There is an ex-library copy of the (excellent BTW) "Design of OS/2", going cheaply on eBay right now, if anyone is interested ...

Setup & Installation / Re: Booting Warp 4 installer in VirtualBox
« on: February 07, 2017, 04:44:59 am »
Warp 4 works, however there are some differences vis a vis an eCS installation.

Turn nested paging off

Download updates to the three install diskettes, either individually or one of the already made packages available on the net.
You may need to update the files on the disk image again after initial install as the installer sometimes places outdated files from the CD rather than updated files from the diskette.
Edit: Placing "copyfromfloppy=1" on the end of the config.sys file on the floppy should take care of that.

Do not create a virtual machine that is "too big", i.e. memory should be no more than 512mb and disk image no more than 4GB, after you have installed the system updates to FP14/15 you can increase the memory and disk size allocation.

Setup & Installation / Re: OS/2 and Hyper-V
« on: October 29, 2016, 08:37:06 am »
A couple of years back I installed eCS2 in a hyper-V container and by nicking a few extensions (not all worked) from VPC I managed to get a very usable system with a few caveats, including the ability to boot the system from eCS inside the container but without booting the Windows system, which is quite a neat feature. I stopped using it due to the fact that Windows took over ownership of the visualisation features of the chip if Hyper-V was enabled and refused to hand it back even if it was disabled, and that made all other emulator systems non-functional including VBox and VM-ware and as I had almost 20 years worth of images dating back to the 90's this was unacceptable, if a bit sad.

No idea if this was a bug that has since been fixed or if it is an architectural problem with the technology.

Just a WAG, but older versions of OS/2 (before the last couple of updates to warp 3, as I recall) require a BIOS setting to be set ON. It is something about using OS/2, if it exists.. Newer versions of OS/2 need that setting to be OFF. If the setting is not there, don't worry about it.

The OS/2 setting in BIOS is for OS/2 16 bit only, e.g. it should OFF for anything but OS/2 1.x.

Hi guys, I am modifying the time and localtime functions. Trying to squash some bugs I noticed when I used the functions along with strftime in some test programs I compiled. I will check for the make file but I don't recall seeing one. I will check again.  This is where I found the source for 1.9:

I will let you guys know how it goes.
That is the release source, which is years old. The mailing list and website for OpenWatcom are down but you should be able to access the trunk here:

Although many of us are actually using this fork:

Applications / Re: Program object question
« on: August 19, 2016, 04:40:09 am »
Virtualbox 5.024
OS/2 Warp 4.52 unofficial fixpak 6

Hello all, is it not possible to have environment variable substitution in the Working Directory field for program objects?

For example: the program object for the text editor. If I have the HOME environment variable set to c:\home\adam and I want the Text Editor's Save As dialog box to always open in my home directory is it not possible to just specify %HOME% in the working directory field for the Text editor's program object? I have tried using %HOME% and that doesn't work. I have tried several different permutations but nothing has worked yet. I am beginning to think it just doesn't support variable substitution.

The home variable is an import from UNIX and most OS/2 applications do not "see" it unless specifically written to do so, you are meant to explicitly   give the program a specific working directory or no working directory at all, only a few Windows ports such as StarOffice require a working directory AFAIK. Remember that the OS/2 UI is built on O-O/CUA principles and sort of expects people to sort "objects" into project folders (real or virtual folders, and actual files and/or shadows) and work from them, the concept of a home tree as in UNIX is counter-intuitive to that way of thinking.

Setup & Installation / Re: How to boot without Boot Manager
« on: July 10, 2016, 05:07:46 am »
I currently have a system with two disks. Disk1 has Boot Manager  and Disk2 has a couple of partitions marked as Bootable.

I want to remove Disk1 but cannot install BM on Disk2 and can't mark either partition on Disk2 as startable - at least can't find an option for doing this via LVM.

How do I go about booting from Disk2?

Old question I know but try Airboot (, in addition to replacing boot manager it has more flexibility and like BM it allows you to assign drive letters so you can for instance have multipile C boot partitions across multiple drives.

I'm now working on developing the LibSF assembler (lasm) to get my Microsoft MASM 6.11d source code to compile. 
Why not use one of the WASM derivatives that are already MASM 6.x compatible?

General Discussion / Re: Dumping the Wiki
« on: May 21, 2016, 12:13:06 pm »
Hi John.

It is a MySQL database, just that when I export it, it has all the tables for userID and password (salted).

So I would prefer that someone can dump the wiki externally without that information. Also it can be nice if anybody on the internet would like to have a backup of EDM/2 and the OS2World wiki will be also able to generate it.

You can do that via phpmyadmin, just choose the fields you do not want exported when you do a backup and the program pumps out a compressed backup file, phpmyadmin comes as standard with most php installations, you can also export to comma delimited file and simply remove the fields you do not want exposed with a spreadsheet or a database tool, but it is easier just to do a phpadmin backup.

BTW, the password fields should be encrypted AND salted, not just salted (salted = randomised and justified, a dictionary hack prevention to be used with and not instead of encryption)

Anyone familiar with django?

Is it available for OS/2?

It does run on OS/2, but what exactly are you trying to archive?

Setup & Installation / Re: Thinkpad t61

Which machine and how are you installing? Is there a log file to look at ?
Not what I could see an it is on an hp dx2300 compaq with 512 MB and a pentium processor running at 3.00 GHZ or a dx7400 I don't remember which. And I am installing it from cd-rom
Could it be a hard drive size issue?
It should fail with another message, but you system otherwise seems compatible with anything from Warp and up, does the computer have a floppy drive?


For LIBC, do I just tack the .DLL(s) to OS\DLL? And would the same process apply to the emx runtime for OS/2?

the LIBC dll's can go in any folder that is in the LIBPATH, OS2/DLL is a good as any.

For EMX runtimes, you can download the WPI version and just use the installer or read the README that is included if you want more than just the runtime, another common OS/2 runtime that is good to have on the system is the Watcom Visual REXX runtime.

I was reading recently that LPEX was one of the best program editors and I'm tring to track it down to have a look at it.

I believe it was boundled with IBM's VAC++ for OS/2.
It is bundled with VAC++ 4

For REXX, your best bet is definitely E it has an excellent REXX support, but it may help to track down some of the enhanced packages for it as well, there is a seriously capable editor hiding behind that simplex  interface.

Generally my favorite editors are no longer available, namely Preditor, Einfalt and Visual Slickedit for OS/2 and I even lost my copies of the first two, for some reason the modern Slickedit for Windows/Mac does not do it for me though ...

There is an extended, but not yet complete list of available editors for OS/2 here:

Storage / Re: NAS and OS/2?
« on: April 19, 2016, 04:25:23 am »
Any opinions on choice of disks for these systems?

Green drives for saving money?
Black drives for performance?
Red NAS drives for some other reason?

What makes a good drive for a NAS application?

Normal 3TB Toshiba drives 7200rpm drives, a number of online hosting companies have come up with data that suggests these are by far the most reliable drives on the market, the 1, 2 and 4 TB versions from the same company have a much better than average reliability, on par with the best WD drives and a class above Seagate.

According to the data 3TB Tosh have around 1+% failure rates over the course of two years constant use (online 24/7), other Tosh drives around 2+%, WD around 2 to 5% depending on model and Segate 5 to 11%, ditto.

As I run OS/2 and Win 2011 HS (for XP compatibility that is not available for newer Win servers) I have bought 2TB version as the OS/2 server cannot use anything bigger and the WHS needs quite a lot of manual work to use the 3TB ones so I have stuck with the 2TB ones, four in each server, one has developed a minor fault after about 14 months that the company swapped out for me even though it was out of warranty.

These replaced a host of drives bought in the period between 2009 and 2011, two Hitachi (Now Toshiba), two Samsung, two WD and about six Seagate drives, all the drives except one Hitachi drive developed some errors during their livetime, the Samsungs and the WD's could be re-used after a low-level format and have been re-purposed for my PC's, the Hitachi could not be fixed as WD (Who owned the Hitachi factory at the time) stopped supplying disk repair software that worked with that specific model but otherwise that drive only had surface errors so should have been recoverable, and it and all the Seagate drives have been thrown away. The only working Seagate drive left in the house is a 35 year old 506 .... so you can guess which drive manufacturer I am not recommending.
