 From the syslinux-6.01 distribution. Sorry, should have mentioned
that.

pxelinux.0

Well, how do I figure out?

$ md5  /tftpboot/pxelinux.0
MD5 (/tftpboot/pxelinux.0) = 3d5bf88dc0c7bb00d64864325dd83d32

It's from bios/core/pxelinux.0

Did it send a packet to 10.14.141.150?

Why did you write "COM32 pxechn.c32" and not "KERNEL pxechn.c32" Does
it make any difference?

I have also noticed that the syslinux-6.01.tar.gz contains several
variants of pxechn.c32, may I be using the wrong one?

bios/com32/modules/pxechn.c32
efi32/com32/modules/pxechn.c32
efi64/com32/modules/pxechn.c32
