Lenovo Thinkpad T540p (Strobopeep)


This IBM Thinkpad model is a desktop replacement, with powerful CPU and graphics and a DVD Writer. The VGA adapter is suited to an external monitor. The dock provides an easy way to take the computer with you and then later return to your desktop. The built-in screen has a screen resolution of 1920 x 1080, also known as FHD, and The IPS technology provides a display that is bright and clear.

This laptop computer is configured to boot ArcaOS. ArcaOS 5.0 has modifications specifically to support this computer. Nevertheless, Wifi and USB 3.0 are not yet supported. I have not been successful in getting any version of eComStation to run on this computer.

I have tested several T540p configurations. My ArcaOS installation DVD would not boot on a T540p that has the NVidia graphics. This Thinkpad, with Intel graphics boots the ArcaOS installation DVD with no problems. Thus, model number 20BE-004ENUS is suitable, and model number 20BE-003ENUS is not suitable. The two models are identical except for the graphics chip.

Support for an external WiFi router is installed.

Build Notes

This section documents what I did to get this computer to work under ArcaOS. It is intended to show what goes into this computer, and also as a guide to the user who wants to build it himself.

BIOS changes

The installed BIOS is 2.23 and the EC is 1.14. The current BIOS is 2.24 and EC is 1.07. I updated the BIOS to the current level with the BIOS update CD. The video displays on an external monitor without issues. I made sure that BIOS is set to Config->USB->USB 3.0 Mode = Disabled and Config->CPU->Intel (R) Hyper-Threading Technology = Disabled. Then I powered the Thinkpad down and up.

Hard drive preparation

I bought a 2 TB hard drive for Strobopeep, and installed it according to instructions in the Lenovo Hardware Maintenance Manual.

ArcaOS Installation

I installed one bootable volume, K:. The K: drive has a Custom installation that is on the minimal side.

As of ArcaOS 5.0.2, sound is working normally on the laptop. Previously, to get audio to work, I added a Trond USB audio adapter. I use Lars Erdmann's USB Audio driver and USB Wave Multimedia support. I also modified MMPM2.INI to eliminate references to Uniaud, and to use USB Audio. Audio works well, but external speakers or headphones are required.

Driver=F:\MMOS2\UNIAUD32.SYS /A:1

A fix included in ArcaOS 5.0.1 does allow DOS Full-Screen to work. Alt-Home from a DOS Full-Screen then allows a DOS Window to work.

Using Suntan Special I run sequences ArcaOS50, apps, games and cleanup. This is saved as the Factory image. This is normally what would be supplied on the computer.

The disk driver, OS2AHCI.ADD, needs to have the following parameters or else boot will sometimes fail.


External WiFi

There is not yet support for the internal WiFi. Instead, a TP-Link AC750 Wireless Travel Router is provided. Support for other external WiFi devices, the Asus RP-N12 Wireless N300 Range Extender, the TP-Link Nano Router, and the VIX Mini Travel Router is also provided.

USB Audio

For ArcaOS 5.0.2 and later, the built-in audio has OS/2 support. Earlier versions used an external USB Audio adapter provides audio support. Other than USB Audio, the standard Arca Noae stack is installed.

If a dock is included, then this is how it will work. The computer is set to the native screen of 1920 x 1080. If your monitor is the same, then nothing needs to be done docking and undocking. If the computer monitor is different than 1920 x 1080, then the screen resolution can be adjusted to the optimal values. For example, I tested with a computer monitor with a resolution of 1920 x 1200. When I plug into the dock, the computer changes to 1600 x 1200. I enter 1920 x 1200 into the screen applet and reboot for optimum resolution. When I leave the dock, the computer switches back to 1920 x 1080, and no further action is needed.


The built-in webcam can be used with WebSee software. WebSee requires iso-synchronous transfers over USB, so Arca Noae USB 11.17 is installed, rather than the newer USB 12.x because iso-synchronous transfers are not yet available in USB 12.x.


The USB 2.0 ports support keyboards, mice, scanners, thumb drives, cameras, MP3 players, external hard drives, floppies and CD Writers.

The laptop can use any memory left over from 32-bit usage as a RAM drive. For 8 GB RAM models, this RAM drive has 4.7 GB, and is formatted HPFS. For 4 GB models, the RAM drive is not configured. If activated, the RAM drive would have 700 MB.


This laptop boots to the desktop in under 60 seconds. That's important, because suspend/resume does not work. To make up for that, the laptop can do a clean power down when the lid is closed.

There is no ArcaOS support for the bluetooth or fingerprint reader. Support for the internal WiFi and USB 3.0 is under development at Arca Noae.


Suntan Special

I use Suntan Special to install the software on all Blonde Guy computers. Suntan Special software can be used to install all updates to the system and its applications and to install additional applications. When newer versions of software are released, Suntan Special can keep your Blonde Guy computer up to date.

Recovery DVD

The recovery DVD supplied is a bootable ArcaOS DVD with a backup of the hard drive as delivered. You can boot the machine from DVD, and perform maintenance functions. The maintenance folder is available on the recovery DVD. The factory backup is stored in the \Factory directory. The backups are simple zip files. You can use 7z or unzip to extract some or all of the files in a backup.


DFSee is a generic disk, partition and filesystem utility for maintenance and data-recovery. It supports partition tables (FDISK, LVM), FAT, FAT32, HPFS, NTFS, and partly JFS, EXT2/3 or REISER filesystems. DFSee is commercial software which requires a license key for continued use.

Disk Layout

The disk is partitioned to provide two bootable partitions, one for use as a server and including SAMBA server, and the other is set up for as a tradtional NetBIOS networking using the IBM File and Print client. User data is stored on a separate volume.

This is the layout for a Seagate Hybrid 2 GB hard drive.
