Ice And ABS (NO LBC)

I just traded my old 4x4 (No ABS) in for a new Toyota Tundra. The Tundra has
four wheel ABS. I've never driven anything with ABS in snow and ice as we
always took the old 4x4 when going to the mountains in the winter. My
question, are braking techniques on ice the same with ABS as without?, or do
you lock them up and let the ABS do it's thing?

TIA
