Please do if the above doesn't make sense.
Okay, here is the full situation... I had a working Lombard which fell and cracked the screen. The only thing wrong is the screen, but someone with a 'dead' Pismo was willing to give it up in order that my laptop might live. I decided it would be cheaper to repair the Pismo, and needed to start tracking down the culprit. My batteries/AC and the like are all known good as they are from the Lombard. I couldn't supply a full set of symptoms because the only symptoms I got was: no sound, no power, no battery charging, no HD whirr, nothing. Kinda hard to nail something down when you have nothing to work with, isn't it? Anyways, it was actually just a logic board 'lock-up' which needed a PRAM battery disconnect and full reset. Ironic, as the guy isn't even interested in the laptop anymore. The problem now is that the sound board does still need to be replaced (sound doesn't work, although the AC does), and that the firmware on this Pismo is as it was when it left the factory back in 2000. While it is great to nail down the problem, and I could replace the board with the Lombard's (in theory), I would rather get a nice Pismo-oriented Sound/AC board. That means I have a 40GB 10.3 HD that won't boot, 10.2/10.3 CDs which twitch out when booting, and 9.0 CDs which are too old to boot to do the firmware upgrade. I do have 10.0 and 10.1 CDs which boot great and have no problems (and sees the RAM I swapped over from the Lombard, which is good). So, now I have to hunt down a 9.1 install CD so I can boot this sucker, update the firmware, and then boot back into 10.3 and move forward in college. I also need this laptop functional within the next few days, as I have obligations which are being seriously hurt (college and job) because the Lombard was my work machine away from home, and the Pismo is now tweaking because it wants new firmware, and I lack a simple install CD. I guess my main option for now, just so I can do SOME work is to grab my old 4GB drive, install 10.1 on it until I can procure the 9.1 CD. That leads me to another question... anyone here have a 9.1 Install CD they are willing to part with for a reasonable fee? ;) Regards, Adam Thayer -- G-Books is sponsored by <http://lowendmac.com/> and...
