-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Is there any reason why the keyboard poll routine (int 16h) in conio.inc checks fro a serial port. when pxelinux.0 is run under a vm - the keyboard does not register. which makes menus useless. Also the timer is broken. - -- regs MR E_T _______________________ \ \ \ OOHH I hate TYPOS \ \ \

From: Matt Fleming <matt.fleming at intel.com> Since we can't use __intcall() for EFI, and since we can now have the ELF module code resolve all our symbols at runtime, we should delete as many references to __intcall() as possible and just access the symbols directly. The most interesting patch is the support for weak symbols. We need to be able to reference derivative-specific
