They're probably for a hard drive activity LED. Most Adaptec SCSI boards have four pins at the top of the board in the back (opposite from the L-bracket that screws into your case) that are for hooking up an LED. If you download the user's guide, and look on page 16 (page 22 in the PDF file), you'll see a mention of the LED connector: http://www.adaptec.com/pdfs/user_guides/19160_users_reference.pdf Most LED connectors in cases are only two pins, and since diodes only work in one direction, you have to generally try it out to see which direction will make it light up. > (I thought PCI cards was going to obsolete jumpers.. :-) Only for configuration. :) Ken -- Kenneth Merry ken@kdm.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
