boot problem (stage 2 boot?)

[Sean]

Just installed on a new system and I am unable to boot.

Currently when that system boots it comes up with what looks like the 
following example from the handbook

 >> FreeBSD/i386 BOOT
Default: 0:ad(0,a)/kernel
boot:

from my reading this is a boot2 stage

booting from cd and going into Fixit it fdisk shows partition 1, 2, and 
3 unused, and Freebsd is on partition 4.
I thought it should be on partition 1?

Note: on install I choose the Standard boot manager.

I have tried playing with fdisk and disklabel to try to cure this 
problem, but continually get the example shown above.
With none of the above efforts working I have tried changing the boot 
manager and no luck, both by reinstalling and just by using sysinstall 
to modify the boot manager.I did get F1 FreeBSD when trying the FreeBSD 
boot manager option, but it still did not start the system.


Thanks
Sean
