Just installed b7 using the latest (0.5) physwrite onto a disk.  I was 
sure to use the -u flag since it was over 800 mb.  When I attempt to 
boot my old clunker off this hard drive, I get a message that says

error 1 lba 22282238
error 1 lba 22282238
No /boot/loader

FreeBSD/i386 boot
Default: 0:ad(0,a)/kernel
boot:
error 1 lba 22282238
No /kernel

My disk is recognized as primary master, with no other IDE devices 
attached.  I tried fiddling with some bios settings for lba mode and 
block mode, but none of those seemed to work.  Any ideas?
