- /*
- * pxe.h for Etherboot.
- *
- * PXE is technically specified only for i386, but there's no reason
- * why we shouldn't make the API available for other architectures,
- * provided that someone wants to write the shim that allows an
- * external program to call pxe_api_call().
- *
- * We stick with Intel's data structure definitions as far as possible
- * on other architectures. Generally the only i386-specific stuff is
- * related to addressing: real-mode segment:offset addresses, segment
- * selectors, segment descriptors etc. We allow an architecture-
- * specific header to define these types, then build the PXE
- * structures. Note that we retain the names from the PXE
- * specification document (e.g. SEGOFF16_t) even if the architecture
- * in question doesn't represent a SEGOFF16_t as anything resembling a
- * 16-bit segment:offset address. This is done in order to keep the
- * structure definitions as close as possible to those in the spec, to
- * minimise confusion.
- *
- * This file derives from several originals. One is pxe.h from
- * FreeBSD. Another is general.h86 from netboot. The original
- * copyright notices are reproduced below. This entire file is
- * licensed under the GPL; the netboot code is GPL anyway and the
- * FreeBSD code allows us to relicense under the GPL provided that we
