My new Dell OptiPlex GX300 (running 4.1-RELEASE) came with an 80-wire ATA cable. I added a second drive and am using this cable for both drives. However, the kernel fails to recognize the cable and is limit- ing DMA speed accordingly. Any ideas? See below for the relevant portion of the "boot -v" output. I note the "cblid=0" value -- leading me to wonder if the problem might possibly be with the integrated ATA controller on the motherboard not sensing or reporting the cable properly. This is an 800-MHz Pentium III system, though, so I find it a bit hard to believe that it isn't UDMA66-capable. BTW, in the line which claims I have a non-ATA66 compliant cable, I believe the preferred spelling is "limited", with just one T (not two).
