Desktop computer (Umbopeep)


This used desktop computer is compatible with ArcaOS. It features an Intel i5 dual-core processor, 8 GB RAM and a 500 GB hard drive. A 2 TB solid-state hybrid hard disk is an optional upgrade.

This computer is configured to boot ArcaOS. No Windows is installed, nor are instructions provided to install Windows without harming the ArcaOS installation.

ArcaOS installation

A boot menu offers either the ArcaOS installer, located on drive X: or the ArcaOS operating system, located on drive J:. A generous amount of free space is available for operating system installation.

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.

Driver Notes

Only 512 MB RAM are available using the IBM OS/2 Loader. Using the ArcaOS Loader 3437 MB are available. The balance of the 8 GB RAM can be used as a RAM drive.

The network driver is MultiMac32-E1000. The wireless network has no OS/2 support. According to the Arca Noae roadmap, a driver and supporting software will be written for this hardware.

I used OS2AHCI for disk support, so the computer BIOS should have the disk support set for AHCI.

Arca Noae USB stack 11.17 works well with Lars Erdman's USB Audio driver and a Trond USB audio adapter.

To get the USB audio driver to work, I used version 223. I installed ArcaOS with no sound driver. Then I installed the USB audio driver, then the WAV audio driver. It can be tricky to get the audio driver to work.

ArcaOS Installation

I installed ArcaOS on drive J: with minimal options. Most programs were added by Suntan Special afterward.

DOS window sessions work after this:
add /int10textgrfxsafe to vsvga.sys device driver in config.sys
add mode co80; cls to autoexec.bat

I installed Suntan Special, I run Suntan Special sequences ArcaOS50, apps, games and cleanup. This is saved as the Factory image. This is normally what would be supplied on the computer.

Sound support is great using the default UniAud except that the sound comes only from the built-in speaker, and nothing from the front headphones. So external speakers are not going to work with Uniaud. To fix this, I uninstalled Uniaud and replaced it with Lars Erdmann's USB Audio driver and a Trond USB sound adapter. Sound works very well.


The computer is set up to connect via ethernet cable. The network interface has been set up to configure automatically.

The USB 2.0 ports support keyboards, mice, scanners, thumb drives, cameras, MP3 players, external hard drives, floppies and CD Writers.

The DVD drive can read and write DVD and CD media.


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.

Suntan Special was used to bring the system up to date on May 19, 2019.

Recovery DVD

The recovery DVD supplied is a modified bootable ArcaOS DVD with a backup of the hard drive as delivered. You can boot the machine from DVD, and perform maintenance functions. The factory backup is stored in the \image\Factory directory. The backups are simple zip files. You can use 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.

Disk Layout

The disk is partitioned into ArcaOS installer and ArcaOS volumes. You can use the ArcaOS volume (J:) as is, or you can create your own ArcaOS volume out of the free space.

This is the layout for a 500 GB hard drive.

To buy this computer, fill out an order form and submit it to Blonde Guy. Blonde Guy will review your order and send you an invoice, payable using PayPal or any major credit card. If you prefer to pay by check, note that in the notes field of the order form, and I will e-mail you an invoice payable by check.

The final price of the computer depends on tax, shipping and options.

On the order form, choose the appropriate ArcaOS license. For a business, the commercial license is required, otherwise a personal license is fine. The personal license comes with a 6-month subscription for support and maintenance. The commercial license comes with a 12-month subscription.
