1) If you join the list, continuing this conversation would be easier
in that others will more readily see your replies.

2) Could you provide version details?  Are you using the pre-compiled
pxelinux.0 and chain.c32 from the Syslinux 4.03 package?  If not, this
is probably my first suggestion.  Of course, if you have any other
modules from Syslinux, they should come from the same package/package
set.

This is indeed interesting.  Using "chain.c32 hd0 0" works while
"chain.c32 hd0" does not.  (These are just the one-line equivalent of
the LABEL you're probably using)

"keeps coming back to PXE."?  Do you mean that using "chain.c32 hd0"
just restarts the PXE boot?  If so, the BIOS is trying to be smart and
retry the boot rather than fail.

I have access to E6410s at work that I can try to check Monday.
