Possible? > Mostly. :-) I have the original disk from my laptop in and USB/Firewire enclosure. The original disk has windoze and Gentoo, with GRUB on the MBR. A new, replacement disk drive is now installed, and is FreeBSD only. It has the standard FBSD boot loader. When I power on the laptop, I get the ususal F1/F2/F3 and F5 prompts (three partitions on the internal disk plus the USB/Firewire disk). Selecting F5 will put me into the GRUB menu, which will boot Gentoo. Mostly. I do not believe I have a SCSI driver in the Gentoo kernel, so the boot process crashes when Gentoo attempts to mount the boot device. It is my belief that were I to swap the drives, rebuild the kernel, with a SCSI module included, swap the drives back, I should be able to boot Linux from the external drive. It is not clear if I can boot windoze, as it should have a SCSI driver available to it (although who is to say, given the "customized" laptop installations these days), but it does not boot, despite my telling GRUB to map ad0 to sd0 and map sd0 to ad0, which *should* put the windoze drive on the first disk, at least as far as windoze knows. This is repeated in several sites I have searched, but none of them are using the FBSD bootloader initially, so that may be confusing things. I suppose I could install the GRUB boot loader in the ports, but I am going to "correct" the windoze issue with qemu.
