I don't have an answer to that; but, why do you care?<br />

 &nbsp;This might be silly. Just provide for some reference. :)<br />

&nbsp; Enumerate all keys under HKLM\System\CurrentControl<wbr />Set\Servic<wbr />es\Class\S<wbr />ystem<br />
<br />
Check value &quot;InfSection&quot; and &quot;DevLoader&quot; under all these keys. If InfSection = &quot;ISA_DRV&quot; and DevLoader = &quot;isapnp.vxd&quot;, the machine has ISA bus. If InfSection = &quot;PCI_DRV&quot; and DevLoader = &quot;pci.vxd&quot;, the machine has PCI bus. I am not sure about EISA and VESA.<br />
<br />
&nbsp;The DevLoader might be changed and I am also not sure whether it is reliable to check only value &quot;InfSection&quot;. &nbsp; <br />
<br />
&nbsp;Hope this help. <br />

Check value "InfSection" and "DevLoader" under all these keys. If InfSection = "ISA_DRV" and DevLoader = "isapnp.vxd", the machine has ISA bus. If InfSection = "PCI_DRV" and DevLoader = "pci.vxd", the machine has PCI bus. I am not sure about EISA and VESA.

 The DevLoader might be changed and I am also not sure whether it is reliable to check only value "InfSection".  

 Hope this help.

Bus Type

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
