Yes, the chipset is capable of supporting independent IDE device timings. Although, if the hard drives are mixed they may run at the slowest Ultra DMA protocol depending on whether you are using the native operating system IDE driver or Intel® Application Accelerator. Intel® Application Accelerator allows each device to run at its optimal timings. Check with your OS provider to see if their native IDE driver supports independent timings for IDE devices. It is recommended that the Ultra ATA/100 drives be attached to the primary IDE channel using a 40-pin 80-conductor IDE cable and that the other drives be attached to the secondary channel using a good quality, 40-pin 40-conductor IDE cable.
