This allows it to scan the PCI configuration space to find the correct device and BARs it needs to use. To prevent this scan, and in case of two identical cards in the system, the BIOS passes the PFA (bus/device/function) to the initialization routine in AX, and the card select number (CSN) for ISA option ROMs is passed in BX.
WIA is a very significant superset of the support for digital still imaging drivers that was provided by the Still Image Architecture (STI) in Windows 98.Whereas STI only provided a low-level interface for doing basic transfers of data to and from the device (as well as the invocation of an image scan process on the Windows machine through the external device), WIA provides a framework through ...
One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...
The original secure cryptoprocessor was designed for copy protection of personal computer software (see US Patent 4,168,396, Sept 18, 1979) [5] to provide more security than dongles could then provide. See also bus encryption. Hardware cloning, where the dongle is emulated by a device driver, is also a threat to traditional dongles.
In many cases, the SAINT scanner provides links to patches or new software versions that will eliminate the detected vulnerabilities. [5] A vulnerability is a flaw in a system, device, or application that, if leveraged by an attacker, could impact the security of the system.

A hardware security module (HSM) is a physical computing device that safeguards and manages secrets (most importantly digital keys), and performs encryption and decryption functions for digital signatures, strong authentication and other cryptographic functions. [1]
A single physical PCI Express bus can be shared in a virtual environment using the SR-IOV specification. [1] [2] The SR-IOV offers different virtual functions to different virtual components (e.g. network adapter) on a physical server machine. SR-IOV uses physical and virtual functions to control or configure PCIe devices.
