[syslinux] Just one machine could not boot into PXE

[Greg_Chu at Wendys.com]

Hi, all,

I have successfully PXE boot 8 or 9 machines, do not remember when all of 
sudden one machine just hung on the menu. If I just use label then it 
boots into whatever the label directs. If I put default menu.c32 or 
vesamenu.c32 it just hung after loading the default.

Any one has a suggestion? since it worked before, I may just try the older 
versions for now to see if I can find one PXELinux version works.

Thanks.

Greg
