The requirement is to collect video controller information using Video
BIOS VBE3 in x86_64 Linux OS. The Bios Interrupt routine 0x10 is meant
for Video system. Right now, my application uses LRMI library to make
BIOS routine call 0x10.
But this 32 bit application is failing in x86_64 while making call to
BIOS routine.

Hence, I have started porting the application to x86_64 machine. But,
I am struck up with finding LRMI equivalent in x86_64 platform.
Could you please help me.

Thanks a lot.
