I've used InstaCake before, three different versions in fact, without problems. I have my CD drive as Primary Slave and two new 120GB as Secondary Master and Slave and I've double checked they are jumpered correctly. The BIOS shows the CD and drives are in the right places as well. Linux boots fine but when I hit return I get the /dev/ not a block device error. What am I missing here? This is using the HDR312 InstaCake I bought a year or two ago. Again, I've used this several time with no problems. Thanks.
