I tried replacing msdos1 with msdos3 since my bsd is on the third primary partition, but same result. I have checked the syntax several times. Does this error have to do with my placement within the file (near the end before memtest) or another error? Many thanks!

You might have to mark the partition as active/bootable and you might
have to hide other partitions.

It all depends on what the bsd is expecting to find in regards to
partitions. I've never used it so I can't be of much help besides guesses.
