External WiFi

Using a travel router with a desktop can free you from a wired Ethernet connection. I use the Mango Travel Router to access local WiFi or my phone's hot spot. Mango 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.

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.

Preloaded Software

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.

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.

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.

ArcaOS Installation

With eBay systems, it's best to do a throrough wipe of the hard disk before beginning. OS/2 and therefore ArcaOS, is very picky about drive geometry. A disk laid out by any other operating system will likely not work under OS/2.

I prefer to let Disk Utility on the ArcaOS installation CD do all the work. I boot the DVD, get to the start screen. I pick System Management, and then Disk Utility. This will have several possible outcomes.

If it does not find the disk at all, then perhaps the disk is is partitioned using GPT instead of MBR. The remedy for this is described on the following web page.

Installing ArcaOS over Windows 10

A second possibility is that Disk Utility finds the disk, but does not find valid formatting. In this case the following screen will appear. In this case I simply allow Disk Utility to fix the problem, and reboot.

Disk Utility

** Problems were detected in your disk layout. The problems are listed below.

We may be able to fix these problems for you; see below for details. Please note, however, that we cannot be held liable for any damage or lost data that may result from this action.

The following problems were found:

* There is no valid partition table on the disk. A new partition table must be written before this disk can be used.The disk appears to contain no data, so this operation should be harmless. However, if it does contain data which OS/2 has failed to detect, any such data will be lost if you proceed.

The above problem(s) must be fixed before you can use this disk with OS/2.

If I have fixed the disk using DiskUtility or other procedure, then I run Disk Utility again. If it says "No problems found.", then I proceed to lay out the disk paritioning that I want using "Manage Volumes (Graphical)."

Once volumes are laid out, I can proceed to install ArcaOS, or use the Blonde Guy Recovery DVD to restore a backed up ArcaOS installation.

Driver Notes

The Disk driver is OS2AHCI with native command queueing enabled. UniAud works with /A:1.


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.
