WASHINGTON — Intel agreed to change some of its practices to settle a federal antitrust lawsuit alleging a decade of abuse.

Intel is calling a truce in one of its last major antitrust battles over its behavior in the market for computer chips.

The settlement with the Federal Trade Commission announced today extinguishes the harshest lawsuit Intel has faced yet from government regulators, who have accused the world's biggest semiconductor company of illegally bullying computer makers and sabotaging rivals to protect its dominance.

Intel has been slapped with a $1.45 billion antitrust fine in Europe and separate cases in South Korea and New York state, all of which it is fighting.
