Michael Brown 3b586c8e29 [pxe] Invoke INT 1a,564e when PXE stack is activated Invoke INT 1a,564e whenever a PXE stack is activated, passing the address of the PXENV+ structure in %es:%bx. This is designed to allow a BIOS to be notified when a PXE stack has been installed, providing an opportunity for start-of-day commands such as setting the MAC address according to a policy chosen by the BIOS. PXE defines INT 1a,5650 as a means of locating the PXENV+ structure: this call returns %ax=0x564e and the address of the PXENV+ structure in %es:%bx. We choose INT 1a,564e as a fairly natural notification call, using the parameters as would be returned by INT 1a,5650. The full calling convention (documented as per section 3.1 of the PXE specification) is: INT 1a,564e - PXE installation notification Enter: %ax = 0x564e %es = 16-bit segment address of the PXENV+ structure %bx = 16-bit offset of the PXENV+ structure Exit: %edx may be trashed (as is the case for INT 1a,5650) All other register contents must be preserved CF is cleared IF is preserved All other flags are undefined Signed-off-by: Michael Brown <mcb30@ipxe.org>		9 years ago
