CS cable select doesnt always work when theres an operating system on each hard drive.... (thats why i suggest the master slave settings first )
on my dual os system i just turn of the 1st hd in the bios and it boots up XP on the second hd ... and it even reconizes the 1st hd drive for data .
but it doesnt work on CS ... (dont know why thats just how it works )
and yes some hd's have the jumpers in various locations ... some on the bottom , some on the rear or the front
