chain.c32 has a lot of BIOS-isms and probably isn't worth modifying.
I believe none of the chain.c32 options apply to a (U)EFI environment.

There is a patch I'm reviewing for a new module to chainload (U)EFI
but it needs a lot of style cleanup. The chainloading of (U)EFI
binaries should be a lot closer to how linux.c32 works though might in
the future contain (U)EFI-specific options.  See
