Mango Travel Router: $65.00 USD
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.

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 is working with the newer 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.
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.

Each Blonde Guy ArcaOS preloaded computer comes with a standard load of software. This page lists what is in the current pre-load. This list is updated over time to incorporate new essential OS/2 software as well as to keep up to date versions of existing software. When you receive your ArcaOS preloaded computer, you will have Blonde Guy's best installation of the latest OS/2 software.
The recovery USB stick supplied is a bootable ArcaOS USB stick with a backup of the hard drive as delivered. You can boot the machine from USB stick, and perform maintenance functions. The maintenance folder is available on the recovery USB stick. 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.
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.
The installed BIOS is 1.37 and the EC is 1.04. The current BIOS is 1.37 and EC is 1.04.
I made the following changes to the default BIOS settings. Then I powered the Thinkpad down and up.
The Lenovo Hardware Maintenance Manual says to turn off the internal battery before opening the case, then remove 8 screws and pry 8 tabs to open the entire back of the case. The drive was easily replaced.
I booted the ArcaOS USB stick, and in System Maintenance, I prepared the hard drive. Then I used AOSBOOT to install the ArcaOS installer on the hard drive as drive X: (FAT16, 2000 MB).
I installed one bootable volume, H:. The H: drive has a Custom installation that is on the minimal side.
Sound is working normally on the laptop. Audio works well, both external speakers and headphones are working. The following modification is needed to enable sound. The Uniaud driver from Arca Noae provides sound through the internal speakers.
Driver=H:\MMOS2\UNIAUD32.SYS /A:1
The VIOP.SYS driver is installed to make DOS Full-Screen work. DOS Window does not work, but Alt-Home from a DOS Full-Screen allows a DOS Window to work.
Using Suntan Special I run sequences ArcaOS50, apps, games, dev and cleanup. This is saved as the Factory image. This is normally what would be supplied on the computer.
The built-in video is supported by the Panorama video driver version 1.14 or later.
If am external monitor, 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 to switch to and from an external monitor. 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 switch to my external monitor, the computer changes to 1600 x 1200. I enter 1920 x 1200 into the screen applet and reboot for optimum resolution. When I switch to the built in display, the same action is needed.
