opterons can fully boot and run 32bit systems. As for mixing 32bit and 64bit: AFAIK you can't mix 32bit and 64bit code in the same process. Thus a 32bit binary needs a separate set of libraries. Other than that, it works just as well. -- Tzafrir Cohen +---------------------------+ http://www.technion.ac.il/~tzafrir/ |vim is a mutt's best friend| mailto:[EMAIL PROTECTED] +---------------------------+ ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
