Applications / Re: Shadow/Shortcuts - Desktop Structure
« on: 2011.04.02, 17:06:57 »

  Hi, Martin!

Possible, another way (again from my point of view) will be to include the folder structure inside the "Programs" folder and have the "Installed Software" folder with all the mess for installed applications.
Check the screenshots as an example:

  This is just my approach. I also have a "Temp" directory on the desktop and a Download folder there (in fact, they are shadows so the "Archive Desktop" do not eat all my harddisk with useless backups of unimportant files).

  My suggestion would be some "themes" when one is installing eComStation. Something like the user can select:

  "1. Clean Desktop"  (Only Applications/Programs folder, everything else there)
  "2. Basic Desktop" (Only Applications/Programs, Network Neighborhood and System folders)
  "3. Full Blown Cluttered Hell Desktop" (The way eCS orgnizes the desktop today)

   And... for install Options:

   "1. Place software on programs folder."
   "2. Organize software into categories on programs folder."
   "3. Same as 1, plus place exe icon shadows on Applications folder."
   "4. Same as 2, plus place exe icon shadows on Applications folder."
   "5. Same as 1, plus place exe icon shadows organized in categories on Applications folder."
   "6. Same as 2, plus place exe icon shadows organized in categories on Applications folder."

   These options will not *solve* the problem, but will provide options that will easy the pain for everyone (ie.: keep the desktop/applications icon maintenance as easy as possible for every user).

   The problem is: basic desktop can be configured by Serenity on eCS install. The Install Options can be respected by the installer... but after that, it would require modifications on WarpIn and WPI packages (I think)... which means everything done before would not respect our wishes and keep adding annoying folder icons on our clean desktops. :P

i hope you all saw the announcement about OpenJDK RC2. There is also a new Odin. So please test Flash again with this new Odin. It's possible it works a lot better.
But be aware the SMP problems are still there. We are right now looking into them.

  This machine is non-SMP and Flash10 works somewhat fine. Anyway, every now and then I find some website where the mouse clicks are just ignored by eCS Flash 10 (they will work nice on Windows). Should I raise a ticket or better live it alone until you guys fix the SMP thing? :)

USB / Re: USB to Parallel Bridge
« on: 2011.04.02, 16:03:27 »
My experience has been the opposite to you - AMD boards are the only ones that I've been able to get to work well with OS/2 WSeB SMP.  In fact just yesterday a client brought his new Acer computer to have OS/2 installed - It was one of the fastest installs I've done, OK, only 2 core and 2 GB ram with 500 BG hard disk.

  Ah, well, my experience with SMP is on eCS and ACPI... I'll forward this info to a friend who has 3 or 4 AMD multicore computers which simply do not run OS/2/eCS (Opterons and newer processors).

You have to remember Rob is in the US where every thing for computers is cheep.  I was looking for one of the HP etherjet adapters for my 4L but found them expensive here in Europe as well - I finished up getting a print server from our local internet market for 35 euro.

  You gave me a nice idea, Ivan. A print server may be the way to go! :)
  Any remarks? My HP CL1515n is being used with the help of LPD, mapped on port LPT2... it should be nice to acquire a print server that works the same way. :)

BTW your PM Download Center is still in use on all my machines - thanks.

   Cool! :) From time to time I think I should rewrite the whole thing... But had not found the time yet.
   There are several other projects in the pipeline (SDL MSX Emulator almost ready, ZX Spectrum
emulator - both with complete sound, p7zip, a new version of Squeak/2, an utility to use Floppy
Driver Emulators (using SD-Cards) and a utility to generate/extract DSK files)...  :P

Daniel, you did set up the printer to use a USB port and not a parallel one because with that adapter the printer becomes a USB printer as far as OS/2 is concerned.

  Yup! But spooler acts as if the printer is offline (even though the USB port says it is online).

  Hi Paul,

I just bought the same processor, but I chose an Intel P67 based motherboard.  I have eCS 2 running, but currently not in a satisfactory manner.
Onboard LAN (Realtek R8111c) is not (yet) supported by the new eCS Realtek driver - although it is supported in the latest linux source, so it should be trivial to add support.

  The board I bought (this one: ) seems to use a IntelĀ® 82579V based ethernet, I hope it can be supported soon by eCS drivers (some flavors of 8257x are supported).

Sound is recognised by Uniaud 2.1.x but not Uniaud 1.9.x (due to higher ALSA version in 2.1.x)

This one has ALC892. Dunno if it'll work, probably not.

SATA controller only works in generic mode until Danis506 is updated.
Widescreen activator doesn't recognise the CPU bridge but I'm in conversation with Robert Lalla on that issue and hope to have that resolved soon.
High IRQ loads are common - I believe this is due to system MTRR not being set correctly.  Unfortunately whilst Lars Erdmann has a utility to set MTRR's - it's currently failing here with:
GRADD.SYS returns error 65330 in IOCTL call GRADDPDD_QUERYMTRR.Cannot query MTRRs.
and Lars is very busy right now.
Once all the above is resolved it should be a nice system :)

  Well, at least there is some chance of improvement in the future. :)

  I selected H67 board for two reasons: 3x common PCI slots, which allows me to bring some of my old (and eCS supported hardware) like SBLive 5.1 (if onboard sound do not work), BT video capture board and PCI SCSI adapter for my Vista S6E Scanner. I'll have a problem if network AND sound do not work... (so, I really hope there is a way to use the onboard ethernet... hehehe).

  Thanks for the feedback. I tried to look at hardware database on OS/, but I found it is not very friendly if you do not want to read ALL the reports... some search filters would be great there.  :)

Some news. I don't know how and why, but trying several times (plug and unplug) made eComStation recognize a new USB Printer Port, called "Prolific_IEEE_1284_Cont_1". Is it something (eComStation even created a Printer Icon "automagically"), which was reported to be "ONLINE" on the port propertied...

But no print when I send something to it (even selecting the correct printer driver for the object). The print job stays on the spooler forever. On the port properties I have found several config options for different delays... I'll do some more tests later.
For information, this is the bridge I bought: It uses a common controller ( ) and there is a somewhat detailed datasheet for it:

Comments, Suggestions & Questions / Update Password?
« on: 2011.04.02, 05:06:39 »

  Is there some problem with the password change on "Profile" section?
  If I change my password for a new one... I cannot login anymore, be
it with the old one or with the new one. The only solution is selecting
"Lost my password" and receive a random generated password, which
I will forget in the next second and so... every time I want to access these
boards I have to generate a new one.

   Any clues?

I have yet to find a USB to parallel bridge that works, but that does not mean they don't exist.
Another solution would be to pick up (they're really cheap) one of the HP etherjet adapters and run it via the network, which should work fine for the older HP machines (there are actually OS/2 drivers for them).

  Hi Rob,

  Unfortunately, these adapters are not "that" easy to find here, in Brazil.
And they are not cheap for sure (in Brazil)... but, if it is the only way and
I had already lost 25 bucks on this damn useless bridge... :P

  Thanks anyway.

For your USB/parallel unit to work you need the parallel equivalent of USBCOM.SYS  - USBPAR.SYS?????

  Somewhere I've read USBPRT should work for USB/Parallel bridges (this bridge
only work with printers, even on Windows)... That's why I've asked.

In some ways it is unfortunate you went the Intel route as there are several motherboards for the AMD processors that have both parallel and serial ports.  I've recently been through the process of building a couple of machines that required both parallel and serial ports.  Both machines have AMD multi core processors - one 4 core, the other 6 core, also both have 4 GB ram, could go to 16, because that is more than enough for their intended purpose.

   Well, I went to Intel route for one single reason: every Intel motherboard I
have found is able to run eComStation in SMP mode... not quite the same
with MB for AMD processors (in fact, I have not found one yet). I know there
are boards which will work ok... but I was not in the mood for gambling.
(And it is not that easy to "select whatever board you want" in Brazil...
most motherboards simply cannot be found in the market).
   I am telling this because I am not a big fan of Intel processors and
chipsets - the computer where I am writing this is an ancient Athlon XP 2600+
on a ASUS board with nVidia chipset... which is still working nice. :)
It will become my backup hardware.

   I am trying just to take a safer route... which doesn't mean I'll be successful.
Heheheh... Maybe the new machine not even boots eComStation. :?

Rob's idea of the HP etherjet adapter may be the only way that you will be able to run your printer, although if you have a NAS box with a USB printer port you might be able to use your adapter with that but the setup could be a pain.

  Hummm... Well, I will try to find one. I have searched for a LaserJet 5 ethernet
adapter, but no luck so far. They are not common in Brazil, and whenever
someone has one to sell, it's not for less than 200 dollars.

  Anyway, my other printer, HP CP1515n, works very well through the network.
It would be nice do the same with HP LaserJet 5, too. :)

USB / USB to Parallel Bridge
« on: 2011.04.02, 00:04:52 »
Hello guys...
I am buying a new machine (brand new i7 2600 processor, 8GB of RAM, intel H67 based motherboard) and I hope to run eComStation 2 in this machine. It will be here by april 20, so I am only guessing if it will work.
In the mean time, since new motherboards do not offer any parallel ports (and I have an ancient LaserJet 5 which I do not want to let go) I started looking for alternative solutions... and I have just found a so-called "USB to Parallel Bridge". It is basically a cable, which connects to the parallel centronics connector at the printer and then to an USB port on the computer.
On Windows XP I just plugged it and it recognized the device... but on eCS... well, it seems to be detected... BUT when I install an USB port to the printer driver it says "there is no USB printers connected".

Anyone has any kind of experience with this kind of peripheral?

Thanks in advance!

Hardware / Missing WordPro Equation Characters when printing
« on: 2011.01.05, 19:20:28 »
  Since many many years ago I am fighting with an annoying problem
with WordPro versus PostScript printing. Whenever I try to print a
WordPro document which uses equations in PostScript format (so
I can compile a PDF), the result is a PS/PDF with missing equation
elements ( radical signs, fraction bars, exponents etc. ). This is
VERY annoying and now is turning into a real problem, since I need
a PDF version of my thesis (university request).

  I am using "Apple Color Laser Writer 12/600", found on the
latest version of "PSCRIPT.DRV". Tried other drivers but no
luck with any of them. Searching on Google I've noticed some
people had this problem using eCUPS (which I have installed
here). I downloaded the latest fix suggested on the page
( )
and installed it and then created a new printer object with the
"Generic PostScript Printer" found on eCUPS.drv, but the
problem remains. I have also tried other eCUPS drivers
such as "HP Color Inkjet Printer CP1700", but again, no

   Anyone knows how can I solve this annoying problem (besides
migrating to OpenOffice or MS Word, *grin*)?

   Thanks in advance!

PS: I tried both Acrobat Distiller 5.0 e ePDF to compile .PS into
.PDF... and both presented the very same problem... this is why
I believe the problem is on the .PS generated by the driver.
PS2: *** CORRECTION *** printing directly to a non-PS printer
(such as HP LaserJet 4) is ALSO generating erratic results. Maybe
the problem is in Lotus SmartSuite? ARGH!

*** CORRECTION 2 ***
Disabling "use downloaded fonts / use device fonts" and when printing
just some pages directly to HP LaserJet 4 it prints correctly. It seems a
problem with memory management (?) inside the printing driver. The
behavior is really erratic. I have tried these instructions:
but was not able to reproduce the results.
Anyway, it seems now only fraction lines are missing (!!)

Even I am a fanatic OS/2 user, I do not want to slipped other people to. There is alternatives, free of charge, wich isn't beautiful like /2, but work with any hardwer, and work with much less problems and faster.  :'(

  Cyber, I believe every single OS/2 user is concerned about the future and how
to keep things going. Of course there are many obstacles to be beaten, but the
only way to get over them is one by one.
  While basic hardware support is gold, Serenity and other individuals have been
working on it for years... and more advancements are in the pipeline.
   That doesn't mean we do not need support for not-so-essential-technologies.
OGL support seems cosmetic, only for bells and whistles... but it's not. When
saying this will be just one more piece of not used library, keep in mind that SDL
should have support for OpenGL; it has not due to limitations on the available
alternatives at this moment. With a working and up-to-date SDL GL support,
several games would be available, and that would be even better if it is hardware

    If it is difficult to bring new users to eCS-OS/2, it can be even more difficult to
keep them using it when we do not even have the ability to run 3D applications or
even present him with a nice-looking operating system. Most advanced users
(not the lemming type) believe OS/2 is very advanced in the way it works and
in the way we use it, but they also think it looks like outdated and the support for
new technologies is non-existent. Something has to be done in this arena.

    Besides all I said previously, there is a new generation of monitors capable
of 3D which would never be reliably supported without a real 3D rendering stack.

    This is the reason I believe this effort is worth the community support. I do not
think it is a simple project but... even if the project fail, the effort shows at least
that our community will not fall without a fight. :)

In an earlier post, someone refurred to OpenGL on OS/2 as GL/2. For a lack of a better name, I think I'll just stick with that name.

  Great name, indeed. :)
  Man, I believe most members on OS/2 community are now crossing their fingers, hoping for any development on this arena. There were many developments on important areas such as ACPI, QT, UniAud, Panorama, Samba, Flash and even Java; these are great to keep us alive, up to date... and adding real OpenGL stuff to this set of improvements will be awesome because we've been waiting for this support for almost 15 years!

   My best wishes and my kindest regards!

Trying the release I get:
Error loading: <%path%>\jre\bin\client\jvm.dll

Anything obvious missing?

  I had this kind of problem before I did two things:

1) Installed new Odin
2) Rebooted
3) Defined the environment as following:

set PATH=c:\programs\java160\bin;c:\odin\system32;%PATH%
set BEGINLIBPATH=c:\programs\java160\bin;c:\odin\system32;%BEGINLIBPATH%


to clarify, it's 1.6.0-b19 not b13

  Hi Silvan,

  After some minor changes and setting CLASSPATH=.; OpenJDK / Java 1.6 is now working successfully. I built some simple command line programs without problems. Is there any kind of specific tests I could perform to help you on the development?

  Thanks for the marvelous work!
