VBE Function failed

I am create a driver to get the Device ID, Vendor ID, LFB and VBE Mode. The driver that I create already get the Device ID, Vendor ID, LFB of the display adapters but don't get the VBE mode because the Int 0x10 is returning AL != 0x4f. This is the code with the VBE function returning an error:

What is wrong at this code???
