Hi Bernd - Please try running the following command on your download: md5sum berkeley_upc-2.2.2-bin.iso (if you don't have an MD5 checker, you can get one here: http://www.fourmilab.ch/md5/) The result should match this: cea1ac52b51acaffda1f9a48e1000726 berkeley_upc-2.2.2-bin.iso and the file should have a size of exactly 809246582 bytes. I've just run this on our web server and verified the image is still intact (matches the MD5 checksum we generated at release time for the carefully-tested ISO). It's possible there's some incompatibility in your burning software - on Windows I'd recommend using Nero CD burner, although it should work with others as well. Be sure to use a dust-free, high-quality 700MB CD (old 650MB CD is too small) and possibly burn at lower speed in case your computer can't keep up. If things still aren't working for you, try downloading the tar-gzipped installer - which is slightly bigger (and doesn't fit on a single CD) but can be unzipped and used to install from a hard drive. If all else fails, you can download and install Cygwin yourself from http://www.cygwin.com/, ensure you install the required Cygwin packages (ash, binutils, gawk, gcc, gcc-core, grep, gzip, make, perl, tar) and then build Berkeley UPC runtime yourself from our source distribution. However, given the unfortunate day-to-day instability of Cygwin "releases", your mileage with this option might vary. Hope this helps... Dan
