ADD MULTI PLATFORM (PCBIOS/EFI/I386/X86_64) BOOT SUPPORT

[Harry Sharma]

PLEASE ADD OPTION FOR BOOT WINPE OVER THE NETWORK ON MULTIPLE PLATFORM : PCBIOS I386, PCBIOS X86_64, EFI I386, EFI X86_64. I TEST THIS OPTION IN TINYPXE IN WHICH YOU CAN SPECIFY MULTI BOOT FILE ACCORDING PROCESSOR ARCH.

[arch] 00006=ipxe-i386.efi
00007=ipxe-x86_64.efi 00009=ipxe-x86_64.efi

[arch] 00006=grldr 00007=bootia32.efi 00009=bootx64.efi
