A hardware compatibility list (HCL) is a list of computer hardware (typically including many types of peripheral devices) that is compatible with a particular operating system or device management software. The list contains both whole computer systems and specific hardware elements including motherboards, sound cards, and video cards. [1]
A compatibility layer requires the host system's CPU to be (upwardly) compatible to that of the foreign system. For example, a Microsoft Windows compatibility layer is not possible on PowerPC hardware because Windows requires an x86 CPU. In this case full emulation is needed.
The "It's now safe to power off the system" screen in Windows 10 and 11. Microsoft's Windows 98 was the first operating system to implement ACPI, [17] [18] but its implementation was somewhat buggy or incomplete, [19] [20] although some of the problems associated with it were caused by the first-generation ACPI hardware. [21]
The sound card Sound Blaster AWE32 PNP CT3990 had a Plug-and-Play ISA Bus interface chip (large square chip, mid of bottom row).. The term Legacy Plug and Play, [1] also shortened to Legacy PnP, [2] describes a series of specifications and Microsoft Windows features geared towards operating system configuration of devices, and some device IDs are assigned by UEFI Forum.

Advanced power management (APM) is a technical standard for power management developed by Intel and Microsoft and released in 1992 [1] which enables an operating system running an IBM-compatible personal computer to work with the BIOS (part of the computer's firmware) to achieve power management.
Microsoft has since dismantled this dialog box, but one way to avoid it on Windows XP was to pre-install a WHQL-certified driver before connecting the device. Since 7 January 2014, Microsoft no longer requires a WHQL testing fee, [4] which used to be US$250 per operating system family. [5] This fee covered both x86 and x64 driver SKUs, if ...
In computing, Windows on Windows (commonly referred to as WOW) [1] [2] [3] is a discontinued compatibility layer of 32-bit versions of the Windows NT family of operating systems since 1993 with the release of Windows NT 3.1, which extends NTVDM to provide limited support for running legacy 16-bit programs written for Windows 3.x or earlier.
The Microsoft Windows Driver Model unified driver models for the Windows 9x and Windows NT product lines by standardizing requirements and reducing the amount of code that needed to be written. WDM drivers will not run on operating systems earlier than Windows 98 or Windows 2000, such as Windows 95 (before the OSR2 update that sideloads the WDM ...
