Storage / Re: Boot from iscsi or fiber channel
« on: February 13, 2024, 05:23:27 pm »
What about fiber channel, is there any FC adapter known to work with OS/2?
Yes, of course. The Compaq StorageWorks around 1999/2000 supported OS/2 Warp Server (

It's even the advanced edition in the later packaging.

APL2/2 Advanced provides the following additional features:
 o  Interfaces to the DB2/2 database system
 o  TCP/IP Socket Interface
 o  Cooperative processing across a TCP/IP network, providing the
    capability to:
    -  Share variables with MVS, VM, AIX/6000, OS/2, and Solaris
    -  Share variables with remote auxiliary processors for
       access to graphical user interface (GUI), database, and
       other system services
    -  Run a session manager communicating with an APL2
       interpreter on a remote platform
    -  Distribute parts of an application across multiple
    -  Build a network server

PCs cannot replace PLCs, a Soft-PLC is not a PLC CPU equivalent. The same applies to Slot-PLCs.

Solutions based on OS/2 were mostly used for SCADA or HMI systems - completely irrelevant these days.

Applications / Re: IBM WorkSpace On-Demand on VMs ?
« on: October 09, 2023, 03:14:43 pm »
WSOD 2.0 can also use PXE.

For running WSOD 1.0 you can simply create 3 VMs:
1. Warp Server
2. Warp 4
3. Workspace On-Demand
The installation is straight as all fixes are included with WSOD.

The 3rd VM should be modified by using a ROM from PRORPL.EXE (Intel) or AMD's RBOOT.ROM.

Networking / Re: WinOS2 and WinSock
« on: November 12, 2020, 12:25:34 am »
I installed some Win16 networking application, and I realized that it won't work without some kind of WinSock support.

Apparently I've forgotten how to add WinSock support. Anyone remember this one?
There is no reason for adding the support. It should be available from IBM TCP/IP for OS/2 by default (VDOSTCP.SYS). Only configuration for \TCPIP\dos\etc\RESOLV should be done.

Storage / Re: ArcaOS USB floppy drive letter assignment

Check the CONFIG.SYS for the entry BASEDEV=USBMSD.ADD ...
and add /FLOPPIES:1 /A_USAGE:1 to this line.

Hardware / Re: OS/2 and the Mainframe
« on: March 13, 2020, 11:32:28 pm »
I have these questions:
1) Which are the "Support Element" software versions that runs on OS/2 ?
Please give us a FRU and I can check.

2) Some Mainframes came with a Thinkpad with OS/2 preloaded, how it is connected physically to the mainframe? Serial/Parallel/PCMCIA/Network?
It's not connected physically. Usually a console controller was used.

3) Some other mainframes came with a PC with OS/2 (I think it is called HMC -  Hardware Management Console ). how it is connected physically to the mainframe?
Please give at least a part number - there were dozens of devices which run internally OS/2 for different tasks.

4) I don't think I can find a list of which mainframe models used to be compatible with OS/2's HMC, but I will like to build one.  I only have the Multiprise 3000 and the IBM z890 on my list, if someone remember some other model that has OS/2's HMC or know where to get this information, please let me know.
What's the question here? Do you want to operate 15 to 20 years old systems and need replacement parts today? It would be cheaper to use emulation or a zPDT.

1) There was a PCI card (also some older ISA) called P/390 that used to be "a mainframe in a card" that you plugged into a PC so you can do development and testing for mainframe applications.
In fact there were different PCI adapters. And there was never an equivalent ISA solution. It's not helpful to mix here different architectures. Neither a PCI nor an ISA adapter would fit into a PC. The S/370 solution for the XT consisted of 3 boards and for the AT of 2 boards. Non of those adapters is required for "development and testing" of "mainframe applications". You can simply use the usual development environment via 3270-sessions or one of the GUI solutions.

Perhaps I can add a list of these programs and then a conventional VIO window gets started, or I define a command /VIO where the user can start a VIO window in a command.
This may only work for programs that don't use the following calls:
  • KbdRegister, KbdDeRegister
  • MouRegister, MouDeRegister
  • VioRegister, VioDeRegister, VioGetFont, VioSetFont, VioGetPhysBuf, VioGetState, VioSetState, VioModeUndo, VioModeWait, VioSavRedrawUndo, VioSavRedrawWait, VioScrLock, VioScrUnLock
Most likely, session management calls are affected also.

VirtualBox doesn't support XDF disk image files. Virtual PC can be used to install from them but not from physical floppy drives. The VHD that contains the installed system can be transferred to VirtualBox.

Programming / Re: fully programmatic menu creation?
« on: September 04, 2019, 07:34:21 pm »
but apparently not as straightforward as calling single API methods like win32's CreateMenu, AppendMenu, SetMenu, etc.
At least the mentioned functions will behave the same as their Win32 counterparts.

Programming / Re: Rexx Socket / SMTP
« on: May 03, 2019, 06:23:03 pm »
IIRC, attachments have to be base64-encoded,[
Not true, even for old-school SMTP.

but I don't know how they are appended to the message text.
Please take a look at MIME.

RXHELO which utilises RXSOCK is a good starting point, but nowadays authentication features should be considered unless you're running an MTA for in-house operations.

Setup & Installation / Re: Citrix Multiuser 2.0 Problems
« on: April 14, 2019, 12:34:23 am »
At the picture there's FAT, but on later installation I changed type to HPFS. My VM hard drive is only 20 MB.
That's to small, please use a proper partition size (200 - 400 MB). When using VirtualBox the host adapter support should be changed to the BusLogic SCSI adapter. LADDR support on the installation disks needs to be updated by including BOOTBID.BID. Using ESDI-506.BID for emulated IDE drives can cause more problems including the symptoms shown on the mentioned pictures. Furthermore the serial ports for communication should be setup properly in VM configuration.

Programming / Re: DBExpert / Driver
« on: April 09, 2019, 02:13:10 pm »
I will take a closer look at the SDK/ZIP file and hopefully it will help me.
Or you can save time by ignoring it. Visigenic ODBC (the later VisiODBC) is a different ODBC driver product from a different company Visigenic Software, Inc. which was acquired by Borland in late 1990s.

The Q+E ODBC developed by Pioneer Software which was renamed to Q+E Software and later bought by Intersolv in 1994 is based on ODBC Version 1. The book mentioned in the former answer can still be used. Intersolv is no longer existing, it became Merant when bought by Micro Focus. The DataDirect ODBC stuff was branched out and is now available from Progress Software.

ODBC is the API. There seems to be some confusion about the right terms for ODBC driver manager, ODBC driver and ODBC driver implementation in the former answers.

Applications / Re: Converting .BOO to PDF ?
« on: April 08, 2019, 10:42:46 am »
The process of conversion depends on different host-based programs (DCF, BookMaster, ...). Of course some of them can interface to OS/2 workstations.

At  least it should be possible to create lower quality printouts to PostScript or PDF targets. Simply follow the directions in "Installing, Managing, and Using the Online Library" (GC31-8311-39). In IBM Softcopy Reader or BookManager READ you can select all topics to print, but it will be quite useless without working indices or content list.
