AMD EnTier Virtualized AHCI Controller Driver
When you create a virtual machine, the default controller is I currently dual boot Win XP Pro (with slipstreamed AHCI driver) and Win 7 on a gb ssd. . the only tutorials I've found were about passing through entire PCIe. The entire SATA controller and the virtual disks attached to it, including those in IDE compatibility mode, will not be seen by OSes that do not have device. The Z9PE-D16 boasts multiple SAS implementation, from Intel® SCU/AHCI to This ensures high power efficiency for the entire system to help customers save and control, virtual media over LAN, and management LAN fail-over support.

AMD EnTier Virtualized AHCI Controller Driver
But the problem is it still does not see the 4TB drives installed in the machine.
No AHCI driver exists for VEN_ DEV_43B7 Community
This is where I am stuck. Thank you in advance for reading my post and for any assistance you can offer. As opposed to SCSI, however, with physical devices, serial cables are used instead of parallel ones, which simplifies physical device connections.
At this time, up to eight devices can be connected to the SAS controller. The USB mass storage device class is a standard to connect external storage devices like hard disks or flash drives to a host through USB.

All major OSes support these devices for a long time and ship generic drivers making third-party drivers superfluous. While AMD EnTier Virtualized AHCI Controller storage controllers appear as a single PCI device to the guest with multiple disks attached to it, the USB-based storage controller does not appear as virtual storage controller. Each disk attached to the controller appears as a dedicated USB device to the guest. OSes need to support NVMe devices to make use of them. For example, Windows 8.
If AMD EnTier Virtualized AHCI Controller take a snapshot of a machine with immutable images, then on every machine power-up, those images are reset to the state of the last current snapshot, instead of the state of the original immutable image. Note As a special exception, immutable images are not reset if they are attached to a machine in a saved state or whose last snapshot was taken while the machine was running. This is called an online snapshot.
As a result, if the machine's current snapshot is an online snapshot, its immutable AMD EnTier Virtualized AHCI Controller behave exactly like the a normal image. To reenable the automatic resetting of such images, delete the current snapshot of the machine. Oracle VM VirtualBox never writes to an immutable image directly at all. All write operations from the machine are directed to a differencing image.
Chapter 5. Virtual Storage
The next time the VM is AMD EnTier Virtualized AHCI Controller on, the differencing image is reset so that every time the VM starts, its immutable images have exactly the same content. The differencing image is only reset when the machine is powered on from within Oracle VM VirtualBox, not when you reboot by requesting a reboot from within the machine.
This is also why immutable images behave as described above when snapshots are also present, which use differencing images as well. If the automatic discarding of AMD EnTier Virtualized AHCI Controller differencing image on VM startup does not fit your needs, you can turn it off using the autoreset parameter of VBoxManage modifyhd. Multiattach mode images can be attached to more than one virtual machine at the same time, even if these machines are AMD EnTier Virtualized AHCI Controller simultaneously. For each virtual machine to which such an image is attached, a differencing image is created. As a result, data that is written to such a virtual disk by one machine is not seen by the other machines to which the image is attached.
Each machine creates its own write history of the multiattach image. Technically, a multiattach image behaves identically to an immutable image except the differencing image is not reset every time the machine starts.

This mode is useful for sharing files which are almost never written, for instance picture galleries, where every guest changes only a small amount of data and AMD EnTier Virtualized AHCI Controller majority of the disk content remains unchanged. The modified blocks are stored in differencing images which remain relatively small and the shared content is stored only once at the host.
The following scenario illustrates the differences between the various image modes, with respect to snapshots. Assume you have installed your guest OS in your VM, and you have taken a snapshot.
Later, your VM is infected with a virus and you would like to go back to the snapshot. With a normal hard disk image, you simply restore the snapshot, and the earlier state of your hard disk image will be restored as well and your virus infection will be undone. With an immutable hard disk, all it takes is to shut down and AMD EnTier Virtualized AHCI Controller on your VM, and the virus infection will be discarded.
Innovative technologies deliver easy expandability, complete storage and high power efficiency
With a write-through AMD EnTier Virtualized AHCI Controller however, you cannot easily undo the virus infection by means of virtualization, but will have to disinfect your virtual machine like a real computer. You might find write-through images useful if you want to preserve critical data irrespective of snapshots. As you can attach more than one image to a VM, you may want to have one immutable image for the OS and one write-through image for your data files. Differencing Images The previous section mentioned differencing images and how they are used with snapshots, immutable images, and multiple disk attachments.
