Actually, there is mention of the computer warning at about the two
minute point in the narration of the video clip:

"... were warned by a Master Caution Light and Flight Control
Systems Caution 19 seconds after brake release, while on takeoff
roll. They observed air-data faults, but those faults resolved
themselves within six seconds, and the caution was rescinded at
approximately 120 knots indicated. But the airspeed numbers were
wrong. When the pilots thought they had 158 knots, they actually
had 124. With the false airspeed readings and faulty system that
was exaggerating their control inputs, the pilots never stood a
chance. ... "

Summary Of Facts

At the bottom of page 17 it states:

Within the B-2 community a defacto decision speed of 100 KIAS is
utilized to determine whether to abort a takeoff or to continue
into the air with an error, fault, or failure. In addition B-2
pilots distinguish between serious concerns meriting an aggressive
decision to abort a takeoff presented by a red Master Warning
light, and yellow Master Caution lights that are "analyzed" prior
to taking action. Since the yellow Master Caution, rather than a
red Master Warning, occurred after accelerating past 100 KIAS, the
MC did not reflexively initiate an abort....



Here's the USAF opinion on not aborting the takeoff:

http://www.acc.af.mil/shared/media/d...080605-058.pdf
Statement Of Opinion

MP1 asked Mishap Pilot 2 (MP2) for a takeoff/abort decision. At
approximately 120 KIAS, MP2 called "continue takeoff" as all
caution indications had cleared and the MA was above the briefed
100 KIAS "decision speed." Decision speed is the speed at which
pilots decide to continue the takeoff or abort. ...
