OS/2 Tips

We scan the Web, Usenet and the OS/2 mail lists looking for these gems. Have you run across an interesting bit of information about OS/2 recently? Please share it with all our readers. Send your tips to tips@os2voice.org. If you are interested in joining a particular OS/2 Mailing List, check out the VOICE Mailing List page for subscribing instructions for a large variety of existing Lists - http://www.os2voice.org/mailinglists.html.

Editor's note: these tips are from OS/2 users and in some cases can not be verified by myself. Please heed this as a warning that if you are not sure about something, don't do it.

September 22, 2000 - If you run into a problem installing RSJ CD Writer for OS/2 3.0x where you get a message "Please reboot your workstation before running the installation again." when you try to start the installation program, here is the answer from Sandra Seywald of RSJ Software GmbH:
Please check if there is reboot.rsj at the root directory of your harddisk. If yes, delete it please and try it again.

September 26, 2000 - Had a dirty shutdown and want to access the partition without completing a CHKDSK? Here's a tip from Christian Hennecke on the Warpdoctor mailing list:
No, this won't work. You won't be able to access the drive. Instead change the /AUTOCHECK parameter to /AuToChEcK. This makes HPFS ignore the dirty bit while still making the drive accessible.

September 28, 2000 - Stanislaw Kozlowski offered this tip for people having fixpak install problems due to the default C: partition being an alien format to OS/2. The tip was posted on comp.os.os2.bugs:
I have received a hint from Irv to use following set commands and that resolved the problem.
This makes service program to use drive d as temporary files space.
This makes service program to search only drive d as target for service. With these settings 4 GB FAT partitions are omitted from any operations that could result in a bug.

September 30, 2000 - Ever get a TRAP error and wonder what to do about it? Here is some advice from Roderick Klein on the eComStation egroup list to someone getting a TRAP with Ray Gwinn's beta SIO2K serial port driver. This post contained some information that I think anyone could use, so here it is in it's entirety:
Well thanks for the warning! But to be quite honest you don't really need to be afraid of running a beta device drivers. In past two or three years I have seen many traps on my system(ring 0). I did a BIT of testing for Sander van Leeuwen for his Ultrasound Card drivers. One of the projects I'm really testing for is the generic WIN/OS2 driver from John Gow (home.wanadoo.nl/~rwklein) Its quite a complex driver and I have seen many, many traps on my system. What I did on my system was turn of lazy write. And switched to HPFS for 100%, since then I have not lost one single file with beta device drivers.

If you ever get a trap, look at the screen and don't just hit the reset button! In some cases it may be worth looking into it! When you a trap in ring 0 (black screen) look at the CSLIM= value on the screen, if its not equal to ffffffff write down the last four digits. Hit the reset button and download this file (or on another machine) and read the simple instructions!


You can maybe find the device driver that is the trouble maker!

On the point of the GWINN serial drivers, if you get a TRAP, do something with it! Most projects run dead because developers don't get enough or none feedback! They test there driver and they think about how the device driver should function! Writing a device driver is not that easy!

So what must you do ? There you are, you get a trap and the screen says "Write down all information and contact bla bla bla". Writing down all the registry information ? I did it a few times.... But you can cut and paste a trap screen, how ?

Get an empty diskette, press CTRL ALT NUM LOCK (twice) (or CTRL ALT F10 for a laptop), the diskette will be erased! Insert disk and wait! No you don't have to make a complete memory dump! After the first floppy disk, hit the reboot button! If you have a large HDD with HPFS go and have a cop of coffee (got eCS with JFS, sit back and relax!). Open the file on the diskette in a binary viewer like e.exe. You need to search for a moment but somewhere 1/3 along the way you should find the same trap screen! Now you can copy paste! (Instead of writing down or typing over!)

Now if you just installed the GWINN drivers and rebooted and get the trap, changes are very big that it are the GWINN drivers (since there BETA!). So lets help out the developer! Do what I described above, send the trap information and what you where doing (dialing out with the modem ?). And maybe a short list of what is in your system and especially what kind of serial equipment you have!

I think he will find the feedback quite useful!

October 1, 2000 - On comp.os.os2.misc, Lorne Sunley offered the following advise for those using Partition Magic to move/expand FAT partitions and then encounter problems with OS/2:
Find the PTEDIT program on the partition magic CD or on their web site and change the "type" of the extended partition back to '05" from the '0F' that PM changed it to when you moved the partitions around.

Type '0F' extended partitions are a "Window-ism" that is not understood by OS/2 and PM v5 like all good "Microsoft-centric" software converts partition types without telling you.

October 1, 2000 - Java 1.3 is starting to get around, even though it's still a Preview version as of this writing, and you can only obtain it with a Software Choice subscription, or by purchasing eComStation. Seems there is at least one problem with it where it gives an error message 'Could not find file AWT.dll'. here is the solution as detailed by Maximilian Stempfhuber on comp.os.os2.beta:
don't know whether an earlier post got through: the problem was the entry 'set java_home=c:\java11' in my config sys. this seems to irritate at least fonts.dll. all other modules use the registry entry of java_home. setting it to c:\java13\jre in config.sys solved the problem. folks at ibm said it was too late to change the binaries but it may be noted in the readme.

October 3, 2000 - Bob Marks reported success with his Orb drive on the OS/2 Hardware list:
I finally got my system back to working condition with FP14 so far so good. I now have the ORB working very nicely as a mater of fact I split one disk into two partitions and connections now shows two removable drives. The trick is to use fdisk on the disk first and set the primary partition to an EVEN size. Then fdisk will leave the remainder for the second partition. This prevents Fdisk from stick a small unnamed partition at the beginning of the disk which will cause problems later on.

October 4, 2000 - Though I've never needed to know the MAC address of any of my network cards, here is a tip on obtaining that bit of information should you ever need it, courtesy of Bob Eager on comp.os.os2.misc:
netstat -n
arp -a for other systems on the network

October 9, 2000 - Have you ever needed an easy way to get rid of Red-eye effect in a photographic image? Here's a tip from none other then me :-)
I used Embellish for this. It was very easy to remove Red-eye. I just magnified the image view by 5X, selected a a circle area around the Iris, then selected Color->Adjust and decreased the Red by about -90, and bumped up the blue a bit, then repeated the same for the other eye.

Though unfortunately abandoned and unsupported now, a fully functional version of Embellish is still available at http://www.dadaware.com/ftp/embos2.zip

October 10, 2000 - Ever have some INI entries that weren't deleteable by Checkini? Her is a tip from Dave on the OS/2 List that might help:
Funny, I just figured out how to get rid of handles like this (including am2). Just invoke F:\UTILS\WPTOOLS>checkini.exe /c /h
note the /h

/H - Only do the check on PM_Workplace:Handles0/1. Please note that
this could cause UNKNOWN OBJECT errors in other tests when
CHECKINI is run again. This is because handles that CHECKINI
deletes might be in use in other keys.

October 10, 2000 - If you have two D-Link DFE-530TX+ network adapters in the same machine, here's a tip from Dan Casey on the OS/2 Hardware list on getting them identified:
I have 2 DFE-530TX+ cards (using Realtek driver).

One instance of the driver loaded in config.sys.

Manually edited the PROTOCOL.INI file ... relevant parts posted below.

MPTS did part of the job, but failed to include the BUSNO and DEVICENO entries. The DIAG software (run in DOS VDM) reported these values, and I edited the INI file accordingly.


netbeui_nif = netbeui.nif
tcpip_nif = tcpip.nif
RTL8139_nif = rtl8139.nif
RTL8139_nif2 = rtl8139.nif


DriverName = RTSND$

DriverName = RTSND2$

October 11, 2000 - ShyGuy offered the following tip on the ecomstation.support.misc news group for anyone looking for a quick way to minimize all windows to get to the desktop:
If I click on "Switch to another Application" in the Warpcenter I get desktop listed. Clicking on desktop minimizes all the open windows.

October 11, 2000 -Mike Reichel on the xworkplace-user egroup list offers this workaround for the Extended Shutdown hang in Xworkplace 0.9.5 when Warpcenter is running:
I use the shutdown folder with a additional program to close the warpcenter. Than the shutdown works.

You can test: (v1.00) PGMCNTRL - VIO program
PGMCNTRL allows you to perform actions like kill and query and window functions
like minimize, maximize, restore and hide on _every_ process in the system.
Identify the process by pid (decimal and hex) or by the simple or fully qualified
exename. FREEWARE ! Author: C.Langanke@TeamOS2.DE

Put a program object with "pgmcntrl WarpCenter /close" and "start minimized" and "close after completed" in the XShutdown folder and the WarpCenter closes. (If there is no WarpCenter active, than nothing happens. )

October 13, 2000 - Here's a tip on USB port assignment from William L. Hartzell on the comp.os.os2.comm:
Know that you can assign an alias to the USB port by using /N:COMx at the end of the USBCOM driver line. Thus it becomes usable with software that does not know about USB ports. You will need one driver line per modem.

October 16, 2000 - I stay away from gtar archive files, but if you have to deal with them, maybe this tip from Illya Vaes on the ecomstation.support.misc news group will be helpful:
If you unzip to standard output and feed that to tar, you don't need to create the huge tar-file to extract the files: gzip -d -c file.tar.gz | tar xvf - (this will create the files/directories in/below the current directory)

October 17, 2000 - According to Martin R. Hadam on the OS/2 List, there are new Postscript drivers out which fix a bug "instead of a page you go a stamp-like image on the lower left corner) with printing from pmmail, epm and a host of other software":
Just downloaded and tested using PMMAIL: the new PS driver v30.728 ..... a MUST for all ps printers

File date is Oct 10th.

October 20, 2000 - Now that we have a German version of the newsletter, I've been in need of translation help more so then ever before. Here's a tip from Marcus on the ecomstation egroups list:
Systransoft has a better and less used translation page. It's their specialty.
