Hi,
I got a problem. I want to call the BIOS32 service of PCI device
ROMimage.I got the physical address of the BIOS32 sevice. But, how to
call the BIOS32 service on protect mode? I've tested to call BIOS32
service directly. But it always fail.

 __asm__ __volatile__( " call %%edi \n "
                                       : "=a"( ReturnCode )
                                       :
"D"(BIOS32_SEVICE_PHYSICAL_ADDRESS ),
                                         "a"( SERVICE_IDENTIFIER ),
                                       : "ax"
                                    ) ;


Can anyone help me? Any help would be greatly appreciated.

Best Regards,
