Can I boot a from a BIOS PXE server on a machine that is UEFI PXE only
Hi,
I am trying to boot off a server that only supported BIOS PXE clients. Have a new PC that now only supports UEFI PXE. Can I use iPXE to emulate a legacy BIOS PXE client on the new PC?

Thanks.

No, EFI firmware and PCBIOS is different platforms and you can not boot one from the other (except for a few buggy implementation)

But running PXE binaries from iPXE in efi mode is not possible regardless.

With that said you can have configurations that detects this, and also most kernels etc supports both.
