Instalation Procedure

Install eComStation 2.1 on this machine using a USB external mouse.

Boot with custom setting from the CD-ROM and enable the AHCI driver. From that you can follow the installation procedure normally.


Trackpoint/Trackpad do not work on the Installation Procedure

Workaround: Use external USB mouse. Issue: [1]

Keyboard stops working

Sometimes the keyboard of the thinkpad stops working. This seems to be because of the other ACPI driver.

Workaround: Have an external USB keyboard just in case.


If you are using Panorama driver, it is a good idea to update to version 1.03 (from Mensys beta downloads). It will allow you to select the 1366x768 video resolution.

Wired Network

The RealTek Semiconductor RTL8168D/8111D PCI-E Gigabit Ethernet Adapter for recognized with the R8110.OS2 network driver when it installed. But it did not work, it loads but it not works to connect to the network. So I used Multimac R8169.OS2 and it started to work.


The trackpoint and trackpad of this device is producing an strange behavior. At first it did not work at all during the installation procedure, so an external USB mouse was required.

After updating ACPI to version to version 3.22.03, it starts working but sometimes it gives an strange behavior and ever movement of the mouse or mouse click (both trackpoint and trackpad) opens the "Windows List". The final word is that sometimes it works and sometimes not.


Signature:       @#NB:2.75.00#@ Driver for Scroll Mouse (c) 2006
Vendor:          NB
Revision:        2.75.00
File Version:    2.75
Description:     Driver for Scroll Mouse (c) 2006

I also get this message from time to time which is very odd because the trackpoint do not have battery:



The Thinkpad keyboard also shows some strange behaviour. Sometimes it works, sometimes it loose connection. The only workaround is to have an USB keyboard around just in case.

When the Thinkpad Keyboard stops working, you connect an USB keyboard and both starts working, after that you can disconnect the USB keyboard.


The USB drivers that cames on eComStation 2.1 works fine. Also the latests Lar's USB drivers and the USB drivers patched by ACPI. USBCALLS.DLL and USBRES.SYS was updated and it remains stable.


The Webcam is working with USBECD drivers from Wim Brul.

By putting in the config.sys:


The device got recognized and named as "CHICON". After that you can use the W520TC exe files to take some snapshots.
