hi, i am in the jungle with a last gen white macbook that started doing the 9 beep sos right after the 1.4 battery update. the updated did not seem to take (no confirmation) and on next reboot it beeps in series of 9 and never comes up. it also rejects any CD put in, including original install disc. Most posts in the web say logic board replacement, but i am about 2000km from any hope of that. Tried reseating the mem chips, and the logic board is still working enough to know when there is no mem (3 beeps). one strange thing, it's progressively gotten worse. The first time it SOSed for about 5 minutes and booted. Then, I left it SOSing overnight and by morning it booted. Now, just beeps forever. thx!!!
