Hi, One of our customers uses INT 22h/AX=C to shut down UNDI interface. This interface is documented in http://www.syslinux.org/doc/comboot.txt. The excerpt is shown below: AX=000Ch [2.00] Perform final cleanup Input: AX 000Ch DX derivative-specific flags (0000h = clean up all) Output: None Apparently, device is not shut down based on the description of

...request (AX=0xc) at all. > > Can someone help to clarify this? comboot_call.c is part of gPXE/iPXE, which only supports a subset of the COMBOOT API. However, even if you are running on top of PXELINUX proper, the INT 22h interface is obsoleted in Syslinux 5+. Its direct replacement is the syslinux_final_cleanup() C API call, but perhaps you could give some insight in what your customer needs to do so we can advice if there is a better solution? -hpa

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
