I am not certain. But even when a trademark its registration has not been extended by the trademark owner. Then I am do not think you can just use.
As IBM still retains ownership of the word OS/2.  This might also vary from region to region in the world.

No, that applies to copyrights and automatic grants of IP ownership in general (for most countries anyway, those that are fully signed up to the Berne convention). Trademarks are different, they have some aspects of IP but are mostly grants of goodwill, you have to register them, keep the registration current and defend them, otherwise you lose the exclusive rights to use them.

IBM & MS can object to you registering the OS/2 trademark, but they will have to show that they are currently using it, show that you are not currently using it and are thus attempting to register it in bad faith, and will have to show a valid reason for not having maintained the trademark registration. They cannot stop you from using it on t-shirts or other products, since they no longer have any claim on it.

The CE world is full of trademarks that have at one time been taken over by unrelated companies or individuals by re-registering the trademark rather than buying them from a trademark owner, for example Nikko, Telefunken, Universal Audio, Moog, Scott, Audio Note, etc.

Programming / Re: New frontends for GCC 13...

...due sometime next year..

When the GCC 13 code gets closer to release, I'll look at building it, noting that GCC 13 will drop support for STABS debug code, so we won't be able to built debug code....

The M2 integration was supposed to happen with GCC12 (and funnily enough with GCC 0.x as well), so I am not holding my breath ...

hi,
some news... i still can't tell what happen exactly, but it might be the TI 486 SXLC2 having some troubles with OS/2.
but i can't easily swap with the original 386, as i soldered the TI and don't plan roll back anyway.
Should not be a problem with the CPU on its own, I ran OS/2 v3 on an ISA board with a Cx486SLC for years, up to fixpack 4x, the only difference between that chip and yours is a bigger cache and optional clock doubling. If you can get hold of TI's utility software package that they distributed for the chip, you can try toggling the clock doubling feature on and off, but I doubt that would make a difference.

I sold a number of these as upgrade chips (on a socketed PCB typically) and as budget replacement motherboards in its day and while we did provide the TI software package to people, no-one ever seemed to use it since they were more or less plug and play.

IBM did supply updated firmware and configuration software for some of those ISA based PS systems, such as the PS/1 386sx, as they had some problems with booting OS/2 32bit but I have no idea if that applies to your system.

Applications / Re: DOS version on ArcaOS
« on: July 27, 2022, 02:22:27 am »
There are DOS 1 programs, DOS v1 was quite different, no directories, FSB's, making it more like CPM.
It is also possible to boot CPM86 on OS/2.

DOSPlus works better than CP/M86 under OS/2, and it runs all CP/M86 programs and most DOS programs as well, it can be downloaded for free from the official DR site.

Setup & Installation / Re: Quick question about boot manager
« on: January 08, 2022, 05:08:23 pm »
I want to setup a replacement computer system with multiple operating systems on it.

I have learned that the boot manager that comes with ArcaOS is useless on any of my AMD Ryzen based systems - it does not display any of the menus so it is impossible to select an OS.

Before I start this project I would like to know if anyone is using the old OS/2 boot manager in such a situation.  I know the primary partition limitations and since I only want three operating systems on this new system (Boot Manager, OS/2(ArcaOS), Linux Mint and Win7).  There will be several hard disks - the number will depend on how well the system will work.

The reason for this is because I am fedup with having 5 or more computers running at the same time all feeding into a KVM switch and two monitors, also on a HHDMI switch.

Any information and comments?  Thanks in advance.

I used the boot manager built into Windows 8 to boot into OS/2 and other OS's, a few years back. I have not tried it with Win 10 as I simply use the EFI/BIOS emulator switch built into the UEFI firmware to switch between two disks, one with GPT and one with MBR.

It is possible to run DOS packet drivers in a DOS session if you disable the DOS/2 networking, but not recommended, FTP Software (the company) also sold a TCP/IP stack for OS/2 that had a VDD that allowed DOS sessions to use DOS packets via emulation, but alas that is impossible to get hold of these days. The Essex Systems stack also had some VDD trickery, but I cannot remember it it supported the FTPS packets specification.

Is it true these older OS/2 TCP/IP and NetBIOS over TCP implementations used proprietary APIs which limited their use to only the network applications/services that were distributed with these packages?

The stacks were mostly compatible when using the same protocols, the low level or packet interfaces on OS/2 1.x varied from provider to provider however, for OS/2 2x this matterred less since NDIS was provided as standard and most stacks just layered on top of that (NDIS was available for 1.x, but not supplied as standard, except possibly with 1.3).

Hi

So, I need to  find the documentation inside the  "IBM TCP/IP for DOS 2.1.1 Programmer's Toolkit".

On the "IBM TCP/IP VERSION 2.0 FOR OS/2" announcement there are some references to something called "DOS/Windows Access Kit"

Quote
DOS/WINDOWS ACCESS KIT:  This facility allows DOS applications written to the IBM TCP/IP for DOS Version 2.1 programming interfaces, and Windows applications written to the Windows Sockets API Version 1.0 or Version 1.1 specifications to run in an OS/2 environment on top of IBM TCP/IP Version 2.0 for OS/2.  This product requires the customer to have the OS/2 Version 2.1 operating system installed.

I'm still trying to find something on a package of TCP/IP 2.0 for OS/2, but I still haven't find that documentation.

Regards

The OS/2-DOS TCP/IP interface is basically WINSOCK

VDOSTCP.SYS emulates a Windows TCP/IP stack interface, MicroWeb uses a DOS TCP/IP stack (mTCP) that relies on DOS packet drivers, which are different to the Windows packet drivers, they are a bit more like early Unix an Linux packet drivers. It might be possible to configure the program to use the native stack .

It is possible to run DOS packet drivers in a DOS session if you disable the DOS/2 networking, but not recommended, FTP Software (the company) also sold a TCP/IP stack for OS/2 that had a VDD that allowed DOS sessions to use DOS packets via emulation, but alas that is impossible to get hold of these days. The Essex Systems stack also had some VDD trickery, but I cannot remember it it supported the FTPS packets specification.

You can also try the Archane browser, it used to work with Windows sockets/packets in an OS/2 DOS window, it saw some updates in the last two years.

Thanks for the heads up.
FYI, Here it is the link: ftp://ftp.netlabs.org/pub/uniaud/Uniaud-20211023.exe

Regards

Is there a parsing bug in the forum software? The link shows up correctly as
ftp://ftp.netlabs.org/pub/uniaud/Uniaud-20211023.exe
However the actual link is ftp//ftp.netlabs.org/pub/uniaud/Uniaud-20211023.exe i.e., the : is dropped

Hi Martin

No idea if DeskMan/2 is still available http://www.devtech.com/DeskMan/index.html


You can toy around with a slightly older version here: https://winworldpc.com/download/51cadba9-f65b-11e8-9b71-fa163e9022f0

Applications / Re: Time sync in VirtualBox guest off by 1 hour
« on: July 18, 2021, 10:15:16 am »

OS/2 doesn't adjust to daylight saving time anyway. Of course, I can set daytime (if I run it) to take DST into account, but I wasn't running daytime while using the additions.

Mine does, what am I doing right?

Applications / Re: Time sync in VirtualBox guest off by 1 hour
« on: July 16, 2021, 11:26:54 am »
The VM reads and presents the system time as the host operating system presents it, this means that when you install a guest system you should always instruct the guest operating system not to adjust to daylight savings time, and not to use internet time correction/lookup. It is getting the correct time from the host anyway.

Otherwise both the systems will correct themselves during DST changeovers.

Setup & Installation / Re: OS2 Warp 4.52 "vdi2hardware" result
« on: June 06, 2021, 03:07:41 pm »
I have done this for zonks, I believe there was a small article on the eComStation Facebook page that I wrote on the subject ca 2011, that was removed by Facebook when they changed the rules on article and file permissions when they split groups into groups and pages. I never bothered restoring it elsewhere since no-one ever showed any interest in the technique anyway, just like there was no interest in running OS/2 in a Hyper-V container.

Although in general it is very helpful, there are a few issues doing this, while VB etc. are highly compatible with real hardware there are edge cases of incompatibility, you can end up with an image that boots on VB but not on real hardware and vise versa. It can sometimes by tricky to place an image onto a drive correctly especially if you have multiple partitions and boot drives, for those cases investing in DFSee becomes an absolute must, alignment issues are frequent with any sort of solid state media for instance. The weird behavior of the VirtualBox image manager in recent versions can make maintaining a large  number of VBox images and copies a real pain (unlike VirtualPC, VBox registers (and re-registers) each image into a database). Each version of VBox introduces a new collection of bugs which can throw a spanner into the works, these get fixed eventually but OS/2 is not high upon their priority list (and they are downright hostile to ArcaOS), not a huge issue with images but this makes install in-place frequently impossible on modern VBox which was relatively easy on older VBox versions. In-Place installs were extremely convenient since you could remount the drive on VBox in you had any problems on real hardware. On older versions of OS/2 getting data onto the virtual machine can in some cases be much more time consuming than on real hardware, weirdly enough. etc etc etc

I only really use this technique these days for when installing "legacy" versions of the system, that means I do not have to bother with floppies and I can get the system into a fixpack state that will actually run on the hardware (memory & disk size & driver issues etc). Apart from that and for the fact that I already have a large collection of ready made VBox images, I am not altogether sure I would use the technique except for installing onto systems that run on consumer solid state media eg. embedded systems with SDCards, thin clients with Compact Flash drives or old IDE PC's with CF adapters. In those cases it is very quick, just plonk a converted VBox image onto start of the SD drive and then create other partitions as needed from the install.

I am currently setting up a couple of old VIA C3 systems for compatibility testing, basically each system has 2 or 3 "legacy" Windows installs on primary partitions and a host of various "common" OS/2 versions in an extended partitions. I had intended to convert and copy already made basic installs from VBox onto the extended partition but in the end it actually made more sense time wise to buy a floppy emulator off eBay, load it with a large collection of OS/2 installer floppy images and install from there.

Using PCE rather than VirtualBox also has some advantages since Windows can mount the PCE images directly, you can load software onto the PCE image that contains a windows readable partition type directly from the file manager or folder. It also has a better hardware compatibility in some cases.

And remember you can also go the other way round, DFSee can easily convert your existing OS/2 installs into VBox images.

Hardware / Re: IBM Thinkpad with floppy drive
« on: May 26, 2021, 08:42:47 am »
As far as an UltraBay Floppy that can be swapped in place of the CD drive, I think the T540p series is the last one.

https://www.blondeguy.com/computer/strobopeep.html

I thought the ultrabay 2000 was the last ultrabay that was hooked up to the legacy controller, was there an internal floppy drive available for the 540?
