SYMPTOMS
========

When you start your computer from a network boot disk with no special settings
for Emm386.exe and then run Windows 95 Setup from a network drive, Setup may not
finish correctly. When this occurs, you may find that the file allocation table
(FAT) on drive C is damaged when you restart your computer with a startup floppy
disk.

CAUSE
=====

The damage occurs because the network boot disk loads Emm386.exe without any
exclude ranges for the network card and Windows 95 Setup starts Smartdrv.exe.
When SmartDrive puts its buffer into the high memory area (HMA), it overlaps the
memory area the network card is using. During the file copy process, this data
is damaged and gets written to the hard disk.

RESOLUTION
==========

To avoid this problem, use one of the following methods:

- Use the correct exclude range for the installed network card.

- Start Setup with the following command to avoid starting SmartDrive:

  setup /c

- Do not use Emm386.exe or any other memory manager.
