This was in the 5.1 sysinstall notes. It is also mentioned on this site = (http://www.informit.com/isapi/product_id~{7309E848-0A1E-475A-A1CD-17B546= 2B1564}/element_id~{C8915938-27E4-4BF5-B449-CD40F6C9D8B5}/st~{FC01C6FA-A1= 66-40A9-BEFF-FA0234A128E9}/session_id~{D7D91592-81FC-47F8-BC69-313B51CAD0= D0}/content/articlex.asp)that was linked from freebsd.org. ----- Original Message -----=20 From: Jud=20 To: Adam King=20 Sent: Wednesday, July 16, 2003 11:10 AM Subject: Re: Multi-OS Boot Question On Wed, 16 Jul 2003 08:49:30 +1000, "Adam King" <aking@lgh.com.au> = said: > I currently have a dual boot Windows/Linux system and want to add = another > partition and install FreeBSD. >=20 > In the FreeBSD install, it mentions that the boot files must be = within > the first 1024 Cylinders.

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).) =20 > 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? 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. Jud
