OK, I have tried the following:
label WDS
menu LABEL ^4. Windows Deployment Service
com32 pxechn.c32
append wds01-sibptus.sibptus.transneft.ru::boot\x86\wdsnbp.com -W
and it *does* work for the majority of PXE clients. The packet dump is
here: http://zalil.ru/34637868
You can see from the dump that the client first queries DNS for the IP
address of wds01-sibptus.sibptus.transneft.ru (around frame 829) and
then downloads wdsnbp.com from 10.14.140.128.
This setup does not work on VirtualBox'es PXE client, perhaps because it
cannot do DNS lookups.
