Lenovo Thinkpad T450s (Phenobopeep)
This IBM Thinkpad model is a portable computer, with powerful CPU and graphics. The VGA adapter is suited to an external monitor. 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.
Support for an external WiFi bridge is installed.
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 computer arrived on Dec. 17, 2018. The hardware maintenace manual explains how to upgrade the hard drive.
The installed BIOS is 1.33 and the EC is 1.04. The current BIOS is 1.35 and EC is 1.04. I decided not to update 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; Otherwise ArcaOS 5.0.3 USB stick would not successfully boot. I set the Display is set to Analog VGA, so that display goes to external monitor if one is connected. It is normally important to disable Hyper-Threading, however, there is no way to do that on this BIOS.
Hard drive preparation
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, K:. The K: drive has a Custom installation that is on the minimal side.
Sound is working normally on the laptop. Audio works well, but external speakers or headphones are required. The following modification is needed to enable sound.
A fix included in ACPI 3.23.10 allows 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.
There is not yet support for the internal WiFi. Instead, support for two external WiFi devices, the Asus RP-N12 Wireless N300 Range Extender and the TP-Link Nano Router is provided.

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.
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.
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, USB 3.0 is under development at Arca Noae.

Recovery USB stick
The recovery USB stick supplied is a bootable ArcaOS USB stock with a backup of the hard drive as delivered. You can boot the machine from USB, and perform maintenance functions. The maintenance folder is available on the recovery USB stick. The factory backup is stored in the \Factory directory on a second volume. 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.
