The kernel I installed is:

2.6.12-1.1398_FC4

But the name of the downloaded file is called:

kernel-2.6.12-1.1398_FC4.stk16.i686.rpm.zip

The kernel is listed and can be downloaded from:

http://www.linuxant.com/driverloader/wlan/full/downloads-fc4-kernel- 
i686.php

And, before I get the kernel panic, the screen reads:

"Booting Fedora Core (2.6.12-1.1398_FC4.stk16)"

I noticed in my previous email that I wrote "2.6...388" .. should  
have said "2.6...398".

Do you think that I used the incorrect kernel and that this caused  
the kernel pacic. I have since tried another install, with the same  
result.

By the way, I read somewhere that the mimo-based or pre-n cards might  
not be supported by ndiswrapper. I wonder if this is the case with  
Linuxant?


Thanks,
Paul
