I have a computer with a Syba SD-SATA2-4IR PCI SATA II 4x Internal Ports RAID Controller with SIL3124 Chipset and I just added second identical card but the second card does not seem to be recognized. The second card does not show up in device manager and the disks attached to the new card don't show up in the disk manager. Is it possible to use two of the same controller cards on a single motherboard or can I only use one at a time?
