Blonde Guy ArcaOS preloaded computers can come with an load of software intended for OS/2 in industrial applications. 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.
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.
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.
This computer had a cursed BIOS. I could not upgrade it using the Lenovo flash update program. Eventually, I found a way.
The cursed BIOS must be updated to version 74 first, and only then will be allowed to update to the latest, version DE. ArcaOS will have video issues unless this update is performed.
As far as I know only BIOS before 74 are cursed.
When the BIOS is old, The video has problems with DisplayPort monitor
and shows only 640 x 480. Use the Windows FLASH update package. You may
need to use WFLASH2.EXE
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 Disk Utility finds the disk, but does not find valid formatting, 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.
UniAud works with /A:1.
Driver=F:\MMOS2\UNIAUD32.SYS /A:1
DOS Window does not work. Alt-Home from a DOS Full-Screen then allows a DOS Window to work.
