[ipxe-devel] Issue with TFTP Windows

Good morning,

I have found an issue with windows TFTP loading an WDS image (wdsnbp.com).   It appears that the older version of IPXE included a "strip initial" function to make windows TFTP work with IPXE.  The newest version of source does not include this function.  I have added the old tftp.c (not sure of the date of download) file to the new source(pulled today) and rebuild the undionly.pxe binary and everything started working again.

#!ipxe
prompt --key 0x02 --timeout 5000 Press Ctrl-B for the iPXE command line... && shell ||
ifconf
dhcp
set net0
next-server 10.132.99.61
chain tftp://ch1infwds01.akunacapital.local/boot\\x64\\wdsnbp.com

Please let us know if we are using the incorrect syntax or if this should be included in the .c file.

Thanks,

Mike Brunetti
