SATA AHCI controller detection during PCI enumeration

SATA AHCI controller detection during PCI enumeration

[Murali Karicheri]

All,

I have a board with PCI controller connected to a Marvell AHCI 
controller, 88SE9182 connected to a PCIe bus and the PCI scan doesn't 
show up the SATA end point. My question is in order to detect the EP,
is it expected to have a hard drive connected to the SATA port?
Currently with and without the SATA connected, the PCI scan doesn't
show up the device. Also is there any other requirements at the
hardware level to detect this SATA controller.

Thanks in advance for your reply.

No

Does this PCIe2SATA card work with standard PC?

I do not know about this Marvell controller, but I remember one
silicon image controller which worked with only Gen1 host port.
You may ask card vendor if there is any such limitation.

Pratyush,

Thanks for the reply. I will touch base with the Vendor on this.
