[CentOS] 4.4 i386 Server CD actually 64-bit?

Just downloaded the CentOS 4.4 i386 Server CD.  The md5sum on the file
matches:

  My file:         8ccb89265b16ca551bd04a15b3cf59a1 (CentOS-4.4.ServerCD-i386.iso)
  md5sum.servercd: 8ccb89265b16ca551bd04a15b3cf59a1 (CentOS-4.4.ServerCD-i386.iso)

However, when I boot up with the CD on a Compaq Armada E500 laptop (Pentium
III), the following message pops up:

  "Your CPU does not support long mode. Use a 32bit distribution"

If I use my regular CD 1 of the full i386 CentOS 4 install, I don't get this
and am able to get into the installer.

So is something wrong with the CentOS-4.4.ServerCD-i386.iso file on the
mirrors?

Thanks,
Ray
