macbook air and opensuse 11.3 live

Hi, somehow I am too stupid to run a live Linux on a Macbook air. I used both, an openSUSE 11.3-KDE Live-CD and a Live-USB key and tried several boot options.
(i) I held down “C” to boot from CD → didn’t work. It’s an Apple CD drive but came with an older Macbook air a few years ago.
(ii) Found the bootmenu by holding down the option (ALT) key. Neither Live-CD nor Live-USB were shown. You can only choose the harddrive (and available wireless networks).
(iii) “Command-Shift-Option-Delete” to boot from an external drive didn’t work either. I assume my USB key is an external drive, right?

I don’t want to install openSUSE on the mac I just want to run a live system from time to time. Therefore I want to bypass Boot Camp or rEFIt and that’s probably why I am stuck here. I wonder, if I really have to setup one of them to boot into a live system? The wiki article “openSUSE on a Mac” is under review right now, so I guess there must be someone out there who can help me out.
Any help is greatly appreciated. Thanks.

rEFIt actually is a nice addition to Mac, and will let you boot from the live disk or a flash drive quite easily. You don’t have to install openSUSE to make use of it. :slight_smile:

Also, it’s always a good rule of thumb to check the md5sum or sha1sum after downloading, and to burn at the lowest speed possible.
