An apparatus and method provide supplemental support to an electronic card from above, such as along a longitudinal edge of a PCI card opposite an edge connector on the motherboard. The supplemental support may be provided at any of a plurality of locations along the edge of the card, to avoid interference with certain features on the card and to accommodate cards of a variety of shapes and sizes. One embodiment provides a support apparatus that includes a track secured to the computer chassis over the card, and is generally aligned with a longitudinal edge of the electronic card. A collar is disposed on the track and is moveable to any of a plurality of positions along the track. A plunger is inserted through the collar and is movable with respect to the collar into engagement with the longitudinal edge of the electronic card. A first locking member is activated in response to inserting the plunger into the collar to prevent relative movement of the collar and the plunger with respect to the track. A second locking member locks the plunger with respect to the collar when the plunger engages the card.

What is claimed is: 1. An apparatus for supporting an electronic card in a computer chassis, comprising: a track secured to the computer chassis over the electronic card and generally parallel with a longitudinal edge of the electronic card; a plunger support member secured to the track and moveable to any of a plurality of positions along the track; a plunger movably secured to the plunger support member and movable with respect to the plunger support member into engagement with the longitudinal edge of the electronic card for structurally supporting the electronic card; and a first locking member activated in response to positioning the plunger on the plunger support member for preventing relative movement between the plunger support member and the track. 2. The apparatus of claim 1, wherein the first locking member comprises a plurality of teeth on one of the plunger support member and the track and at least one opposing tooth on the other of the plunger support member and the track, wherein the plurality of teeth interfere with the at least one tooth to prevent movement of the plunger support member along the track. 3. The apparatus of claim 2, wherein the at least one tooth is disposed on a leg of the plunger support member, wherein the leg is urged outwardly in response to supporting the plunger on the plunger support member to move the at least one tooth into engagement with the plurality of teeth. 4. The apparatus of claim 1, further comprising a second locking member for preventing relative movement between the plunger and the plunger support member. 5. The apparatus of claim 4, wherein the engagement of the plunger with the electronic card activates the second locking member. 6. The apparatus of claim 4, wherein the second locking member comprises a plurality of teeth on one of the plunger support member and the plunger and at least one opposing tooth on the other of the plunger support member and the plunger. 7. The apparatus of claim 6, wherein the plunger comprises a sloping electronic card engagement portion that urges the plunger against the plunger support member in response to engagement of the plunger with the electronic card to engage the plurality of teeth and the at least one opposing tooth of the second locking member. 8. The apparatus of claim 6, further comprising a relief groove behind a electronic card engagement portion of the plunger for allowing the electronic card engagement portion to flex in response to engagement of the plunger with the electronic card. 9. The apparatus of claim 1, wherein the track comprises a pair of parallel, spaced rails, and wherein the plunger support member is slidably supported between the parallel rails. 10. The apparatus of claim 1, wherein the electronic card comprises a PCI electronic card. 11. An apparatus for supporting a plurality of electronic cards in a computer chassis, comprising: a plurality of tracks secured to the computer chassis over a plurality of electronic cards, wherein each track is generally aligned over a longitudinal edge of a associated one of the electronic cards; a plurality of independently moveable plunger support members, each movably secured to an associated one of the tracks and moveable to any of a plurality of positions along the associated track; a plurality of plungers, each movably secured to an associated one of the plunger support members and movable with respect to the associated plunger support member into engagement with the longitudinal edge of the associated electronic card for supporting the associated electronic card; and a first locking member associated with each track and activated in response to positioning the plunger on the associated plunger support member for preventing relative movement between the plunger support member and the track. 12. The apparatus of claim 11, wherein the plurality of electronic cards are generally parallel with each other electronic card and the plurality of tracks are substantially parallel with respect to each other electronic card. 13. The apparatus of claim 11, wherein the plunger support member comprises a collar for receiving the plunger. 14. A method for supporting an electronic card in a computer chassis, comprising: providing a track on the computer chassis over the electronic card in general alignment with a longitudinal edge of the electronic card; positioning a plunger support member on the track at a selected one of a plurality of positions along the track; movably securing a plunger on the plunger support member and moving the plunger with respect to the plunger support member into engagement with the longitudinal edge of the electronic card to support the electronic card; and locking the plunger support member to the track in response to supporting the plunger on the plunger support member for preventing relative movement between the plunger support member and the track. 15. The method of claim 14, further comprising: identifying a feature to avoid on the electronic card; and positioning the plunger support member on the track at a position such that the plunger avoids the feature to avoid when moved into engagement with the electronic card. 16. The method of claim 14, wherein the step of locking the plunger support member to the track comprises urging a plurality of teeth on one of the plunger support member and the track into engagement with at least one opposing tooth on the other of the plunger support member and the track. 17. The method of claim 16, wherein the step of urging the plurality of teeth into engagement with the at least one opposing tooth further comprising urging a leg of the plunger support member outwardly in response to supporting the plunger on the plunger support member to move the at least one tooth into engagement with the plurality of teeth. 18. The method of claim 14, further comprising locking the plunger with respect to the plunger support member after moving the plunger into engagement with the longitudinal edge of the electronic card. 19. The method of claim 14, wherein the step of locking the plunger with respect to the plunger support member comprises urging a plurality of teeth on one of the plunger support member and the plunger into engagement with at least one opposing tooth on the other of the plunger support member and the plunger. 20. The method of claim 14, further comprising packaging and shipping the computer chassis after moving the plunger into engagement with the longitudinal edge of the electronic card.
