Load Failures Listed in the Bootlog.txt File

This article was previously published under Q127970
The Bootlog.txt file in the root folder on your hard diskmay contain the following lines, even though your computer is running properly:
  • LoadFailed = dsound.vxd
  • LoadFailed = ebios
  • LoadFailed = ndis2sup.vxd
  • LoadFailed = vpowerd
  • LoadFailed = vserver.vxd
  • LoadFailed = vshare
  • InitCompleteFailed = SDVXD
NOTE: The Bootlog.txtfile on a computer that is running Windows 98 may also contain the following lines:
  • Deviceinitfailed = MTRR
  • SysCritInitFailed = JAVASUP
  • DeviceInitFailed = MTRR
These load failures do not necessarily indicate a problem. It iscommon for some, if not all, of these load attempts to fail, depending on your systemconfiguration. The following sections of this article contain more information about the causes of specific types of load failures.

LoadFailed = dsound

Many sound drivers are DirectSound-enabled. DirectSound is part ofMicrosoft DirectX, a set of libraries that are used by most Windows-basedgames. When a DirectSound-enabled sound driver is loaded, the driver attempts toregister with the DirectSound library so that games can use the library. If noDirectX-based games are installed on your computer, the DirectSoundlibrary is not loaded. This behavior is typical.

LoadFailed = ebios

If the extended basic input/output system (BIOS) driver does not find an extended BIOS, the driver is not loaded.

LoadFailed = ndis2sup.vxd

If the network driver interface specification (NDIS) 2 support driver does not find any NDIS 2 drivers to support,the driver is not loaded.

LoadFailed = vpowerd

If the Advanced Power Management (APM) driver determines that your computerdoes not support APM, the driver is not loaded. However, APM support might be disabled. To determine if APM is disabled in Device Manager:
  1. Click Start, point to Settings, and then click Control Panel.
  2. Double-click System, and then click the Device Manager tab.
  3. Double-click to expand System Devices.
  4. Double-click Advanced Power Management Support to open its properties. (If Advanced Power Management Support is not listed, your computer does not support APM.)
  5. Click the Settings tab.
  6. Verify that the Enable Power Management Support check box is selected.

LoadFailed = vserver.vxd

Vserver.vxd saves memory by loadinglater in the startup process only if it is needed, rather than loading statically. For example, Vserver.vxdmight not be needed when you start a laptop computer while the laptop computer is out ofits docking station.

LoadFailed = vshare

If you examine the Bootlog.txt file, the file indicates that Vshare loadedsuccessfully earlier in the startup process. The second copy of Vsharedetects the instance of Vshare that is already loaded, and the second copy is not loaded.

Font Failures

After you first start Windows, the Bootlog.txt file may list manyfont load failures. This behavior is typical. When Font Managersearches the hard disk for fonts, it may find fonts in several folders.After Font Manager finds fonts, it records the information so that future attemptsto locate a font proceed more quickly.

InitCompleteFailed = SDVXD

Windows automatically loads a miniature disk cache to increase thespeed of the startup process. When the startup process is complete, theminiature disk cache is unloaded from memory. When the cache is unloaded, the"InitCompleteFailed = SDVXD" line is added to the Bootlog.txt file to indicate that the miniaturedisk cache has been removed from memory. This behavior is typical.

SysCritInitFailed = JAVASUP

If the Java support driver is not needed on your computer, the driver is notloaded. Java is a programming language that is used on the World Wide Web (WWW).Microsoft Internet Explorer versions 3.0 and later include a Javasubsystem.

DeviceInitFailed = MTRR

Memory Type Range Registers (MTRR) is a .vxd file that is responsible formanipulating memory ranges. This file is loaded with DirectX 5.0;however, none of the DirectX core components use the service that is providedby MTRR. The Ntkern file and some video adapter drivers do use the service that is provided by MTRR to change memory ranges.
