EMM386 Trap Problem
This document describes a solution to the EMM386 Trap problem.
Some computers running MS-DOS EMM386, may trap and halt when PCI drivers
(or HPVGSET) are loaded. This is a known incompatibility between EMM386
and some PCI BIOS implementations. To prevent this problem, run EMM386
version 4.49 or later. Version 4.49 is shipped with MS-DOS 6.22 and is
also available on this diskette in the \EMM386 directory.
The \EMM386 directory contains the following files.

EMM386.EX#

MSUPDATE.EXE
UPDATE.BAT
To update your version of MS-DOS EMM386, do the following:
1. Create a temporary directory on the same drive on your PC as the
\DOS directory - typically the C: drive.
2. Change to the temporary directory created in the step above, and
copy the files in the \EMM386 directory on this diskette.
3. Run UPDATE.BAT to upgrade the file EMM386.SYS to version 4.49.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
