Sept. 17 (Bloomberg) -- Internet-browser pioneer Marc Andreessen, who sold his software company Opsware Inc. to Hewlett-Packard Co. two years ago for $1.6 billion, joined the personal-computer maker’s board today.

Andreessen will begin serving on Hewlett-Packard’s board immediately, bringing its total number of directors to 11, the Palo Alto, California-based company said in a statement.

Mark Hurd, who took over as chief executive officer of Hewlett-Packard in 2005, has reshaped the board following an ethics scandal involving boardroom leaks to the media. Andreessen, 38, is best known as the co-founder of Netscape Communications Corp., which helped popularize Web browsers.

Andreessen was a founder and chairman of Opsware, which Hewlett-Packard bought in 2007 to expand its software business. This year, Andreessen started the $300 million venture firm Andreessen Horowitz to fund Silicon Valley startups. He’s also chairman of Ning Inc., a social-networking company, and serves on the boards of EBay Inc. and Facebook Inc.

Hewlett-Packard will pay Andreessen $100,000 a year in cash, as well as a stock package valued at $150,000 a year, according to a regulatory filing. He will also receive $10,000 a year for serving as chairman of the company’s Technology Committee and get the opportunity to buy discounted Hewlett- Packard products for donation to a qualified charity.

Previously, Andreessen served as chief technology officer of America Online Inc., which acquired Netscape. AOL later became part of Time Warner Inc.

Andreessen didn’t immediately respond to a message seeking comment.

Hewlett-Packard, the world’s largest PC maker, rose 7 cents to $45.71 at 4 p.m. in New York Stock Exchange composite trading. The shares have climbed 26 percent this year.

The company’s board also includes John Hammergren, CEO of McKesson Corp.

Bloomberg LP, or a subsidiary of the company, is an investor in the Andreessen Horowitz fund.
