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simply (far) out of date: "modern" BIOSes haven't had the 1024 cylinder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. ;)

P.S. Please post below rather than on top of the message you're replying
to - helps readability, especially in long threads.

What FreeBSD install did you find this in? Installation below the 1024th
cylinder is not a requirement for either FreeBSD itself or for its boot
loader. (By "FreeBSD itself" I assume you mean the entire filesystem or
some sizable subset of it.) The 1024 cylinder limit is rarely
encountered these days because it is a consequence of an old BIOS that
doesn't use geometry translation. (Geometry translation is usually
associated with LBA (logical block addressing).)

Use any boot loader you like. Should work fine. The FreeBSD system I'm
using right now is installed on the second half of an 80GB RAID0 array.

Multi-OS Boot Question
I currently have a dual boot Windows/Linux system and want to add another partition and install FreeBSD. In the FreeBSD install, it mentions that the boot files must be within the first 1024 Cylinders. Is this a requirement for FreeBSD itself or just for the FreeBSD boot loader? If I use a linux boot loader (LILO or Grub) which doesn't have a problem with the 1024 cylinder limit, will it be able to boot FreeBSD if it's boot files are above cylinder 1024? ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
