Description

We are using iterate count max mode # (0x1ff) - min vbe mode (0x100) + 1 = 0x100.

If depth is unspecified, we walk down from 32 to 8, but fail to restart from initial farptr and zero safety counter for new depth.

Testing done: tested on system which only does provide 8-bit depth and failed to pick the mode before.
