leopard only boots with -f option

[drbee]

Hi My leopard installation doesn't boot unless i put the -f option at startup, otherwise it crashes loading the kernel. How can i make it boot with the -f option automatically without having to press f8 at every boot?? thanks

 

by the way...what does the -f option do??

The -f option rebuilds extensions.mkext. That file is compiled while you're in OSX and is meant to speed boot by caching all the extensions rather than loading them one by one. I've found that if I have a kernel extension that is somewhat unstable, the -f option makes it work far more consistently than it might otherwise. That said, you'd be better served in trying to track down the .kext that is causing problems and remove/fix it. When you get the kernel panic, it should have some indication on what .kext is causing the problem.

thanks. How can i do that? I looked at the system log but i can' t find anything suspicious. I think it might be something about acpi... Thanks

As a stop gap solution you can refer to this ( http://www.neonkoala.co.uk/faqs/16-booting...rwin-bootloader ) to integrate the -f boot option and other darwin boot loader options so you don't have to type it at every boot, but previous posters are right, this is most likely a rogue kext causing the kextcache problems.

thanks. It works now. I added the -f option.
