General Comments

Installation Procedure

Install eComStation 2.1 or ArcaOS 5.0.3 on this machine requires using an USB external mouse.

eComStation 2.1
Boot with custom setting from the CD-ROM and enable the AHCI driver. From that you can follow the installation procedure normally.
ArcaOS 5.0.3
The Boot default settings from the USB Flash drive will work to install the OS.

Issues

Trackpoint/Trackpad do not work on the Installation Procedure

No matter if you use AMouse of Single Mouse driver you will have this issue on eComStation 2.1 or ArcaOS 5.0.3.

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 (version 3.22.03).

Workaround: Have an external USB keyboard just in case.

Device Specific Comments

ACPI

The latest ACPI drivers (version 3.22.03 and 3.22.08) seems to work fine with this. It recognizes four cores on boot.

Config.sys:

PSD=ACPI.PSD /noacpi

The "/noacpi" parameter was used on ACPI.PSD for the power button to work and shut down and for the brightness buttons to work. [2]

Video

If you are using Panorama driver, it is a good idea to update to version 1.11 (from Arca Noae). 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.

Config.sys

DEVICE=X:\IBMCOM\MACS\R8169.OS2

Trackpoint/Trackpad

The trackpoint and trackpad of this device is producing an strange behaviour. 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 behaviour 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.

AMOUSE.SYS Version

I used AMOUSE.SYS from the installation.

DEVICE=X:\ECS\SYSTEM\AMouse\AMOUSE.SYS SMP

The version I currently have installed is:

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:

MOUSE.SYS Version

I changed from AMOUSE.SYS to MOUSE.SYS to see if I got a different result.

Signature:       @#IBM:10.163#@  OS/2 Mouse Device Driver
Vendor:          IBM
Revision:        10.163
File Version:    10.163
Description:     OS/2 Mouse Device Driver

MOUSE.SYS was worst. The trackpoing/Trackpad did not show any activity at all, and the USB Mouse worked to move the pointer, but clicking of the buttons stopped working.

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. But this happens a very few times, it is not very common.

Config.sys:

BASEDEV=IBMKBD.SYS

Version:

Signature:       @#D Azarewicz:10.165#@##1## 19 Jun 2013 11:35:54     DAZAR1

This driver is the patched one from David Azarewicz with the ACPI driver.

USB

The USB drivers that came with eComStation 2.1 works fine. Also the latest USB drivers. USBCALLS.DLL and USBRES.SYS was updated and it remains stable.

The config.sys looks like this:

BASEDEV=USBEHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBD.SYS
BASEDEV=USBHID.SYS
...
BASEDEV=USBMSD.ADD /REMOVABLES:8 /FLOPPIES:1
BASEDEV=USBCDROM.ADD

WebCam

The Webcam is working with USBECD drivers from Wim Brul.

By putting in the config.sys:

 DEVICE=X:\OS2\BOOT\USBECD.SYS /D:05C8:0317:#### /N:$CHICON$

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