I think on CentOS/RHEL it's because they dropped support for the 586 &
earlier processors. Linux wide there's been a general drop in support
for 386 class machines. Something to do with recent versions of glibc

If the I386 (or i686, never could figure out why the name change)
disk doesn't quite fit on the DVD+, and needs a DVD-, this might put
some folks at an inconvenience.
I wonder if the difference between fitting and not fitting is small

Hello,
I am trying to do an NFS install of CentOS 6 on a fairly old / generic machine
AMD Athlon XP 1700. I use the CentOS-6.0-i386-netinstall.iso burned to a CD to
boot the installation. Only / partition and swap (2 partition) is set on the
primary IDE harddrive. I have a PCI SATA card with a 2

If there was an automatic ban on List mail containing HTML parts, it is
likely the latest crap would not be distributed to everyone.
A possible test of the Content-Type: header for

Do this:
1. Make sure your Centos has two network card. One connected to
internet, one to local lan. Make sure the Centos can already browsing
internet.
Example internet: eth0 192.168.1.1
local: eth1 192.168.2.1
