How to turn off DMA turing install

Sat Dec 11 10:38:38 UTC 2004

Hi,
My laptop has been fixed by the factory and they replaced the motherboard. Now 
Fedora or any old Redhat will not install anymore (error 2 cpio no magic) I 
have a clue that the source of my problems is DMA of the cd-rom and I want to 
try turning it off during the install. 
What arguments should I pass on the command-line to turn it off?

I have searched google, the archives and everything else I could think off, 
but that did not do the trick.

Thanks,
