install to external usb disk oops

[Bob Bagwill]

I successfully installed 1.5 to an external USB disk drive but during the  
"install boot block" phase, it overwrote the partition table and bootblock  
of my internal disk.  I thought I was careful to select /dev/da0 not  
/dev/ad0,
but who knows?  I recovered the partitions with gpart, but WinXP still  
doesn't boot successfully. :-(

If I'm feeling masochistic, I could try the install again, and see if the  
bsdinstaller did it.
