Super IO CHIP's Serial High Speed mode Support for Windows 2000 Universal V2.1

INTRODUCTION

We developed the tool to support SMC, Winbond, NS, and ALi chipsets with Serial High Speed mode for Windows 2000.
It has been inspected on our environment, but we don't guarantee this package you wish to download will work with your environment. Please use this at your own risk. This tool will rewrite system files, so you should have a special notice for installation. Good luck!

This is a second version for Windows 2000 which has a NT4.0 version based function. The utility "SHSMode.exe" is a new version since this release. As the knowledge of this tool history, we packed NT4.0 document inside. We strongly recommend to read this document before installation.

Please give us some more time to release next version, which should support VIA chipsets.
ITE doesn't support high speed mode.

IMPORTANT NOTICE: For Winbond and NS users only (A serial mouse does't work!)

Since you install this driver, the system should support only high speed mode. In the system inside, serial ports always work 8 times speed than before. So the serial mouse and low speed serial device should not work on this environment. Before installation, please inspect not to use these serial mouse and low speed devices.

IMPORTANT NOTICE: DEVICE DRIVER REPLACEMENT

This package will make replace Windows 2000 system file "SERIAL.SYS" at "\winnt\system32\drivers" directory. Windows 2000 has a new feature as "Windows File Protection" which prohibits modification of its System File. It is needed for installation to execute a patching command on special environment as below. It should make replace a system file against OS vender policy. Please give up to install if you don't have enough skill about this explanation. If you attempt any file action for "SERIAL.SYS" on Windows 2000 normal mode, Windows 2000 original "SERIAL.SYS" should be rewritten back again soon.

Store a downloaded file and unzip into temporally directory.
Input the command "SFC /CANCEL" on Windows 2000 command prompt to stop System File Checker at boot time.
Reboot the system with Safe Mode.
Double click instshs.bat at unzipped directory. Executing this batch will update the Windows 2000 serial port driver serial.sys. The original version will be saved with the filename $erial.sys in case you want to restore it.
If it says something like:
.
Error - Check security. etc.

Then, most likely, Something funny, or you are not running the illegal version of Windows.
If so, try again after reinstalling the correct version of serial.sys.

If it says something like:
1 file(s) copied.
1 file(s) copied.
Successful.

It means the serial driver has been successfully updated.
Reboot the system with Normal Mode.
