PCI-X 2.0 and PCI Express introduced an extended configuration space, up to 4096 bytes. The only standardized part of extended configuration space is the first four bytes at 0x100 which are the start of an extended capability list. Extended capabilities are very much like normal capabilities except that they can refer to any byte in the ...
Proxmox allows deployment and management of virtual machines and containers. [7] [8] It is based on a modified Debian LTS kernel. [9] Two types of virtualization are supported: container-based with LXC (starting from version 4.0 replacing OpenVZ used in version up to 3.4, included [10]), and full virtualization with KVM. [11]
Proxmox Backup Server (short Proxmox BS) is an open-source backup software project supporting virtual machines, containers, and physical hosts. [3] The Bare-metal server is based on the Debian Linux distribution, with some extended features, such as out-of-the-box ZFS support and Linux kernel 5.4 LTS. [ 4 ]

Memory-mapped I/O is preferred in IA-32 and x86-64 based architectures because the instructions that perform port-based I/O are limited to one register: EAX, AX, and AL are the only registers that data can be moved into or out of, and either a byte-sized immediate value in the instruction or a value in register DX determines which port is the source or destination port of the transfer.
Platform Environment Control Interface (PECI) is an Intel proprietary single wire serial interface that provides a communication channel between Intel processors and chipset components to external system management logic and thermal monitoring devices.
An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.
A peripheral using the PCI-SIG PCIe Address Translation Services (ATS) Page Request Interface (PRI) extension can detect and signal the need for memory manager services. For system architectures in which port I/O is a distinct address space from the memory address space, an IOMMU is not used when the CPU communicates with devices via I/O ports .
