My apologies if some of this is already in the handbook... I wanted to
share an experience I had to save others a lot of time and frustration.

If you're wanting to use a disk that has, say 4096 cylindars in normal
mode, and you want to dual boot, you'll probably run into trouble.  In LBA
mode, you can often get the cylindars to be 1023, but FreeBSD's fdisk will
still detect the hard disk's native geometry.  For this reason, if you're
dual-booting and want things to actually work, you will need to set the
drive geometry to what your BIOS is using (in LBA mode) in the FreeBSD
fdisk.  If you don't do this, things will get fairly confused and you
won't be able to boot FreeBSD from the boot manager (but you probably will
be able to boot using a boot floppy and specifying the location of the

Also another pointer: when buying RAM, spend the extra money and get
parity RAM.  You may need to specify "True Parity".  There are goofy
parity RAM simms that have one extra chip that emulates parity
(essentially always setting correct parity) for boards that require parity
ram... don't buy these- they don't offer anything more than ordinary
non-parity simms.  I was having a severe problem with page faults at
inopportune times (ie, in kernel mode) and signal 11s all over the place,
which has now totally gone away since I replaced the non-parity ram (which
obviously has a few bad bits somewhere) with parity ram.
