VFAT Device Initialization Failed.

不存在下面解释中的问题：
VFAT INITIALIZATION ERROR

When starting Windows 95 or 98, you receive the following:

VFAT Device Initialization Failed.

A device or resource required by VFAT is not present or is unavailable.

VFAT cannot continue loading.

System halted.

More than likely, the problem involves the Ifshlp.sys file. It's
possible that:

* The file is missing from the Windows folder.

* There's a line in the Config.sys folder that points to an old version
of the file. (Check for multiple copies of Ifshlp.* on your hard
drive.)

* The device= line in Config.sys that references Ifshlp.sys has been
REM'd out or deleted.

* The entries in the [Paths] section in MSDos.sys are incorrect--they
don't point to your current Windows installation.

* There's a Winboot.ini file from an incomplete installation of Windows
in the root of the boot disk.

Identify which of these situations is causing the problem, and you're
well on your way to solving it. Clearly, one cause of this problem is
the reinstallation, or attempted reinstallation, of Windows.

各位朋友如何解决？
