BIOS is the answer.

Sorry, that was "Have you tried just the following:"

It should not. COM32 is just more explicit. KERNEL needs to guess
what to load it as.

Herein lies the different architectures. Did you use
bios/com32/modules/pxechn.c32 with bios/core/pxelinux.0 ?
Also, is the PXE client on the same subnet as 10.14.141.150?
What PXE ROM is in use? An example would be the OROM from an Intel
Pro/1000 of a certain version or a Dell Optiplex 760 with BIOS A13
(which implies an Intel 82567LM-3 [8086:10de] and a particular ROM
