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.

Power Consumption

Power consumption is 30 Watts (25 Watts), measured with the computer is booted to the desktop. In use, the computer can consume about 70 watts. This computer consumes less than 1 Watt if it's plugged in, but switched off.

Disk Layout

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.

Software

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

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.

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 BIOS is updated via a BIOS update CD-ROM.

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

With the new 12.07 USB drivers, USB 3.0 is working. I believe most issues are now worked out, but updates to the USB drivers are expected in the future.

The Disk driver is OS2AHCI with native command queueing enabled. UniAud works now works without command line modification.

BASEDEV=OS2AHCI.ADD /N /F /V:2

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.
