Dualbooting pdaXii & OpenBSD: a mini how-to (for C3100/3200 only; do it at your own risk)[/span]
*******************************************************************************To set up a dualboot environment of pdaXii and OpenBSD, you have to do three things:
1. Flash pdaXii (in the usual flash "OK mode") & OpenBSD (in the emergency "D+B mode")
2. Modify /etc/rc.d/rc.rofilesys in pdaXii
3. Create a directory to hold the OpenBSD bootloader and kernel.*******************************************************************************1. (I suppose you know how to do this. If not, you'd better stop here for your safety.)2. Modify /etc/rc.d/rc.rofilesys in pdaXiiThis is how I change the
/etc/rc.d/rc.rofilesys in pdaXii (5.4.
(This also seems to work for other pre-Beta4 builds which uses the older bootloader, including Beta1 and Beta3, but YMMV):

Probably this is just a quick and dirty trick. I suppose there is a better way of doing that.
Anyway here is the full script.
[span style=\'font-size:12pt;line-height:100%\']USE IT AT YOUR OWN RISK! DON'T BLAME ME IF IT BRICKS YOUR BUDDY Z. [/span]
Two small notes:
-- In case OpenBSD fails to load for some reason, in the bootloader prompt (i.e., boot>), simply type
reboot and the system will boot into pdaX.
-- You don't actually have to type "openbsd" to answer the boot question. Just a [ENTER] will do.
3. Create a directory to hold the OpenBSD bootloader and kernel.-- Create a new directory under pdaXii:
mkdir /bsd-- Copy zboot and zbsdmod.o into this directory:
cd /WHEREEVER/YOUR/OBSD/FILES/ARE
cp zboot zbsdmod.o /bsdReboot. And then you'll see your glutton dog enjoy both penguin and puffyfish meat ...
