Hardware / Re: OS/2 on Virtualbox with 8 COM ports
« on: May 06, 2021, 04:16:25 pm »
I'm an OS/2 consultant. I have some picture of the few remaining OS/2 users. There are quite a few industrial automation programs from the 1990s that relied on serial ports communicating to programmed logic arrays to do their machine control. Many of these machines only lack a working OS/2 computer with serial port support to work again.

There is also the dongle situation, which traps users on old hardware. I worked at a dongle manufacturer, and I know that OS/2 was always supported, but never was a large part of the market.

OS/2 developers have the source code for the IBM serial port driver as a part of the device driver developer kit. This support is limited to hardware available in the 1990s, but if hardware documentation were available for new serial cards, someone could extend support of the existing driver.

I don't want to exaggerate the size of the opportunity. Most of my industrial customers have migrated to newer platforms. I'm hoping someone here has a clearer idea of what would be needed to extend the device driver support.

eCS definitely boots from a USB DVD drive.

Unless it is a museum piece, ArcaOS does not support the wireless feature of your laptop.

I had the same flashing - at some point. I had to order the drives in BIOS so the NVMe drive was first. I had to install AirBoot on the NVMe drive. I had to make sure that the NVMe driver came before other disk drivers in Config.Sys. And I had to make sure that ACPI was not called with /VW.

For Ivan's case, it might be enough to run chk4dll on a system with rpm/yum and the target application installed, then parse the output into a list of files to be zipped. You could automate that process with Rexx.

I can't really see the developer being bothered to do that, but someone who wants to make a non-rpm/yum version could do so without much trouble. Just run yum update and then use chk4dll and your own Rexx script to recreate the distribution.

Although, as Dave Yeo points out, you might have to update as the rpm repository changes. But that only happens twice per day. You could recreate the distribution every twelve hours and you'd be good.

yum install qt5
If you already have simplebrowser running, you already have QT5 installed.

I got a Vantec PCIe adapter, and installed a 250 GB Samsung 980 PRO (PCIe 4.0 NVMe M,2). It works well, after the driver loads, but I cannot boot from it. The problem is that it is mounted on a plug in card, that the BIOS doesn't know about, so it won't boot from it (because it doesn't know it is there). Air Boot also cannot "see" it, because BIOS doesn't know about it. Most (if not all) machines cannot boot from a plug in card, if the BIOS doesn't know about it. This is true for USB too.

If you have a machine, that knows about the adapter, it should boot from it.

Then again, it really doesn't make much sense to waste one of those things for boot code, unless you boot 14 times a day, or it is your only choice. I am still thinking about how to use it effectively. At least it is non volatile, so it remembers what was put on it, unlike what the RAMDISK does.

I'm booting just fine from a Lenovo ThinkCentre M900 with a StarTech PCIe-4x NVMe card. It's easily twice as fast as a SATA SSD. As far as being a waste, new machines only have this type of drive, so we need booting support.

Hi Mike, can you please let me know the model of the Lenovo docking station that you are using? If it is not much to ask, can you please take a pci.exe report without the dock and with the dock to notice the difference, so I can add it to the OS2World wiki?

Hi Martin,

I am using the Thinkpad Pro Dock 90W. Please see attached picture for the type plate.

Kindly note that I have the USB3 feature of the X250 disabled, due to problems with the AN USB drivers. Even if only USB2 is enabled I need Lars Erdmann's drivers to use my external keyboard and mouse.


I have the same dock. It does not work well with Arca Noae USB. If you must use Arca Noae USB with this dock, set USB to Auto in the X250 BIOS and use USB 3.0. Even then I need to unplug and replug the keyboard and/or mouse to get it to work. Before 12.08, it didn't really work at all. Once in 50 times, it traps. If you get a trap screen for this Dock, post it here or open a ticket at Arca Noae.

If you want to boot from NVMe drive, and you use AirBoot, how are you going to install AirBoot on NVMe drive? That's why you need to boot from the installer USB stick.

If you have another drive besides NVMe one, better read this page from the Arca Noae wiki.

I have now done it using the ArcaOS 5.0.6 USB stick. I'm sure a Wiki entry from Arca Noae will come soon, as I have reported the result to the tester's list.

You'll need to edit the Config.Sys in the pre-boot menu to comply with what it says in the NVMe readme. The PSD line needs to NOT have /VW

If you install, you need to edit Config.Sys at the end of Phase 1 with the same changes the pre-boot menu got. After that, it should work.

Thanks, the hint about "1" was what I needed.

wrong: CustomVideoModel
right: CustomVideoMode1

I now have ArcaOS running at 1920 x 1200 x 32 in full screen mode.

I carefully tried jailbird's instructions above, but I don't see a 1920 x 1200 x 32 selection appear.

I didn't notice before, but I do see 2 lines containing 1280 x 1024 x 16M in the OS/2 screen applet. Next step is to repeat the ArcaOS installation.

Hardware / Re: Virtualbox, eCS and USB 12.08

I just installed USB 12.08 on my Virtual Box system. No problems observed so far.

Maybe it is widescreen that is causing your crash? ;)

Thanks for the suggestions.
I am using Virtual Box 6.1.18 under Windows 10 64 bit (and also Ubuntu, but I checked your suggestions under Windows)
I left monitor unselected, as I had seen Martin's page with no monitor, but wide screen working
I am using VBoxVGA and I increased video memory to 32 MB
I had been trying 1920 x 1080 x 32, but then I saw your suggestion, and I changed to the native 1920 x 1200. Both Windows and ArcaOS are fine with 1920 x 1200 x 32. Unfortunately, this change did not get VirtualBox to cooperate.

My OS2Addtions are dated 8-15-20. These do not have VBXGRADD.DLL

I am using Ubuntu Linux, but I also have a Windows 10 host. I am quite unfamiliar with Windows 10 and Ubuntu, but I thought Virtual Box might be helpful to develop. I've tried to follow your instructions, and those at Arca Noae, but nothing seems to set that resolution.

Your helpful Wiki helps me see that monitor definitions are not the answer. But I'm still unsuccessful at adding any wide screen video.

I tried VBoxManage and I am using the same GRADD.DLL as Martin. But so far no joy with getting a wide screen resolution. The screen applet suggests that I select a monitor to enable higher resolution, but offers me a list of monitors from 1996. Did anyone using a wide screen select a monitor? What did you choose?

For what it is worth, I do see a slight flicker to the cursor at 1280 x 1024. It's not crippling, but I think original poster is right that it is a little slow.
