making OpenBSD ISO's for the sparc

i'm lookin to make a sparc 2 an open bsd box.

i know that everyone is encouraged to buy the ISO's, but i rather try before I buy here. this is what i did with FreeBSD, now I buy all their stuff...

i've scoured the net on how to make an ISO, but I can't find a damn thing of use to me.

does anyone know of a good location where i can follow a step-by-step walk through that isn't overly complicated?

or maybe someone wants to tell me what to do?

i've downloaded the entire openbsd 3.3 sparc directory, now i dunno what to do with it.

-----------

i'm still looking... but still finding nothing. i've run across a few examples, but none of them seem to work.

let's start from this one.

the directory layout

openbsd
------->3.3
------->------->sparc
(place all the sparc files you find from say the openbsd ftp site here)

then you run mkisofs to make the iso...?

do any other files need to be included... or any other files put anywhere else...

and what options do i use with mkisofs? i'm trying the following and it keeps failing with the following error:

F:\openbsd3.3>f:\cdrtools\mkisofs -v -r -J -V "OpenBSD3.3" -b cd33.iso -c boot.catalog -o openbsd33sparc.iso openbsd
mkisofs 1.15a12 (i586-pc-cygwin)
Scanning openbsd
Scanning openbsd/3.3
Scanning openbsd/3.3/sparc
/cygdrive/f/cdrtools/mkisofs: Uh oh, I cant find the boot image 'cd33.iso' !

the thing is that cd33.iso is exactly where it should be... in /openbsd/3.3/sparc

-----------

alright... a bit of tinkering and i was able to create an ISO... dunno if it works. from the looks it it, it isn't.

this is what i used, the " -c boot.catalog " is what was giving me problems. i dunno why.

mkisofs -l -L -r -J -sparc-boot openbsd/3.3/sparc/cd33.iso -o OpenBSD33.iso -V "OpenBSD_3.3" -v openbsd

i booted on the sparc 2 by issued a "boot cdrom" at the ok prompt.

now i'm having a new problem... it seems that the CD wasn't made right.

i get the following error:

Bad magic number in disk label
Can't open Sun disk lable package
Can't open boot device
