Hi Chris, On Jan 18, 2004, at 4:58 PM, Chris Walters wrote: I am not sure why the debug driver does not load. You can verify it with the following command after installing it. Be certain that the source it built on the appropriate system version as well. kextload -nt /System/Library/Extensions/IOStorageFamily.kext I ran this and it said the kext appears to be valid. If I reboot with the partition as the default startup system it displays an apple with a black line above it (appearing like it is displaying text, maybe the reason why it fails, but the box isn't big enough). If I boot with the partition not as default then a "no entry" sign appears. This usually means that you've tried to run with an unstripped version of a kernel extension. All of the symbols in your KEXT have most likely chewed up all of the kernel's memory map. On Panther, the kernel's map was expanded quite a bit, so this limit is harder to reach. But you should always strip KEXTs you plan to load, especially shipping ones. Note that if you're doing two-machine debugging, the symbols go on the debugging system, not the target system. And if you've just embedded extra IOLogs or the like, stripping won't affect that functionality.
