This Amendment No. 6 (this “Amendment No. 6”) amends and supplements the statement on Schedule 13D (the “Schedule 13D”) by (i) Schaller Equity Partners, a North Carolina limited partnership (the “Partnership”); (ii) Schaller Investment Group Incorporated, a North Carolina corporation (the “Adviser”); (iii) Schaller Equity Management, Inc., a North Carolina corporation (the “General Partner”) and (iv) Douglas E. Schaller, a United States citizen (“Mr. Schaller”) (collectively, the “Reporting Persons”), relating to the common stock (the “Common Stock”) of Cardinal Bankshares Corporation (the “Issuer”).  Unless otherwise defined herein, capitalized terms used herein shall have such defined meanings as previously used in the Schedule 13D filed by the Reporting Persons on February 17, 2011, as amended on June 6, July 27, September 29 and December 29, 2011 and January 9, 2012.

As of February 24, 2012, as reflected in this Amendment No. 6, the Reporting Persons are reporting beneficial ownership of 151,267 shares of Common Stock (approximately 9.8% of the outstanding shares) (the “Subject Shares”).

Item 4.  Purpose of Transaction.

Item 4 is hereby amended by adding the following information:

On February 23, 2012, pursuant to Section 1.12 of the Amended Bylaws of the Issuer, the Partnership sent the Issuer a letter (the “Nomination Notice Letter”) indicating the Partnership’s desire to nominate the following five individuals to stand for election to the Issuer’s Board of Directors at the Issuer’s 2012 Annual Meeting of Stockholders, which the Reporting Persons understand is scheduled to be held on April 25, 2012 (the “Meeting”): Ms. Carol S. Jarratt and Messrs. T. Mauyer Gallimore, Bobby L. Gardner Sr., John Paul Houston and James W. Shortt (each, a “Nominee”, and collectively, the “Nominees”). The Reporting Persons believe that the Nominees are proven business and community leaders from the Floyd, Virginia area, and that each Nominee, if elected, would bring much-needed insight, accountability and fresh and relevant perspectives to the Issuer’s Board of Directors.

The Reporting Persons currently intend to conduct a proxy solicitation in support of their desire to elect the Nominees to the Issuer's Board of Directors at the Meeting.

A copy of the Nomination Notice Letter, which includes an indication from each Nominee of such Nominee’s willingness to serve if elected, is attached as Exhibit 99.5 to this Amendment No. 6 and is hereby incorporated by reference.

THIS SCHEDULE 13D IS NOT A SOLICITATION OF ANY ACTION TO BE TAKEN BY STOCKHOLDERS OF THE ISSUER. IF THE REPORTING PERSONS COMPLETE AND FILE A PROXY STATEMENT, STOCKHOLDERS ARE ADVISED TO READ SUCH PROXY STATEMENT WHEN IT BECOMES AVAILABLE, BECAUSE IT WILL CONTAIN IMPORTANT INFORMATION, INCLUDING INFORMATION RELATING TO THE PARTICIPANTS IN THE PROXY SOLICITATION. ACCORDINGLY, STOCKHOLDERS SHOULD RELY ON SUCH PROXY STATEMENT, WHEN AND IF IT IS PREPARED AND DISTRIBUTED, AND NOT ON THIS SCHEDULE 13D.  IF FILED, THE DEFINITIVE PROXY STATEMENT AND FORM OF PROXY WILL BE MAILED TO STOCKHOLDERS OF THE ISSUER AND WILL ALSO WILL BE AVAILABLE AT NO CHARGE AT THE SEC’S WEBSITE AT HTTP://WWW.SEC.GOV.

Item 7.  Material to Be Filed as Exhibits.

Exhibit 99.5  Nomination Notice Letter from the Partnership to the Issuer, dated February 23, 2012.
