I just set up an athlon system for a friend and his motherboard(iwill kk266) only came with one ide cable. We reused an ide cable from his old system to set up the second channel. I dont know what transfer speeds his hard drives and cdrom drives are capable of but I would like to make sure the system is ata100 ready. The cable was from a p3 450 system, so its not ancient... but is there any way to tell whether or not it can handle ata100? Can all recently made cables do it? TIA
