Yet more information: Running pxelinux version 1.75 released 2002-06-14, using PXE version 2.0 build 78 with Intel boot agent 3.0.03. Bios version 1.02. Machines are identical except for hard drive size and the fact that the machines that wont pxeboot have 2 processors. --same bios, same pxelinux/syslinux version (getting info off the same server) same bootagent version same pxe version. Same redhat version (7.3 if I didnt mention it earlier) Still running headlong into a brick wall. ------------------------------------------------------------------------------------------------- The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.
