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.
Issues
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.
Video
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.
Trackpoint/Trackpad
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.
Keyboard
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.
USB
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.
