 **Note:**
  The HCL is a compilation of reports generated and submitted by users. Except in the case of developer-reported entries, the Qubes team has not independently verified the accuracy of these reports.

+ If using the list to make a purchasing decision, we recommend that you first consult the datasheets (CPU, chipset, motherboard) for particular support of:

+-   HVM ("AMD virtualization (AMD-V)", "Intel virtualization (VT-x)", "VIA virtualization (VIA VT)")
+-   IOMMU ("AMD I/O Virtualization Technology (AMD-Vi)", "Intel Virtualization Technology for Directed I/O (VT-d)")
+-   TPM ("Trusted Plaform Module (TPM)" connected to a "20-pin TPM header" on motherboards.)

  Try to shop for hardware with best achievable Qubes security level (green columns in HVM, IOMMU, TPM) and general machine compatibility (green columns in Qubes version, dom0 kernel, remarks).
