Hardware / Easy check: can ArcaOS be installed on this Lenovo Laptop?
« on: December 05, 2019, 08:15:33 am »
There is a very good and easy test, wether or not ArcaOs can be installed on a Lenovo Laptop.

Till now this has to meet at least three specifications:

- Secure Boot can be turned off

- CSM is still there / Legacy boot

- USB 2.0 support

with this:

Lenovo BIOS Simulator

one can check all this before ordering hardware. That is pretty need.

My observation is, that there is no Lenovo model since the 5th Intel core-i generation, that has inbuild USB 2.0 support. That stresses the need for the USB 3.0 driver.

I attach some pictures for my next hardware test, the Lenovo Yoga 12.

During our user meeting Yesterday we had by surprise the pleasure to install an ArcaOS Alpha Version with UEFI support on the Lenovo X250 Laptop in UEFI mode!

It was a very (very!) promising Installation!

For more information please use Online Translator and look here:

Thanks to ArcaNoae for making this surprise possible!

I also do not know if to have "GUID Partition Table" support (driver) we need first the UEFI BIOS driver ready, or if it can be accomplished without that driver.
It would be interesting to finally be able to install ArcaOS in an dual boot configuration without wiping the hard drive. I know there are workarounds like cloning hard drives, etc, but it would be great to finally have the driver for a simple installation.


If GPT will work it will be interesting to know, if there is a need for a new Bootmanager or if Airboot or (guess not) the old IBM Bootmanager can handle this.

Regarding UEFI, GPT etc it would be worth to adopt more from DFSEE, if possible.

WLAN and USB are more or less to far away.

Ich hatte mal dieses Mainboard (irgendwann in den 90ern :-)  ) , auch mit SiS 900 Chipsatz. War ein sehr schönes Board!

Ich kann mich nicht mehr erinnern ob der Onboard Netzwerkchip mit OS/2 funktioniert hat oder nicht.

Jedenfalls steht auf der Homepage, unter LAN, auch ein Hinweis auf RTL8201 PHY, vielleicht hilft ja auch ein "Modernerer" oder "älterer" Realtek Treiber.

Viel Erfolg.

Some Pictures of this almost in brand new condition Laptop:

Isn't that great?

And one Picture with his elder brother, the ThinkPad 25 with OS/2 Warp 4.5 native on it  ;D

For more Information About this Laptop and ArcaOS see here:

Events / User Meeting Cologne 2019: win a Thinkpad X250!
« on: November 05, 2019, 11:39:14 am »
During this years User Meeting in Cologne on 30th of November attendents have the possibility to win a Thinkpad X250!

This is an i7-5600u Model with 8GB RAM, 256SSD, WWAN etc etc and meanwhile well supported by ArcaOS (see other Threads regarding the X250).

It is in VERY (Accus very well, and no bumps or scratches) good shape, but - for international users - it does have an DE (German) Keyboard Layout.

During the Meeting one can buy a ticket and somenone else will then pull the winner. There are 20 Tickets alltogether, each 10 Euro. The money collected will be directly transferred to BWW for the QT sponsoring.

Hardware / Re: Pen for OS/2
« on: November 03, 2019, 11:17:01 pm »
I believe Sigurd Fastenrath has posted videos of a Samsung table running with Pen for OS/2.

Just for information: I did not use PEN for OS/2 as it did not work together with the drivers I used, made by Wim Brul.
This drivers do not only work with stylus but also with touch, depending on the device you are using (i.e. Thinkpad X200 Tablet, X230 Tablet, Samsung Serie 7 Slate etc.)

I installed PEN for OS/2 to use the On Screen Keyboard Part of it, and to see if it would be usable at all. There is a Virtualkeyboard available from as well, wich is more modern.

For Writing I usually do use the JAVA 6 Program Jarnal. There are Painting Programs running with Java 6 as well.

I recently was able to get a Thinkpad 710T (from 1993 that should arrive this week) and I am going to try to install OS/2 2.1 and PEN for OS/2 on it as it should work with it. Looking forward to test it  ;)

Thanks for all the replies. I've to work it through.

I try different things in parallel - adding ArcaOS to the installed SSD while preserving the W10 installation.

I described a way for this here that points to hereür-truecrypt

Internet / Re: PMMail and EARLYMEMINIT=TRUE problem?
« on: October 09, 2019, 11:38:38 am »
If memory serves..

The only time you should not have EARLYMEMINIT=TRUE in your config.sys file is if you are using a motherboard with ISA slots, possibly that includes laptops with PCMCIA 16bit cards as well.

And if you are using HPFS386.

Hardware / Re: UNIAUD Update: Thinkpad X250 - The Perfect ArcaOS Laptop
« on: October 03, 2019, 09:58:32 pm »
Just to inform: I have been contacted by ArcaNoae and informed that it was more or less not a good idea from me that I uploaded the uniaud test file to the Forums. I already did delete it on my own after a few hours.

So I do not know when this patch will be published and if it will be "closed source" or not. I write this because some users already asked me wich X250 model would fit best (indeed I would guess it will work with any X250 ::) ) and want to inform, that the sound driver may bot ne public available. Please keep this in mind once you plan to buy an X250. For more Information you better contact ArcaNoae direct.

All the best.

The Videos will be published within my already existing Youtube Channel, so there will be no special channel. It would couse to much work otherwise.


As I wrote elsewhere: there is a patch für die UNIAUD Driver (see my report or Bugtracker 2637) so that Sound inlcuding Volume is working now with the X250 (and probaly a lot of others!).

So I will start preparing Videos this weekend!!

Thanks to the support from the ArcaOS Team with the Bugtracker!

Hardware / UNIAUD Update: Thinkpad X250 - The Perfect ArcaOS Laptop
« on: October 01, 2019, 08:31:59 am »
Thanks to Abwillis1 (Bugtracker 2637) Sound is now working on the Thinkpad X250 (and evtl. some more other models) including Volume Control!

AbWillis1 writes i.e.:

With unitest1, I see that the speaker playback volume is 0.
With unitest1:
unimix -id1 -val87 -cnt0
unimix -id1 -val87 -cnt1

These can be added to startup.cmd if they produce sound like they look like they should.

So, The Thinkpad X250 is one of the recommended ArcaOS Laptops now, as there is:

- ArcaOS can be installed from USB Stick (BIOS settings needed)
- there is still USB 2.0 support with this Laptop
- FullHD Resolution is working
- LAN is working
- about 2.9 GB of RAM is visible, RAM Disk is working
- Sound is working with this patched UNIAUD (attached)
- DOS and WINOS2 are working (without DOS window) with the VIOP Patch

-> so I can start my ArcaOS Channel using this Hardware then!

All the congrats and credits to abwillis1 and the ArcaOS Team for geiving help, advice and support via the Bugtracker!

@ Blondeguy: can you test it with the T450s as I do not have this hardware anymore?
I will test it with the Thinkpad 25 as well.

EDIT: I deleted the uni file as I do not know by now if it is allowed to chare it or if it is due to softwaresubscriptions regulations not allowed.
