Hard Disk is not being detected by BM OS on physical machine #46

BM OS successfully boots from the disk but the init_hdd routine does not seem to find it. The disk is connected to SATA port 0

It appears that BareMetal is not finding a PCI device with ID '0x0106' which would be a SATA controller. Debugging has been added to dump the PCI device list.

The board in question is a Asus P8H61-M LE/USB3 - http://www.asus.com/Motherboards/P8H61M_LEUSB3/ Chipset is Intel H61 - http://ark.intel.com/products/52806/Intel-BD82H61-PCH

Perhaps this is a PCI Express issue?

PCI dump did not detect any storage device on that motherboard.

Detected: 0600 Host bridge 0604 PCI bridge 0300 VGA 0780 Communication controller 0C03 USB controller 0403 Audio device 0604 PCI bridge 0C03 USB controller 0601 ISA bridge 0C03 USB controller 0604 PCI bridge 0200 Ethernet

Not searching PCI properly? Change needed for PCI Express?

Functions were not being tested for (Some PCI devices have multiple functions). Fixed!
