Device drivers in Windows 9x can be virtual device drivers or (starting with Windows 98) WDM drivers. VxDs usually have the filename extension.vxd or .386, whereas WDM compatible drivers usually use the extension .sys. The 32-bit VxD message server (msgsrv32) is a program that is able to load virtual device drivers (VxDs) at startup and then ...
Although Windows 98 introduced the Windows Driver Model (WDM), VxD device drivers can be used under Windows 98 and Windows Me. Using VxD drivers instead of WDM drivers in Windows 9x may result in advanced ACPI states like hibernation being unavailable. VxDs are not usable in Windows NT or its descendants.
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 ...
The Windows 9x kernel is a 32-bit kernel with virtual memory. Drivers are provided by .VXD files or, since Windows 98, the newer WDM drivers can be used. [2] However, the MS-DOS kernel stays resident in memory. Windows will use the old MS-DOS 16-bit drivers if they are installed, except on Windows Me. In Windows Me, DOS is still running, but ...

The kernel is stored in MSDOS.SYS with MS-DOS and in IO.SYS with Windows 9x. At this point, "normal" file access is available. Processes the MSDOS.SYS file with Windows 9x. Processes the CONFIG.SYS file, in MS-DOS 2.0 and higher and Windows 9x. Loads COMMAND.COM (or other operating system shell if specified). Displays the bootsplash in Windows 9x
However, Windows 3.1 had two separate successors, splitting the Windows line in two: the consumer-focused "Windows 9x" line, consisting of Windows 95, Windows 98, and Windows Me; and the professional Windows NT line, comprising Windows NT 3.1, Windows NT 3.5, Windows NT 3.51, Windows NT 4.0, and Windows 2000.
On Windows 9x and Windows NT, the ASPI manager is generic and relies on the services of SCSI miniport drivers. On those systems, the ASPI interface is designed for applications which require SCSI pass-through functionality (such as CD-ROM burning software). [1]: 57
