I'm trying to make a bootable OpenBSD CD image on Mac OS X Snow Leopard (10.6). Unfortunately, the expected route to success, download + burn with Mac OS X, does not result what seems to be a bootable CD.
I suspect the problem lies with the burning process with Mac OS X. I am downloading the images (install47.iso, cd47.iso and cdemu47.iso), and trying to burn them with Disk Utility, which I presume is the same as the Finder "Burn" command when you right-click on an ISO image. I've tried both methods of burning the ISO.
I've also tried creating .DMG files from the .ISO files in a few ways (e.g. copying the files, creating a read-only image from the contents of the ISO, etc.), and then burning those. As none of those attempts have proven successful, I won't repeat the details here.
That being said, I'm not certain the problem is with the burning process. The target machine is the only machine that I can test the boot-ability of the burnt CD is a Compaq Presario 5320CA (circa 2001). The BIOS from this machine certainly indicates that it can boot from CD, but it consistently displays the messages "Non-system disk or disk error.". I've tried burning several CD's, however, which I'd expect to eliminate error.
The target machine seems to be able to read the image fine once it boots into the currently installed operating system (i.e. Windows XP). The disc certainly seems readable.
I'd be very much obliged for any suggestions on how to burn a bootable OpenBSD 4.7 image from Mac OS X — or feedback and suggestions on what may be the problem.
Incidentally, I don't have Roxio Toast, and I would prefer solutions that do not involve buying it or other commercial packages. I'm investigating using cdrecord now, and if that proves successful I'll post results here.
Thank you.

You could also try using 'dd'... should work, though I'm not super familiar with using it on the mac.
