The Management Engine is often confused with Intel AMT (Intel Active Management Technology). AMT runs on the ME, but is only available on processors with vPro.AMT gives device owners remote administration of their computer, [5] such as powering it on or off, and reinstalling the operating system.
Version 1 of the Desktop Management BIOS (DMIBIOS) specification was produced by Phoenix Technologies in or before 1996. [5] [6] Version 2.0 of the Desktop Management BIOS specification was released on March 6, 1996 by American Megatrends (AMI), Award Software, Dell, Intel, Phoenix Technologies, and SystemSoft Corporation. It introduced 16-bit ...
At least one Asus board [which?] is known to have faulty BIOSes with corrupt ACPI IVRS tables; for such cases, under Linux, it is possible to specify custom mappings to override the faulty and/or missing BIOS-provided ones through the use of the ivrs_ioapic and ivrs_hpet kernel parameters.
UEFI replaces the BIOS that was present in the boot ROM of all personal computers that are IBM PC compatible, [5] [6] although it can provide backwards compatibility with the BIOS using CSM booting. Unlike its predecessor, BIOS, which is a de facto standard originally created by IBM as proprietary software, UEFI is an open standard maintained ...
DMI 1.0, introduced in 2004 with a data transfer rate of 1 GB/s with a ×4 link.. DMI 2.0, introduced in 2011, doubles the data transfer rate to 2 GB/s with a ×4 link.It is used to link an Intel CPU with the Intel Platform Controller Hub (PCH), which supersedes the historic implementation of a separate northbridge and southbridge.
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
VT-d is broken or non existent on some boards until the BIOS is updated. Note that VT-d is a chipset Memory Controller Hub technology, not a processor feature, but this is complicated by later processor generations (Core i3/i5/i7) moving the MCH from the motherboard to the processor package, making only certain I series CPUs support VT-d.
