You need to set a jumper on the hard drive as master (I've also seen some older drives where there was a master with slave option, use that if your drive has such a setting). You also need to set your cd-rom drive's jumper to slave. Hth. Greg On Thu, Mar 07, 2002 at 06:57:07PM -0500, Alex Snow wrote: > Hi. > I am installing a temperary verson of linux on an old 486 box. To Get linux from the winblows machine to the 486, I need to install a CDrom. I hooked it to the same ribbon as the hd since there was room, but it won't boot with the cdrom on the controler. How do I tell the hd to be master and cdrom to be slave?
