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 editor@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.

August 19, 2000 - Running out of disk space? Maybe it's time to do some house cleaning. here's a tip from Buddy Donnelly in comp.os.os2.apps:
and while you're deleting accumulated temp files, don't forget to look in \MMOS2\INETTEMP.
And here is some more on cleaning up from Marvin L Jones:
This snippet from my STARTUP.CMD:
@del \tcpip\tmp\*.gif
@echo y|del F:\netscape\cache\*
@del F:\netscape\cookies.txt
@copy D:\netscape\users\jonz\cookies.sav D:\netscape\users\jonz\cookies.txt
@del D:\netscape\users\jonz\netscape.hst
@echo y|del D:\netscape\users\jonz\cache\*

The D:\NETSCAPE is 4.61 , the F:\NETSCAPE is 2.02 As you can see, I 'manage' my own cookies. Maybe this can give you some ideas.

August 22, 2000 - Here's some suggestions on analysing TRAP problems from Roderick Klein on the eComStation@egroups.com mail list:
A general remark for everyboby who gets a trap!

Don't just hit the reset button and hope it won't come back, try and trace a trap! One of the most helpfull hints is this! When a trap occurs write down the CSLIM value. Is it FFFFFFFF? never mind then just hit reset... Is CLSIM != FFFFFFFF? then you can be lucky!

After a reboot (if possible) go onto the internet and download this tool:

ftp://hobbes.nmsu.edu/pub/os2/util/disk/exeinfo.zip (only 22kB).

This is the manual:

Exeinfo searches your partitions for executable code (device drivers, file systems, EXEs, DLLs) that matches some criteria. To locate the module that caused a trap, write down the CSLIM value that is reported. Then run "exeinfo -f -lxxxx c:\*.*" where xxxx is the CSLIM value and C: should be replaced by each driver from which code may have been loaded.

If, for example, you get CSLIM=0000f113 and all your code is loaded from the D drive because you have multiboot, type

exeinfo -f -lf113 d:\*.*

Another hint for fixpak 13 users and higher, got a Teles ISDN card! Rem out this line:
That driver is not that good with the WSeB kernel..... it's not a fault in the kernel; the device driver has been written badly....

Also when you have an application that causes a trap. Its useless to uninstall the app and reinstall. All apps are ring 3 code (they don't run on kernel level!) Usually its a sound driver or video driver. Switch to standard VGA or change resolution. Turn off sound, this way you can in many cases locate the problem!

August 21, 2000 - Do you have a Lynksys Etherfast 10/100 LAN Network card that has problems working under OS/2? Kevin offered this help on comp.os.os2.networking.misc:
Several past messages concerned this card and the problems it had working under OS/2 (it didn't work with the supplied drivers). I found that under Linux my card (which has version 4.1 printed on it) was identified as an ADMtek Centaur series. After a bit of hunting I got to the ADMtek site (http://www.admtek.com.tw). Under products, Centaur series, AN 983 chip you can find a bunch of driver diskettes. Download the one for fast ethernet v 1.06 (a standard zip file). Unzip it (creates directory fastnic.106 with various subdirectories. NDIS\OS2 is the one you want) and point the MTPS adapter card update (or "other adapters...") to the ....\NDIS\OS2 subdirectory. The card will then appear in the list as a "PCI 10/100 fast ..."). When the drivers were copied over to the \IBMCOM directory, the nif file (fastnic.nif) in \IBMCOM\MACS had to be edited to show the correct path (\IBMCOM\MACS instead of \NDIS\OS2). Follow the rest of the MTPS instructions abd reboot. The new driver should now find the card and you're set

August 23, 2000 - Trying to get a USB modem working under OS/2? Here is a tip from Gregory Urban on the TEAMOS2HELP-L mail list:
I've had some success with the 3Com USB modem. My current system has no physical COM ports assigned. I am using a SCM internal 2-bay PCMCIA unit so that I can access CompactFlash cards from a digital camera via PCMCIA adapter, but I do not use a PCMCIA modem or network card. I do have a 3Com ISA network adapter though.

Now...some tips. There is an undocumented switch in the USBCOM driver to specify which port it uses. I've currently got it assigned to COM1....here is the relevent info from my CONFIG.SYS:

REM ----------------------------
REM ----------------------------

Note that I do not currently have COM.SYS/VCOM.SYS or the SIO drivers installed. If you need to run the USBCOM port on any other port than COM1 you have to specify it. Say you want COM3 then the switch would be /N:COM3.

Problem is that if you are using more COM ports than just the USBCOM port you can run into conflicts. The Warp included COM.SYS automatically claims ports 1 through 4. To get around this I used the SIO drivers and specified which ports I needed. Check the docs that come with SIO to see how to specify specific COM ports. At one time I had COM1 and 2 through SIO and had the USBCOM port set to COM3 and it all worked. I did away with all that though.

Best suggestion I have at the moment is simplify things and experiment. Try getting the USBCOM port to work. If you need the other physical COM ports, use SIO and specify COM3 for the USBCOM port.

August 28, 2000 - People who have applied the TCP/IP 4.3 update from Software Choice have been encountering a TRAPe error when using PPP dialup connections. Bjarne Jensen of FX Communications, the developer of Injoy Dialer as well as other OS/2 connectivity products, offered this work-around on the Injoy mail list, for the problem until IBM can fix it:
People with this problem should try to set the netmask in the InJoy Dialer to ... I tried and it seems to solve ALL problems, but would like to hear more from others (asap).

August 28, 2000 - It seems some setup programs can not install on LAN-disk - it says that 'cannot create folder' or 'not enough disk space' when in fact there is plenty of disk space. Here's a solution for the problem from Joachim Benjamins on the Odin Users mail list:
There is an option in the \IBMLAN\IBMLAN.INI (of OS/2 Warp 3 Connect or higher at least) where you can set the amount of reported free space to Windows requesters. It is bit 35 of wrkheuristics:

; 35 free disk space reported to DOS and Windows applications
; 0 = return true value (default)
; 1 = return a value less than two gigabytes

Perhaps it can help you here?

August 29, 2000 - I was doing a search on Deja News for something network related and ran into this old but still useful tip posted in May from Gene on comp.os.os2.networking.misc. If you are having problems getting your peer connections to start on bootup, try creating a version of Gene's batch file to start them:
Here's a copy of a batch file I call netstart.cmd that was started from startup.cmd on our machines before I applied the fixes to ip08412 here:

-------------------------------------------------------------CUT HERE
@echo off
net start requester
Rem Batch file to setup network connections from \\MACHIN1
Rem -----------------------------------------------------------------
-------------------------------------------------------------CUT HERE

You will, of course, have to provide your own connection info. Type
'help net' at a command prompt to get more info on the 'net' command.
To start this from startup.cmd I used:

'start "Network Startup" /win /min e:\bin\netstart.cmd >nul'

September 11, 2000 - Many OS/2 fixepacks and the installation files come in special "bundle" files. If you ever wondered how to access these bundles directly, here's some help from John Martin on the eComStation mail list:
UNPACK bundle .
unpacks all files to the current directory (Note the "." at the end)

shows the files (does not unpack)

UNPACK bundle
puts the files in the correct directories
(dont do this on your boot drive unless you are sure)

And Duane Chamblee added this warning:
Careful with the IBM bundle files. These contain root paths (/OS2/...)
and will try to create file from the root of your current directory

September 12, 2000 - Carl Brown ran into a problem with win-OS/2 support while installing a driver for the Matrox G400, then asked for help on the OS2-L. Here is Carl's own answer to his problem:
Then I remembered the procedure I had to use the last time Winos2 died under the ELSA card. That one worked.

1)Run Selective Uninstall, remove DOS & Windows support.
2)Run Selective install, install VGA driver.
3)Reboot. Run checkini /C /Y:2
4)Reinstall DOS & Windows support.
5)Install new video drivers.

The odd thing about the "Error loading DISPLAY.DRV" is that at no point during the above procedure was there a file named display.drv on the system.

September 14, 2000 - For anyone interested in finding a Free Web provider that will work with OS/2, here is a tip from Thomas Mueller oncomp.os.os2.networking.tcp-ip:
I formerly was with FreeWWWeb, where you could dial in with your own software, then FreeWWWeb was taken over by Juno. Now there is One Nation Online (http://www.1nol.com/central). Some people on the Arachne (http://arachne.cz) e-mailing list use 1nol from DOS. What turned me away was lack of local access in my area, not a single phone number in the state of KY, though there were 25 in RI.

September 16, 2000 - Ever get stuck at a website that won't let you use the Back button to get back to where you had been? Here's a tip for Netscape Communicator users from Mohit Sindhwani on OS2-L:
You might of course, choose to click on the Back button, keep it pressed (or use right click) to see the options pop up and select the one that you know didn't forward you here.

September 18, 2000 - We've had a past tip on using ARCINST to refresh your systems Initial Desktop Archive to use your current settings. Here is some more info about ARCINST that we didn't realize from Steven Levine on the OS2-L:
Arcinst refreshes the desktop backup data structures.
So if you are having a problem with getting your system to create desktop archives, try running ARCINST and see if it fixes the problem. Of course it will also update your baseline archive, so keep that in mind.
