Summary:  How to extract BIOS.VXD from WIN95 CAB file to solve
          error message after installing PnP BIOS.

After installing a Plug-and-Play BIOS upgrade (such as M4HS45 or M4HS45G) Windows 95 will need to make some adjustments. It may be necessary to tell Windows 95 to detect new hardware by choosing CONTROLPANEL\ADDNEWHARDWARE. This will cause WIN95 to become aware of the PnP BIOS which may cause WIN95 to need an additional file, BIOS.VXD.

WIN95 will usually ask for the installation CD-ROM or diskettes to be inserted so that it can copy this file to the hard drive. WIN95 is sometimes not able to locate the file. This may be due to a bug in WIN95 or it may be caused by using a different media or version of WIN95 than what was used to originally install WIN95.

This file BIOS.VXD is contained within a CAB (cabinet) file on the WIN95 CD-ROM or diskettes. It will be in various CAB files on various different versions of WIN95. Some of the files we have found it in are listed below. You can use a CAB file viewer to locate the correct file, if necessary, or you can just try different CAB files until the extraction works, or you can use the /A parameter as indicated below.

Here is the command to extract the file and place it in the proper directory (C:\WINDOWS\SYSTEM\VMM32):

EXTRACT /L C:\WINDOWS\SYSTEM\VMM32 D:\WIN95\WIN95_09.CAB BIOS.VXD

This would of course be adjusted according to the source and destination of this file. Above example assumes CD-ROM drive on D: and BIOS.VXD in WIN95_09.CAB and WIN95 installed to C:\WINDOWS.

On the diskette versions of WIN95, the CAB files are not in subdirectories, so the above example would be adjusted to:

EXTRACT /L C:\WINDOWS\SYSTEM\VMM32 A:\WIN95_10.CAB BIOS.VXD

Here are some of the CAB files we have found BIOS.VXD in:

Retail Upgrade CD-ROM            WIN95_09.CAB
OEM CD-ROM                       WIN95_09.CAB
Full Version on Diskette         WIN95_10.CAB  (Disk 10)
Retail Upgrade from Gateway2000  WIN95_15.CAB

EXAMPLE:

EXTRACT /A /L C:\WINDOWS\SYSTEM\VMM32 D:\WIN95\WIN95_03.CAB BIOS.VXD

This will search all CAB files starting with WIN95_03.CAB. (The CD-ROMs I looked on did not have a WIN95_01.CAB or 02 file).

Also - you may need to verify that the CD-ROM drive is being recognized by WIN95.
