SATA Hard Drive does NOT show up in Device Manager
I am trying bring-up a new SATA Hard Drive through PCIe to SATA AHCI Host Card. We find that Vista recognized the AHCI Controller and it shows up in the Device Manager. It successfully allocates the memory and IRQ, and says that the Device is working properly. But the HDD is not recognized. When we look at the PCIe analyser, we see that the OS is continuously polling the AHCI Interrupt Status Register (Addr: 0x08). This register is reading 0x0 all the time. Any help on this is appreciated. Is there any way to find out the flow to find a device. |
