Canonical way to boot FreeBSD by hand, with no tools. Using one slice, one
partition
fdisk -BI /dev/da0
bsdlabel -Bw /dev/da0s1
newfs /dev/da0s1a
Making sure there's a /boot directory with the all important loader
Making sure /boot/kernel/kernel exists
This should boot -- however is pretty pointless without anything else.
init's needed, and everything else to make a full MUM (Multi User Mode)
environment...
Keep note that not only does the MBR need bootable code, so does the
bsdlabel/disklabel
newfs will set the proper fstype in the bsdlabel if it's partition is 'a'
Good luck... and yes, I top posted. (Deal with it, people who don't like
it...)

Hi,
I'm following Ceri's instructions for getting FreeBSD on a flash
drive. My laptop is a Feb 1 -current, I'm installing FreeBSD 7.1, and
the instructions are for 6.1, so we have all kinds of things that
could be going wrong.
The USB boots with the error:
F1 FreeBSD
F6 PXE
Boot: F1
Not ufs
Not ufs
No /boot/loader
When I investigated the flash's disklabel, I saw:
8 partitions:
#size offsetfstype [fsize bsize bps/cpg]
a: 4000106 16unused0 0
c: 40001220unused0 0 # raw part, don't
edit
I newfs'd this flash drive and put data on it. The obvious thing to
do is set the disklabel for partition a to 4.2BSD. Even if I have to
reinstall the data, no big deal.
So, run bsdlabel -e /dev/da0s1 and change the disklabel to:
#size offsetfstype [fsize bsize bps/cpg]
a: 4000106 164.2BSD0 0
c: 40001220unused0 0 # raw part, don't
edit
Then I get the error:
bsdlabel: Class not found
re-edit the label? [y]:
The same error appears if I try to edit the disklabel off-disk and
restore (-R).
Google tells me that this error is not uncommon, but the only
solutions I saw (loading geom_mbr and setting kern.geom.debugflags=16)
did not help.
Anyone have any suggestions? Or, can anyone tell me I'm running down
the wrong path?
Thanks,
==ml
