Trying to install 2.0.2 on an AMD64.

Where are the INSTALL.* files for AMD64 hiding?

I can find

    ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.0.2/alpha/INSTALL.html

and siblings, but

    ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.0.2/amd64/

only has the binary and installation directories, no INSTALL.* files.

In ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.0.2/amd64/installation/floppy/
What is the difference between boot-com[12].fs and boot[12].fs ?

If the firmware is set to use a rs232 console, will the NetBSD kernel
also use a rs232 console?  Will it use the same baud rate, parity, and
such as the firmware?

Or is it going to try and use the video regardless?  If so, how
does one tell it what resolution one's monitor supports?
(640x480 is not supported)
