Lenovo Thinkpad T540p (Strobopeep)
The Lenovo Thinkpad T540p is a replacement for a desktop computer. It has a with powerful CPU, graphics and a DVD Writer. The keyboard is large enough to have a numeric keypad. 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.
These are some useful additions you can buy to customize this computer. If more customizations are needed see the section named Custom orders below.
There is not yet support for the internal WiFi. I use the VIX Mini Travel Router with this laptop to access local WiFi or my phone's hot spot. VIX Mini comes with everything you need to connect to an access point.

In the past, I have also used a TP-Link AC750 Wireless Travel Router, an Asus RP-N12 Wireless N300 Range Extender, and a TP-Link Nano Router. I include a folder of URL links to the admin pages of each of these routers to make it easy to set up the first time.

Strobopeep is compatible with Thinkpad Ultrabase Dock 40A1 and 40A2. ArcaOS cannot dock/undock a running computer. You must shutdown the computer when docking and undocking. The 40A1 dock has 6 USB ports, VGA, DVI, audio and Ethernet.

If a dock is included, here's how it works: 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.
Hard drive upgrade
The hard drive can be upgraded to a 2 TB drive. Either a hard disk or an SSD is available to upgrade.

Power consumption is 16 Watts, measured with the computer booted to the desktop. This computer consumes less than 1 Watt if it's plugged in, but switched off. When charging a depleted battery, it consumes up to 45 Watts.
The built-in webcam can be used with WebSee software. WebSee requires iso-synchronous transfers over USB, so Arca Noae USB 11.17 is needed, rather than the newer USB 12.x because iso-synchronous transfers are not yet available in USB 12.x.
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.
The USB 3.0 support support for Mass Storage is not curently working. With the USB 3.0 Enabled setting in BIOS enabled, mouse and keyboard is not reliable while docked and not at all without the dock.
USB driver version 11.17 works well, including mass storage, mouse, keyboard. USB 2.0 support is unreliable while docked.
There is no ArcaOS support for the bluetooth or fingerprint reader. Support for the internal WiFi is under development at Arca Noae.
The disk is partitioned to provide a bootable operating system volume and a bootable installer. Space is left for addtional bootable volumes. User data is stored on a separate volume.
This is the layout for the 500 GB HD. The Air-Boot boot manager is installed to select the volume to be started.

ArcaOS 5.0.5 (Jun 6, 2020) is the version used for this installation.

- Computer maintenance programs include Suntan Special, a trial version of DFSee, Sysbench to measure the speed of the computer, PCI to scan the system hardware and SystemInfo to view the entire computer configuration.
- RPM/YUM, a software configuration framework, is installed. Suntan Special acts as a layer over RPM/YUM to replace the detailed knowledge of how to install and configure software using YUM with pre-packaged application installations.
- The FAT32 file system is installed.
- Firefox and Seamonkey web browsers are installed. For the Mozilla family browsers, the Flash plugin is installed, but off by default. Qupzilla web browser, based on Qt and the Apple Web Kit is also installed.

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.
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.
This laptop computer is configured to boot ArcaOS. ArcaOS 5.0 has modifications specifically to support this computer. Nevertheless, Wifi is 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.
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.
I made sure the BIOS was updated to the latest version. This may not be necessary, but I did it anyway. The installed BIOS was 2.23 and the EC is 1.14. The current BIOS is 2.37 and EC is 1.15 released on 2019/09/17. I updated the BIOS to the current level with the BIOS update CD downloaded from the Lenovo support website.
I made the following changes to the default BIOS settings. Then I powered the Thinkpad down and up.
- Config->USB->USB 3.0 Mode = Enabled (unless USB 11.17 is used for WebCam)
- Config->Keyboard/Mouse->Trackpad = Disabled (I don't like trackpad)
- Config->Display->Boot Display Device = Analog VGA (The video displays on an external monitor without issues.)
- and Config->CPU->Intel (R) Hyper-Threading Technology = Disabled. (ArcaOS kernel issue left over from OS/2)
- Startup->UEFI/Legacy Boot = Both (need both to boot BIOS update, otherwise Legacy Only is fine.)
- Startup->UEFI/Legacy Boot - UEFI/Legacy Boot Priority = Legacy First
- Startup->UEFI/Legacy Boot - CSM Support = Yes
Hard drive preparation
I bought a 2 TB hard drive for Strobopeep, and installed it according to instructions in the Lenovo Hardware Maintenance Manual. The drive can be prepared using the ArcaOS installer or with DFSee. This is how I prepared the drive with DFSee.
- install new SSHD to Strobopeep
- Using DFSee, change geometry to 127-255
- Wipe the hard drive (first 0.5 percent is sufficient)
- boot ArcaOS 5.0 CD and use diskutil to make new MBR
- boot ArcaOS 5.0 CD and install ArcaOS from response file
- configure Samba client to autoconnect to the Blonde Guy server
- install Suntan Special and run strobopeep.seq
- create recovery DVD
I installed one bootable volume, Q:. The Q: drive has a Custom installation that includes some developer tools. I made a recovery partition on volume X:. A System Dump partition is now included.
As of ArcaOS 5.0.5, sound is working normally on the laptop. Both UniAud and USB audio are installed and working. ArcaOS now switches between UniAud and USB audio automatically when a USB audio device is attached. The UniAud driver should be configured as follows to make sound.
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.
BASEDEV=OS2AHCI.ADD /N /F /V:2
