Which file? Find the file that matches your system version. A version with a name like RH72 is for RedHat version 7.2. The special version K24 is for the 2.4 kernel in general and this covers the Enterprise Edition 3 series. When in doubt about the proper version, just ask! ========================================================= The standard cpio command will sometimes fail on Linux systems due to a compatibility issue with the "c" option. When you download one of these distributions, first try: zcat filename | cpio -icmvdu (where filename is the name of the file that you have downloaded) If this gives an error about a bad or corrupted media, try the following variation instead: zcat filename | cpio -imvduH odc If there are still problems, contact customer support at 630/941-7767 or "support@computron.com"
