Yes, you're quite right about the statement from Tiemann-Urban (whom I'd
have expected to know better - glad I bought The Complete FreeBSD by Greg
Lehey rather than their book!) and I presume also about the sysinstall
documentation.  I found an additional case of the same in section 3.19 of
the FAQ on FreeBSD's web site.

However, look at the following from section 3.19 of the FAQ: "Note that
this is a limitation in the PC's BIOS, not FreeBSD."  The statement is
simply (far) out of date: "modern" BIOSes haven't had the 1024 cylinder
limit for years.  I personally haven't had a system with FreeBSD
installed *below* the 1024 cylinder limit for something like a couple of
years.  (Before my current RAID array, it was installed on the 2nd half
of a 40GB drive; before that, on the second half of a 20GB drive.)

So - install as you like, no worries.  Any problems, write back and tell
me I'm an idiot.  ;)
