How can i make the root device read/write?


Hi all

I'm a complete novice at this, I need to change a filename but when I boot up I get the message root device is read-only. Is there a way of changing this so that I can change the filename.

The full story is below....
I have a Mac Pro running Leopard OSX. The graphics card an NVIDIA 7500GT or driver has failed. It was suggested elsewhere that I change the relevant kext files to filename.kext.old, which I did, now when I try to boot start in OSX I get a message in various languages telling me to restart. I have tried booting in safe mode and from original Installation CD. In Safe Mode I get the same multi language splash screen, from CD I still have the graphic card problem, screen freezes and artifacts appear.

So I boot up straight into CLI by holding down CMD-S hoping to be able to change filenames back but it says device read-only.

Any help would be greatly appreciated.

I *think* the command is:

Code:
mount -o remount,r /dev/whatever
However, I've no idea what the implications of running this are, so my advice would be to wait for a more experienced forum member to respond back

Thanks Snark

I did somehow manage to stumble across a fix which did include your suggestion.

Cheers
