with my diskless kernel.
The workstation boots with an etherboot floppy, finds the dhcp server and
downloads the kernel from NFS. It seems to contemplate loading the kernel for
about 5 seconds then reboots.
I have seen postings in the archives about recompiling the kernel with the
proper CPUTYPE in /etc/make.conf.
I have tried this and it makes no difference.
The only thing I have been considering is that I have a bunch of modules that
were compiled & installed w/o CPUTYPE=p3, as they were imported with
clone_root.
So the only solution I can think of is to recompile/install these modules with
the proper CPUTYPE, but I'm not sure how to have make installkernel put the
modules / kernel in /misc/diskless/boot instead of /boot?
I won't need to do this with userland, will I? This would make diskless
operation impossible for my situation.
Below is a more detailed breakdown of what I am trying to do and some pieces
of my config files.

-I have diskless root at /misc/diskless:
[cash@boxH50:~]# ls /misc/diskless/
bin conf kernel sbin tmp
boot dev mnt stand usr

-I compiled DISKLESS kernel like so:
make buildkernel KERNCONF=DISKLESS CPUTYPE=p3
#i also had CPUTYPE=p3 in make.conf
