Is there a DOSBOOT.COM for amd64?

Is there a DOSBOOT.COM for amd64?  I believe DOS can run on amd64 CPU, so
there is the possibility of booting a 64-bit kernel from DOS (or running
LOADLIN, though that is for Linux and not NetBSD).  So this question is not
totally crazy, though I believe I didn't find any dosboot.com when I browsed
the ftp server under amd64.  I can't say if DOSBOOT.COM from i386 would work
on amd64 with a 64-bit NetBSD kernel but would say no if I had to guess.
