WDS /Server 2012 PXE boot works fine with all my other hardware devices but not the Surface Pro, it Skips from Start PXE over IPv4 boot to Start PXE over IPv6 and does not boot.
The latest Surface firmware has been applied, both DHCP option 66(IP address of SCCM Server) & 67 (SMSBoot\x86\wdsnbp.com) are set. I have read the problem is due to the UEFI/Legacy BIOS devices cannot find the DHCP server so an IP Helper is required. we have applied 'IP Helper-address (DHCP Server IP address)' and 'IP Helper-address (SCCM Server IP Address)' to the relivent vLan.
Any advice on how to get Legacy and UEFI devices working simultaneously?
