The CentOS team is happy to announce the availability of CentOS-4.0 (RC1) for ia64. This product supports Intel Itanium2. Installation is tested only on HP rx2600, by me.
A bittorent for CD binary iso files is available from: http://beta.centos.org/centos/4.0beta/isos/ia64/centos-4.0-rc1-ia64-bin.DVD.torrent
The only way to download ISO's is via bittorrent. Please leave your download client running after the download is complete (with ports 6881-6889 open) as your client will become part of the peer to peer bittorrent network and reduce the load on our network mirrors. If you need some quick pointers for getting up to speed on bittorrent read: http://www.centos.org/modules/smartfaq/faq.php?faqid=24
NOTE: This is a Release Candidate distribution build and may not be suitable for use in production environments. We encourage you to provide feedback on this build via the Mailing Lists.
However, any errors or bugs you encounter should be reported to us via bugzilla on http://www.centos.org/bugs
RC1 - Expected life span is 14 days from Release. Within this time period we expect to move to a Final Release. Unless there are any urgent security issues, there will be no package update provided for RC1.
Known Issues include a problem with the serial console installation. I have not found the right combination to be able to install any 4-based version to rx1600 w/ only ttyS0. Will keep looking for this later.
