I managed to install syslinux-5.10-1.el7.rfx.x86_64.rpm

LABEL Windows Deployment Services pxechn.c32
   KERNEL pxechn.c32 10.87.0.202:boot\x64\wdsnbp.com

Gives me an error:

Attempting to load  "10.87.0.202:boot\x64\wdsnbp.com": 2:No such file or 
diractory USAGE:...

I tried
KERNEL pxechn.c32 10.87.0.202:\boot\x64\wdsnbp.com
KERNEL pxechn.c32 10.87.0.202::boot\x64\wdsnbp.com
KERNEL pxechn.c32 10.87.0.202:boot\x64\wdsnbp.com -W
KERNEL pxechn.c32 10.87.0.202:boot\x64\wdsnbp.com
