2 * pxe.h for Etherboot.
3 *
4 * PXE is technically specified only for i386, but there's no reason
5 * why we shouldn't make the API available for other architectures,
6 * provided that someone wants to write the shim that allows an
7 * external program to call pxe_api_call().
8 *
9 * We stick with Intel's data structure definitions as far as possible
10 * on other architectures. Generally the only i386-specific stuff is
11 * related to addressing: real-mode segment:offset addresses, segment
12 * selectors, segment descriptors etc. We allow an architecture-
13 * specific header to define these types, then build the PXE
14 * structures. Note that we retain the names from the PXE
15 * specification document (e.g. SEGOFF16_t) even if the architecture
16 * in question doesn't represent a SEGOFF16_t as anything resembling a
17 * 16-bit segment:offset address. This is done in order to keep the
18 * structure definitions as close as possible to those in the spec, to
19 * minimise confusion.
