run "lsdev" to determine which bios device is your floppy (most likely
disk0), then run "load disk0:/amr.ko".  The loader will read ufs,
msdos, cd9660, and ext2 filesystems, so you could load the module from
any number of sources.  I don't know if the megaraid controller will
make your two disks visible to the host without you configuring them
for hardware raid, though.
