What is a "rollover"?
"eth" is ethernet?
You want to use ethernet cables for a serial connection?
I went to my Friendly Local Mom & Pop PC Shop
(http://www.gigaparts.com/) and said, "Gimme a null-modem DB9 female to
female serial cable." Made in China. About $6. Works great on the
standard Soekris external serial connector.
Digging at another local computer surplus store I bought a serial
pigtail for $1 or $2. There are two different ways commonly used to
wire these things. The 2nd serial port on the net4501 is wired properly
to use insulation-displacement crimp-on connectors with ribbon cable.
In other words, crimp a 2x5 10 pin 100 mil connector on one end then
pin 1 on the cable goes to pin 1 on the DB9 but cable wire 2 goes to 6,
cable wire 3 goes to 2, smoothly across like that alternating
On the external connector you should be able to watch the BIOS do its
thing at boot. If monowall has a login getty on /dev/ttyd0 then you
should be able to get in on the external connector. If a getty is on
/dev/ttyd1 you can use the internal connector with the above pigtail.
Soekris defaults to 19,200 baud, FreeBSD defaults to 9600. You might
have to switch gears when the BIOS hands things over to FreeBSD.
