[Wirelessdriver-support] Removing files from terminal

[John L. <joh...@ea...>]

Okay. I give up. I have tried repeatedly to remove the 
Extensions.kextcache and Extensions.mkext files from /System/Library -- 
with no success. I get to the terminal application fine by restarting 
with Command and S depressed, and I get down to the last line that says 
"sh-2.05a#: ". When I try to run the sudo rm -r (filename) command from 
that point, I'm told that the file is read-only. But just above that is 
a string of lines:

Singleuser boot -- fsck not done
Root device is mounted read-only
If you want to make modifications to files, run '/sbin/fsck -y' first 
and then 'sbin/mount -uw/'

I do that (seemingly successfully), and then run the sudo rm -r on the 
two files. Each time, I get no confirmation that the files have been 
removed, just the "sh-2.05a#:" at the beginning of the next line. After 
I reboot, and do a Find on these files, I find that neither has been 
removed. They are both still in /System/Library.

One other possible problem is that above the "Singleuser boot" string 
is a line (just under the "IODeviceTree" line, that says:

ATA Disk: Identify data is incorrect - bad checksum

What's happening? What am I doing wrong?

I'm obviously no programmer, but I didn't think I had to be.

Any advice from anyone on this would be appreciated.

Thanks.
