Now that I've brought my PowerBook from the dead, I am trying to get 8.6 onto the machine to test and use the Dell TrueMobile 1150 wireless card I bought for it. I tried installing 8.6 on the 2400, rebooted, and it tells me that "this startup disk cannot be used with this computer". The drive was formatted with 8.1 then I let the 8.6 installer update the driver. I thought that maybe my 8.6 CD was new world specific (iMac and newer), so I grabbed my 8.5 CD, installed, and am being confronted with the same error message. I haven't tried 9 yet, but I'm getting there. 8.1 works fine on the machine, and is probably what will end up on it as my final goal is to put Linux on the PowerBook, but I need to test the wireless card before I tackle making PCMCIA work in Linux. I have pretty much every system from 0.6 up to 10.3, so I can try almost any combination of installations and updates. I'm stumped, and any suggestions would be welcome. I have the original 1.3GB drive installed, 48MB of RAM, and a stock 180Mhz processor. The only mods done to it are the cardbus wire cutting (which works), replacing a 2A fuse, and replacing the wires on the bottom of the motherboard with new ones. As an aside, does anyone have any experience with the NewerRAM/Edge branded 64MB RAM module for the 2400c? Mine isn't being recognized at all (brand new), and I was wondering if I should bother getting it replaced, or just return it for a refund. -- Chuck Kenney FreeFall Software http://www.freefallsoftware.com/
