- GENERAL SECTION
- ===============
-
- Q. I've found a problem with the WIN-OS/2 printer driver that I'm
- using with my printer?
- How do I get an updated version of the driver?
-
- A. The WIN-OS/2 drivers were not written by IBM, but are licensed for
- inclusion in OS/2. If you need a driver update IBM might be able to obtain
- it for you, but you'll get it much quicker if you contact the supplier
- directly.
-
- Q. How do I run WIN-OS/2 in real mode? Can I run WIN-OS/2 in 386
- enhanced mode?
-
- A. Type 'winos2 /r' from an OS/2 'DOS Full Screen' session, or put '/r' in
- the parameters held for an OS/2 shell object. WIN-OS/2 doesn't support
- enhanced mode and applications that require enhanced mode will not run.
-
- Q. Why won't ScanMan and FotoTouch run under WIN-OS/2?
-
- A. They both make a 4B interrupt call to create a DOS thread. This isn't
- currently supported.
-
- Logitech scanning hardware is normally used by WIN-OS/2 applications
- running in real mode. Note that Ansel (Fototouch's predecessor) will work
- in real mode.
-
- Q. I get DOS Error 5 when I try to run some of my Windows
- applications under WIN-OS/2? What do I do?
-
- A. Boot from OS/2 boot disk, insert disk 1 when prompted. When you get
- OS/2 Welcome screen press ESC. Insert disk 2 and type A:CHKDSK C: /F
- (FAT) or /F:3 (HPFS) where 'C:' is the drive OS/2 was installed to. Repeat
- CHKDSK until it runs without any errors.
-
- Q. How do I start multiple WIN-OS/2 applications from the same OS/2
- desktop icon?
-
- A. Drag a program object from the Templates folder. Set Program to '*',
- set Path to full path names separated by commas for programs that you
- want to start. See Master Help Index - WIN-OS/2 for more information.
- First program listed is incorrectly started twice.
-
- Q. I have the Canadian version of WordPerfect 5.1, how do I run
- FIXWP?
-
- A. FIXWP (see OS/2 readme) doesn't work for the Canadian version. Call
- WordPerfect and ask for interim release.
-
- Q. SHIFT-ESC doesn't seem to do anything under WIN-OS/2. This
- means certain programs (see Attachmate under Applications) can't be
- run. Is there a fix?
-
- A. A keyboard bypass option for SHIFT-ESC needs to be added to WIN-
- OS/2 and DOS settings for CUA (Common User Access) compatibility.
-
- Q. I Get FATAL ERROR 0X0401 trying to start a Windows
- application in a WIN-OS/2 session. What's the fix?
-
- A. This problem is caused by one or more of the drivers or font files listed
- in the WIN-OS/2 SYSTEM.INI or WIN.INI file being absent or not
- loading correctly. This can happen if the application migration/installation
- was incomplete/incorrect. Check device statements, or re-install
- application from WIN-OS/2 Full Screen.
-
- This error has also occurred on systems running in XGA or 8514 video
- mode when an application tries to use large fonts. It might be necessary to
- modify the WIN-OS/2 SYSTEM.INI file as follows; fonts.fon= xgasys.fon,
- fixedfon.fon= xgafix.fon, oemfonts.fon= xgaoem.fon.
-
- Q. I have an 8514 display and am having trouble using DDE with
- WIN-OS/2. What's the fix?
-
- A. If you have an 8514 display use DOS Settings to set
- VIDEO_8514A_XGA_IOTRAP to Off and
- VIDEO_SWITCH_NOTIFICATION to On.
-
- Q. Data I put in the OS/2 clipboard doesn't show up in the WIN-OS/2
- clipboard. What could be causing this?
-
- A. Because of the particular data format there may be a rendering problem
- that prevents the reception of the data from the WIN-OS/2 clipboard by the
- WIN-OS/2 application. A private data format used by one application
- could be unusable by another.
-
- Q. I'm using the EPSON.DRV WIN-OS/2 printer driver and I get
- duplicate form feeds, can I disable form feeds?
-
- A. The EPSON.DRV driver doesn't provide disable form feed or intelligent
- form feed options. If this causes you a problem you'll need to select another
- driver that works for your printer.
-
- Q. Every few pages my HP DeskJet 500C color printer prints a whole
- page condensed to slightly more than 'thumbnail' size. How can I fix
- this?
-
- A. You need to add [STATDLL] override=y to WIN-OS/2 WIN.INI file.
- Read the read.me file for your DeskJet printer. This file is located on the
- first of the DeskJet driver installation diskettes.
-
- Q. Sometimes when I switch sessions from the OS/2 Desktop back to
- WIN-OS/2 using the ALT-ESC option I find that I have no mouse
- pointer. Is this a known problem?
-
- A. This problem has been reported and logged. Simply repeat the ALT-
- ESC sequence to recover the pointer.

- MAIN SECTION
- ============
-
- Communications
-
- Q. I selected Setup - Options from WIN-OS/2 MAIN in WIN-OS/2 Full
- Screen and get a list of options including No Network Installed.
- Which option should I select?
-
- A. Unless you are using a DOS-based LAN requestor (rather than an
- OS/2 based LAN requestor) you should select option No Network Installed.
- The only other valid option listed is IBM PC LAN Program. All the
- other options were included in error and should be ignored. These
- options can be got rid of (by editing the SETUP.INF file in
- \OS2\MDOS\WINOS2\SYSTEM directory). In most cases, users should not
- try to do this.
-
- Q. What do I need to do to get Rumba for Windows working under WIN-OS/2?
-
- A. Rumba may have problems when running in the background due to some
- INT 28 handling done in DOS emulation. Currently it is best to run in
- VMBOOT session to avoid this problem.
-
- Q. Are there any reasons why my old Windows communcications packages
- won't run under WIN-OS/2?
-
- A. All WIN-OS/2 applications run in OS/2 VDMs (virtual DOS machines).
- VDMs support a maximum of 1000 interrupts per second and this causes
- problems for many communications packages running at higher baud rates.
- If you are having problems, try reducing the baud rate if this option
- is available for your application.
-
- Q. Does WIN-OS/2 include named pipe support? What applications
- require this?
-
- A. A fix which includes a correct implementation of named pipes is
- available. An integrated DOS kernel which includes this
- fix is expected to be available in the OS/2 service pack being
- prepared for release this fall.
-
- Some DOS and Windows applications use named pipes for access to
- Microsoft/Sybase SQL Servers. These applications also require that
- the file NETAPI.DLL for 'LAN Server' or 'LAN Manager' networks,
- or the equivalent for other networks, is accessible via the appropriate
- path statement.
