coreboot accepts donations via the Software Freedom Conservancy through three different methods:
PayPal, check, and wire transfer.
Many companies will match donations made to a non-profit organization.
Please check with your employer to see if gift matching is a possibility.
Software Freedom Conservancy has a donation page where they describe the options to get money their way in detail. A few are also listed below for convenience, but their site is definitive.
To donate by check, make the check out to "Software Freedom Conservancy, Inc."
Place "Directed donation: coreboot" in the memo field.
Checks should be mailed to:
Software Freedom Conservancy, Inc.
137 Montague ST
Brooklyn, NY 11201, USA
Donors wishing to send money via a wire transfer should contact the SFC at firstname.lastname@example.org.
