Re: Help with LiveCD/LIveDVD
Hi, sorry for the very late reply, but my obsd.misc mail folder has grown to 3000 mails during the last couple weeks while I was busy moving. Anyway, I'm as the original author of said page can confirm (sadly) that you might run into a (known!?) cdboot bug. For some reason cdboot can't boot a DVD exceeding a certain size and or containing more than a certain amount of files. There is a rather ugly, but at least working way around. Josh Grosse found it while building his live CDs, which can be found here, btw.: http://jggimi.homeip.net/livecd/faq.html The problem arouse with the KDE ones, the "solution" is to pack /usr/local into its own .iso (or perhaps a vnc mounted image would work as well) and mount it during startup. I did not build a LiveCD for a long time myself, but I hope too have "free time" coming up and will then update the instructions where necessary.

Re: Help with LiveCD/LIveDVD
Hi,
I hope you succeed. I'd be very itnerested in a live cd/dvd for obsd.
As you say, it's ideal to test hardware, but I don't have to time to
do it myself. Btw, why obsd 4.1?
Do you plan to upload the iso to some site? There were some projects,
like quetzal and olivebsd, but they died, I think.
good luck,
Pau

Re: Help with LiveCD/LIveDVD
cdbr is listed in the installation instructions as the cdboot loader. cdboot is the second stage boot loader IIRC. Don't hesitate to correct me if I'm wrong here. Oh, no, that sounds about right, I guess. The help is apprecitated. I'm not trying to make install media (that would actually be easy), just boot this liveCD. Has anyone else gotten a LiveDVD to work? Ted If you make a LiveCD (not DVD) does it work? The How-to says you can use this to build a LiveDVD. I thought that the bios booted the same if it was a dvd or a cd...? I really need the space a DVD offers. Does the CD boot loader have trouble with DVDs? Ted
Re: Help with LiveCD/LIveDVD
Just an update...it hangs on the message "Loading /CDBOOT" not cdbr as
previously posted. Sorry about that.

Hello all,
Please CC to me directly as I am offlist...
I am building a LiveCD/LiveDVD based on OpenBSD 4.1 snapshot. I know this
is an unofficial page, but I followed the instructions here:
http://openbsd-wiki.org/index.php?title=LiveCD
I'm using 4.1 because of the libraries required on the LiveDVD. This
LiveDVD is used for in-house hardware diagnostics with customized programs
written for BSD. I thought it would be easier to boot from CD rather than
installing OpenBSD on every machine we need to use as a hardware testbed.
The only changes I made to the above instructions were to copy the
"backup/{}" directories instead of tar'ing them and unzipping them.
Everything works fine until the hang on boot with the message: "Loading
CBDR.." The disc then fails to boot.

I'm burning a re-writable DVD using the above instructions
The mkisofs command to burn the image is as follows:
/usr/local/bin/mkisofs -no-iso-translate -R -T -allow-leading-dots -l -d
-D -N -v -b cdbr -no-emul-boot -c boot.catalog -o /tmp/livecd.iso /livecd
Any help would be greatly appreciated. I'm pushing against a deadline, so
any tips / pointers / suggestions are also appreciated.

Re: Help with LiveCD/LIveDVD
qemu doesn't work for some reason. Anytime I try and use qemu I get the error "Cannot initialize SDL library..." Yes, I have tried it in different hardware. What exactly do cdbr and cdboot do? I get the screen that says "OpenBSD boot loader" (with the hardware fd1 etc listed), with the "Loading /CDBOOT" above it and it just hangs. cdbr is listed in the installation instructions as the cdboot loader. cdboot is the second stage boot loader IIRC. Don't hesitate to correct me if I'm wrong here. The help is apprecitated. I'm not trying to make install media (that would actually be easy), just boot this liveCD.

Help with LiveCD/LIveDVD
Hello all,
Please CC to me directly as I am offlist...
I am building a LiveCD/LiveDVD based on OpenBSD 4.1 snapshot. I know this
is an unofficial page, but I followed the instructions here:
http://openbsd-wiki.org/index.php?title=LiveCD
I'm using 4.1 because of the libraries required on the LiveDVD. This
LiveDVD is used for in-house hardware diagnostics with customized programs
written for BSD. I thought it would be easier to boot from CD rather than
installing OpenBSD on every machine we need to use as a hardware testbed.
The only changes I made to the above instructions were to copy the
"backup/{}" directories instead of tar'ing them and unzipping them.
Everything works fine until the hang on boot with the message: "Loading
