Unfortunately there is no "legacy" option available in the bios - only CSM.  And with CSM turned on the video displays - at least enough to get the first install menu and logo.

It would be pretty easy for me to buy a different video card to get through the installation, if that would solve the problem.  And providing that I could then install SNAP and the Radeon X600 after I got AOS v 5.1 installed.

Does SNAP work with UEFI?

Setup & Installation / Install - screen goes blank when pmshell starts
« on: January 26, 2024, 07:08:12 am »
Trying to install on a MSI Pro B550-VC motherboard with a Ryzen 5 5600X and Radeon X600 video card.  The Ryzen 5600x processor has no graphics built into the CPU.   CSM is turned on in the bios.

I created a USB stick for the install.  I get the AOS boot menu where it asks if I want to boot from the hard drive or Install/Maintain AOS.  I pick install/maintain.  The AOS logo shows up for a while and then the screen goes blank.

Tried setting AOS install/boot option to turn on showing the loading of drivers (e.g. Alt-F2)  The screen goes blank right after it says PMSHELL.

As a note:  when I turned on the computer for the very first time the screen was blank for a long time (a couple of minutes) and then I got a message to the effect that video was not UEFI compatible and was switching to CSM.

Anyone got any ideas?

Setup & Installation / Re: Are there any 8GB Nvme compatiable motherboard

I have two run of the mill Dell 27 inch monitors - they aren't even the same exact units but close enough.  Each 1920x1080

I have them hooked up to a  dual-head KVM so that I can share them between multiple computers.  I am using VGA because the Radeon outputs either DVI or VGA and the VGA version of the dual KVM was much cheaper. 

I tried a 49 inch monitor - thinking that I could use the Radeon to drive each half of the 49 inch monitor thought its picuture by picture feature.  But the conversion from VGA to HDMI that the monitor wanted didn't work very well. (I don't think there is a 49 inch that accepts VGA)  And what I discovered is one 49 inch monitor weighs much more than two 27 inchers.  The result being the 49 inch shakes alot when the desk is bumped which doesn't happen with the two 27 inchers.  Plus 27 inch monitors are so cheap now - so I sent the 49 inch back.

Ivan,

Can OS/2 see the full 4gb of memory on your MSI B550A-pro?

Oops - I really meant 4 GB for OS/2 and some more for RAM disk.  Since I think of memory in either 8GB or 16GB units/sticks - I said 8 GB.  I should have said "with a nice linear memory map" - cause that is what I really meant.  I guess I wouldn't oppose a 12 GB ram disk - but 4gb is probably enough.

I am looking for a desktop because I am hooked on using dual monitors - which means SNAP, which means either a built in graphics chip that SNAP supports with 2 outputs, or a desktop so I can use my Radeon x600 PCI card.

ArcaNoae has released a test program that you can run on a perspective computer to see what features/attributes it supports or has.  But I can't realistically take a USB stick into MicroCenter and run it on boxed motherboards. 

Dariusz's idea of an adapter is good - if adapters (PCIe - NVMe) work in OS/2.

But my fear is: everything you can buy now has issues with a non-linear memory map but everything you can buy now has NVMe built it. So I am probably looking at used - not from Microcenter.  < edit - just checked an apparently you can still get the MSI 550A Pro motherboard - so I will be looking at that.  It appears to only have 2 PCIe tiny slots and one large PCIe-x16 slot.  I have seen a PCIe-x1 to PCI adapter so maybe that would work from my serial port card.

Anyone aware of a motherboard that handles nvme and provides os/2 access to the full 8gb of main memory?

I don't see one on the wiki and was hoping someone has experience with building such a system.

Not discounting most of the concerns of Sigurd,  my view of ArcaNoae as a private user is/has been more upbeat. 

While virtualization is certainly a good solution for laptop users who aren't brave/foolish enough to modify their laptop's BIOS  (e.g. to remove whitelist for WiFi adapters), I don't think it is the only future for OS/2 users.  However I did see lots of users with AOS installed in  virtual machines on laptops at Warpstock, 

But the release of EUFI, NVMe and USB3 support shows that virtualization is not the only path forward for OS/2.  It is a path, but not the only one.

ArcaNoae is a business.  I would prefer they stay in business, even if that means making hard decisions on what to work on and not work on based on potential revenue and cost considerations.  I benefit from the things they do release that I need - even if it is not everything I need.  This is just my opinion, but I think it is worth paying for licenses and subscriptions so that ArcaNoae has revenue to stay in business and continue releasing improvements to OS/2.

I was surprised, but pleased, that ArcaNoae released a notice on the impending demise of Hobbes.  I thought the reason was so that people would know what was happening to keep the Hobbes archive working.  OS2voice is the best organization for running Hobbes now - thanks Roderick and all the others for their work on moving Hobbes from NMSU.  And thanks to NMSU for hosting Hobbes for so long.  The OS/2 community appreciates it.

Applications / Drive drop-down empty in Win-OS/2 apps
« on: January 15, 2024, 12:02:11 am »
When I pick Save-as from the file menu in Win-OS/2 apps the "standard" file dialog box has a drop down list for drive letters in the lower right part of the dialog.  That drop down is always empty for all the apps that I have tried.

I can manually specify a drive in the path name of the file I am saving as, but I cannot use the drive drop down list to select a drive letter and see the directories in that drive.

This happens in AOS as well as ECS.

Anyone else have this issue, and/or know how to fix it?

Roderick,

So is your plan to have two sites? Merge what is now os2site with what is now hobbes? Something else maybe?

I ask because it seems like os2site has stuff that is not on hobbes.  I kinda like the idea of the 2 sites being different.  But that is easy for me to say since I am not maintaining either site.

Martin, IAN, Roderick, etc.

Do you think NMSU be willing to permanently redirect the URL hobbes.nmsu.edu to a URL of our choosing?  Or could we buy the URL? 

The hobbes website is pretty simple and straightforward.  I am guessing the archive directory structure matches the directory structure laid out on the web site.   Seems like it would be relatively simple to recreate hobbes website and point the old (current) url to the new server.

Programming / Re: Installing VisualAge 4 on ArcaOS 5.x

One more tip for the Netscape install - size the netscape window as large as you can before starting the install.  On my systems, if I don't size netscape pretty large, the continue button is off the bottom of the screen and you can't get to it.

As for the help system - DB2/v v 7.x uses the same help system.  I believe however that it is a later version and you need to install VAC 4.0 first, then install DB2.  The ReadMe for DB2 explains this.

Also - installing the fix pack will break the links in the help to the sample code.  The samples are still there - you just have to hover the cursor over the link to see where the sample is located, then go to that location manually.

I believe Hyperthreading is an Intel only feature - meaning it only appears on Intel CPUs.  If I understand it correctly Hyperthreading was/is a technology by Intel to provide some of the benefit of multiple cores without actually having all of the hardware of the multiple cores. To quote from wikipedia "Hyper-threading works by duplicating certain sections of the processor—those that store the architectural state—but not duplicating the main execution resources"

Since it is specific to some Intel CPUs you won't find a setting in the BIOS for AMD processors to turn it on or off.

I have heard for years, as Roderick says, that hyperthreading does not work well with OS/2 and should be turned off.  However, I have had some systems with an Intel Northbridge CPUs that supported hyperthreading and my systems appeared to run fine with Hyperthreading turned on. (I didn't know at the time it was supposed to be turned off.)  But I never did a comparison with hyperthreading turned on with it turned off, so I can't say whether it was faster or slower with Hyperthreading turned on.  And - after reading this thread - I just checked and realized that Hyperthreading is turned on on my Thinkpad T530i and has been ever since I purchased it.  Oops.  And I installed AOS 5.1 on that thinkpad, apparently, with Hyperthreading turned on.

Whether Hyperthreading speeds things up or not:  when AOS came out with mulitple processor support for SNAP I turned on the multiple processor support for my AMD 4350 CPU based system (which does not have Hyperthreading) and the Workplace Shell appeared to slow down in certain situations - even while applications like FireFox sped up.  Perhaps it was my imagination.  Or perhaps some software/applications work faster in a multiple processor environment and some do not.

well - now it works for me also.  Probably operator error on my part.

RTAN,

FWIW I agree with Neil that VAC 3.0x is a good choice if you are creating a new app from scratch for OS/2.  I wouldn't worry about the age of VAC v 3 and getting help.  There are plenty of people here on the site that are familiar with that product and can help you when you need it.

If you are intending to build GUI applications you basically have 3 choices with VAC v 3:

1) Code to the Presentation Manager and Control Program API using C or C++.

There are a number of books available for teaching and assistance.  I would recommend "OS/2 2.1 Workplace Shell Programming."  Despite the title the book is really about programming to the PM API.  I believe that book is available online.

2) Code to the IBM Open Class Library (IOC) that is included in VAC 3.x.  The IOC is a extensive set of C++ classes that can be used in place of calls to the PM API.  Coding to the IOC can be faster and easier than coding to the PM API.  But the disadvantages is the GUI part of the library it not UNICODE compatible, and the library was written before C++ was standardized so some of the library classes do not conform to the C++ standard.

This means that if you want to use one of the classes from the standardized C++ library you might have to use the IBM alternative supplied in VAC instead.

I recommend the book "Power GUI Programming with VisualAge C++"  It contains lots of includes sample code.  I believe it is also available online.

3) Use the Visual Builder tool to make your GUI application.  This is a tool for building GUI application/screens by dropping "controls" (parts in Visual Builder terminology) on a composition surface and connecting events, attributes and actions of the control(s)/parts together.  When you click the "build" button the tool creates source code for the application that you then compile with the VAC compiler.

2 books: "VisualAge for C++ Visual Programmer's Handbook",  and "Object Oriented Application Development with VisualAge for C++ for OS/2"  Both books will guide you step by step through building a simple application.  I believe both books are available online.

If you want to program a GUI application in Rexx you might consider DrDialog.  It is more powerful than MAID but simpler (and less powerful) than either VxRexx or VisProRexx.  It is IBM employee written software and has always been free. 

Hope this helps.

Jan-Erik,

I can't download your library.  Perhaps it is because of the extension .7z?
