The trick is to know that the geometry you need to use is the geometry that
the BIOS is using. 
This may have NO RESEMBLANCE to reality

to see what it is, 
boot your install floppy with the -v option
and if it goes off the top of the screen, use <scroll-lock>
to freeze the screen and  th eup-arrow to go back up..
(<scroll-lock> toggles) on/off
this will print out what the BIOS thinks it is using, but FreeBSD
doesn't know which drives those geomotries correspond to as
it doesn't know which drive the BIOS calls C:

another trick is to zap the drive and put a small DOS partiton on it..
then boot FreeBSD. The kernel can use the DOS partition
to figure out the BIOS geometry when booting. You can wipe the DOS
partition off when installing as the figures have been read in..
One of the early versions of freeBSD got the Bios figures off by one 
in one place.. not sure which one..
