On 19 May 2020, however, AMD changed its position and stated that Zen 3 would be coming to selected older X470 and B450 motherboards via a BIOS update. [45] This would be achieved by disabling support for some older AM4 processors in the BIOS ROM in order to allocate space to support the newer processors.
The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2]
AMIBIOS is the IBM PC-compatible BIOS that was formerly developed and sold by American Megatrends since 1986. [10] In 1994, the company claimed that 75% of PC clones used AMIBIOS. [16] It is used on motherboards made by AMI and by other companies. [3] A chip containing an old version AMIBIOS image, pulled from an ECS motherboard

In computing, BIOS (/ ˈ b aɪ ɒ s,-oʊ s /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).

ROM BIOS firmware on a Baby AT motherboard. In some respects, the various firmware components are as important as the operating system in a working computer. However, unlike most modern operating systems, firmware rarely has a well-evolved automatic mechanism of updating itself to fix any functionality issues detected after shipping the unit.
When enabled via the AHCI controller, this allows the SATA host bus adapter to enter a low-power state during periods of inactivity, thus saving energy. The drawback to this is increased periodic latency as the drive must be re-activated and brought back on-line before it can be used, and this will often appear as a delay to the end-user.
