I'm not loading any drivers in my new kernel, I'm just doing pure BIOS disk I/O using Int13 calls (the program I start using kexec I would not actually call a 'kernel', it's just a very tiny piece of software which does some disk I/O and output on the screen). Attached you find the output of lspci -v Best regards Christian --------------060901050902040703040606 Content-Type: text/plain; name="lspic_d520.txt" Content-Transfer-Encoding: 7bit
