Boot arg for Uboot with sil0680 card ( solved )

I have just bought a sil0680card for my micro and everything goes fine except that my micro suddenly decided that my hd has not a slb on, so i have to re-copy it from the cd of amiga os final.. just one problem..

I don' t know the comand from uboot to run the system from a dvd-rom connected to the silcard..

Thanks

Edit : oppsss it was so simple..

Anyway thanks
