Any restrictions on how I divide the disk up? Yes. You must make sure that your root partition is below 1024 cylinders = so the BIOS can boot the kernel from it. (Note that this is a limitation = in the PC's BIOS, not FreeBSD). For a SCSI drive, this will normally imply that the root partition will = be in the first 1024MB (or in the first 4096MB if extended translation = is turned on - see previous question). For IDE, the corresponding figure = is 504MB. this answer is vague. does the root partition need to end below 1024 = cylinders also? i suspect i'll find the answer to be yes, but stating = it explicitly here would clarify things. (in any case, i see that my root partition is way outside off 1024 = cylinders, so this sort of answered my question anyway.) thanks for all the information! -jack ------=_NextPart_000_0006_01BCE097.B2517E60 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD W3 HTML//EN"> <HTML> <HEAD> <META content=3Dtext/html;charset=3Diso-8859-1 = http-equiv=3DContent-Type> <META content=3D'"MSHTML 4.71.1712.3"' name=3DGENERATOR> </HEAD> <BODY bgColor=3D#ffffff> <DIV> <H2>2.14.
