I try to use grub as general PXE solution for UEFI systems, but fint it impossible to chainload to efi files located on Windows TFTP servers, since they operate with back slashes in their paths instead of forward slashes.

For example:

 set root(tftp,192.168.2.3)
 chainloader smsboot\\x64\\wdsmgfw.efi

or

  chainloader (tftp,192.168.2.3)smsboot\\x64\\wdsmgfw.efi

both result in "error: invalid EFI file path".

Manual "get  smsboot\\x64\\wdsmgfw.efi " with any tftp client works.

Moving the file over to a *ix server and use backslash works, it will load the file.

In general, I think it is wrong to validate path strings on TFTP servers.
