Hi! Yes, CS stands for cable select. Originally used by old drives, where the cabling told them who was master and slave, this jumper exists on modern drives only due to some "compatibility" reasons, until ATA/66 came up. In normal mode, you _had_ to set the CS jumper to disabled and set via MAster/Slave jumper the right combo. The ATA/66 cabling has also CS feature (Principally like with the FDD cabling, with some pin assignment)built in, so the cable will tell the drives again what they are. If you use a 40-pin standard cabling with them, or mix something (like CDROMs, that often cannot do even DMA modi), it will a) mess up certain things, as it still is cheapo IDE, and therefore not designed nor intended to run really well, and b) you will have to tell them again manually what to do via jumpers/BIOS settings. Problems are also caused in wide areas with unstable or too early Mainboard BIOSes.
