Beware, though, that if the hard drive you boot from is a SCSI / SATA one too, you should take a special precaution -- either don't build the 'SCSI disk (sd) driver' nor your SCSI / SATA controller's driver built as modules (but rather "compile them into the kernel") or use the "initrd" feature. Otherwise you'll have a chicken-and-egg problem. Same warning goes about compiling your IDE drivers as modules, with the difference that IDE drives usually don't have a custom IDE Controller module.
initrd is how distros (RedHat, Debian and everyone else) make their kernel packages support all possible SCSI controllers without infinitely bloating the kernel with tons of drivers "compiled inside". Look up "initrd" for more info. If you decide to make your own initrd image with mkinitrd (it's easy -- but, as with all those kernel-compiling games, one mistake can make you rush for your rescue CD so have one handy), make sure your /etc/modprobe.conf contains: alias scsi_hostadapter yourscsicontrollermodule For example, my SATA hard drive sitting on an nForce 3 SATA controller, required: alias scsi_hostadapter sata_nv This "alias" line is how modern versions of mkinitrd determine what SCSI driver to pack into the initrd image they create.
