identifying installation dvd

Quick question -

I’ve just found an installation dvd of opensuse 11.0 that I created some months ago, but I can’t remember whether I opted for the 32-bit or 64-bit version. How do I tell which version is on the disk?

I thought it would be obvious once I stuck it in the drive and had a look at the filenames, but it isn’t…

  1. you could install it (for real, or run it in a VM) then run
    uname -a
    from a terminal and look at the output…
    (btw, if you try to install on a 32 bit machine but it won’t, it might
    be because it is a 64 bit DVD)

  2. you could search the mirrors for the install DVDs for 11.0 and
    compare size and/or md5sums…


Look at the file called “content”. It contains a line like this:

Further down it contains a series of lines like these:

This lot are from the 32 bit DVD. The giveaway bits are i586 from the DEFAULTBASE and i386 from the other lines. They indicate a 32 bit version.

The 64 bit version will be different, using labels like x86_64
