Troubleshooting IBM Thinkpad Hardware Setup Problems
If you should experience problems setting up PCMCIA Cards or ISA Adapters (in
the docking station), please follow the procedures listed below:
Troubleshooting IBM Thinkpad Hardware Setup Problems
If you should experience problems setting up PCMCIA Cards or ISA Adapters (in
the docking station), please follow the procedures listed below:
(1) Please ensure that your ThinkPad is using the latest BIOS release for that
system. Later BIOS releases correct problems that users have experienced with
the earlier releases. Refer to the ThinkPad BIOS section to determine if you
need to update your system's BIOS.
(2) Make sure that your software drivers are at the correct release level and
are setup properly. Refer to the ThinkPad PCMCIA Drivers section to see if you
need to update your system's PCMCIA device drivers. If you are using Point
Enablers, please ensure that they are at the latest release level.
(3) Determine if any upper memory conflicts exist between the areas claimed by
ThinkPad BIOS, Card & Socket Services, Point Enablers, the SCSI Adapter found
in IBM Docking Stations, and any ISA Adapters installed in the docking station.
Refer to the ThinkPad Memory Map and the ThinkPad Dock I & Dock II Memory Map
sections.
The Device Driver DICRMU01.SYS /MA=C800-CFFF (DOS PCMCIA Resource Map Utility)
sets the upper memory addresses used by Card & Socket Services. The /MA
parameter tells Card Services what locations in upper memory can be used by
PCMCIA cards or Card Services, and must match or be a subset of an excluded
memory range on the EMM386 line of CONFIG.SYS.
(4) Microsoft Windows can overwrite the upper memory address used by Card &
Socket Services. To prevent this, add an EmmExclude=XXXX-XXXX statement to the
[386 Enh] section of SYSTEM.INI (Where XXXX-XXXX is the same as the memory
region as used in the /MA parameter for the DICRMU01.SYS driver). If you are
using point enablers, be sure to exclude any upper memory used by the enabler
by adding an EmmExclude statement to SYSTEM.INI.
(5) Make sure that no interrupt conflicts exist between ThinkPad devices,
PCMCIA Cards, the SCSI Adapter found in the IBM Docking Stations, and any ISA
Adapters installed in the docking station. Refer to the ThinkPad Interrupt
Assignments section to view the default interrupt assignments.
Please note that the ThinkPad System Setup Utility allows you to view and
change interrupt assignments for many internal devices.
The Resource Map Utility (DOS - DICRMU01.SYS, OS/2 - ICRMU01.SYS) can
automatically detect many IRQs already in use, but may not detect all. Try
excluding the IRQ of the onboard SCSI and any ISA Adapters in the Docking
Station by adding the /IX=xx parameter to the Resource Map Utility (where xx is
the IRQ number to exclude). Multiple IRQs may be specified by separating with
a comma.
(6) Ensure that no DMA conflicts exist between internal ThinkPad devices and
any ISA Adapters installed in the docking station. Please refer to the
ThinkPad DMA Assignments section.
(7) Some ISA Adapters in the IBM DOCK I and DOCK II may require the ISA Adapter
Timing Fix. Please download YPTF012.EXE from the IBM BBS.
Troubleshooting IBM Thinkpad MWAVE Modem Problems
If you should experience problems with the MWAVE DSP Modem, please follow the
procedures listed below:
(1) If you experience a NO DIALTONE Error, reseat the telephone DAA Module.
Disconnect the phone line from the ThinkPad and leave the hatch door open.
Lift open the keyboard. Slide the blue switch to the left. This unlocks the
DAA Module for removal. From the left side of the ThinkPad, pull the black DAA
Module away from the ThinkPad. Firmly press the DAA Module back into the
ThinkPad to reseat it. Lock the DAA Module in place by sliding the blue switch
all the way to the right.
(2) Please ensure that your ThinkPad is using IBM ThinkPad MWAVE software
Version 2.0 (or later). Please review the Drivers section of this document for
the current MWAVE code.
(3) Review the communications settings for your modem software:
To Set: Select highest ranking available setting:
Modem type 1. Mwave modem
2. Generic Hayes-type modem
3. User-defined modem
4. Hayes SmartModem 2400
5. Hayes modem
6. Hayes compatible modem
7. Other (Note: If you select a modem of type "Other," you
must include the proper modem initialization string. For
most applications, the initialization string "AT&F" will
work. See the MWAVE Modem on-line help for more
information.)
Baud Rate 57,600 Kbps, or the maximum setting offered by your
communications software.
COM Port COM 2
To determine if communications software configuration is a problem, test the
modem using the Windows Terminal program (in the Accessories Folder). Run
Terminal. Select COM2. Select Settings, then Modem Commands and make sure
that Hayes is selected, then select OK. Next, type atdt at the command line
and hit Enter. If you receive a dialtone, then you probably have a software
configuration problem with your specific modem software. If you do not receive
a dialtone, continue with next step.
(4) Double click on the ThinkPad Setup Icon. The double click on the System
Information Icon. Review the IRQ settings to ensure that (a) the DSP device is
active (default is IRQ10); (b) the modem device is active (default is IRQ3);
and (c) no other devices conflict with the DSP and Modem IRQs. Next, review
the DMA settings to ensure that the DSP device is active (default DMA7) and
that no other devices conflict with the DSP device.
(5) Within the ThinkPad Setup Icon or Folder, double click on the Serial Icon.
Please ensure that Serial Ports A & B are disabled or do not conflict with the
MWAVE Modem.
(6) Open MWAVE ThinkPad Icon or Folder. Double click on the Modem icon. This
enables the MWAVE Modem. This program can be minimized. However, it must
remain running while using the MWAVE Modem (please note that this item does not
apply to MWAVE 2.0 for Windows or MWAVE 2.1 for Windoes 95).
(7) Lotus Notes users should download LOTMWAVE.EXE from the IBM BBS. This file
provides Lotus Notes with a MWAVE modem definition.
(8) Microsoft Mail users should download MSMMWAVE.EXE from the IBM BBS. This
file provides Microsoft Mail with a MWAVE modem definition.
(9) The MWAVE Device is initialized each time Microsoft Windows is started.
This means that a communications session started in DOS would be terminated
when Windows is started. Users who need to start the MWAVE Modem in DOS and
keep it running while starting Microsoft Windows should use MWAVE Version 1.1
and download MWDOSMOD.EXE. A fix for MWAVE Version 2 should be available
shortly.
Installing Windows 95 on the ThinkPad 755Ce, 755Cse, 755CD, 755CDV, 755CV, &
755CX
(1) For complete Windows 95 directions, please download TPWIN95.EXE from the
IBM BBS.
(2) If your ThinkPad is still running the original IBM software preload,
download WIN95SET.EXE as well. This diskette will prepare an IBM ThinkPad
loaded with the IBM software preload for Windows 95. The diskette will check
the BIOS level of the system, stop the ThinkPad Welcome Screen from being
displayed automatically, and delete OS/2 WARP and any preinstalled OS/2
applications.
(3) It is STRONGLY RECOMMENDED that you update your system BIOS to the latest
BIOS release before installing Windows 95 on your system. Early BIOS releases
do not support Plu & Play or MWAVE under Windows 95. Refer to the BIOS section
for the latest BIOS level for you ThinkPad.
(4) Install Windows 95. On ThinkPad's with internal CD-ROM Drives, Windows 95
comes with a generic ATAPI CD-ROM driver and it will work with the ThinkPad
integrated CD-ROM. To make sure that you are using Windows 95 generic ATAPI
CD-ROM driver, remove the following driver from CONFIG.SYS: IBMTPCD.SYS.
(5) The ThinkPad Features Program for Windows works on Windows 95. If you
install Windows 95 on a blank hard disk or you haven't installed ThinkPad
Features Program, follow the instructions of "ThinkPad Features Program -
Installing for Windows" in the ThinkPad User's Guide. Please ensure that you
are at the latest levels (refer to Driver Levels section of this document).
(6) Windows 95 comes with the integrated PCMCIA support. To use the Windows 95
PCMCIA support functions, refer to the Windows 95 documentation or on-line
help. Note: to use PCMCIA function, you must run the PC Card Wizard in Control
Panel under My Computer.
If you want to use ThinkPad PC Card Director (or EasyPlaying), you can still
use ThinkPad DOS PCMCIA device drivers. Follow the instructions in the
ThinkPad User's Guide for "Installing the PCMCIA drivers - Installing for DOS."
Make sure that you use the latest PCMCIA drivers.
(7) To install MWAVE Modem and Audio support, obtain the latest MWAVE DOS and
MWAVE Windows 95 Drivers from the IBM BBS.
(8) You can use ThinkPad Infrared device driver on Windows 95. If you don't
have ThinkPad Infrared device driver version 2.01, you may encounter some
problems. Refer to the Driver Levels section of this document.
(9) The ThinkPad 755CD and 755CDV provide Enhanced Video. You can use ThinkPad
Enhanced video device driver on Windows 95. If you don't have ThinkPad Utility
diskette version 3.10 or later, you may encounter some problems when you change
or setup enhanced video functions.
(10) If you are using an IBM PCMCIA Token-Ring Adapter, download TRCC1.EXE
for an updated driver for Windows 95.
(11) Windows 95 treats the IBM Ethernet Credit Card Adapter II as a Plug & Play
Adapter. However, some older versions of this adapter do not support Plug &
Play. If you insert this adapter into a system running Windows 95, the system
may lock until you remove the adapter. To correctly configure this adapter for
Windows 95, boot in Safe Mode, go into Device Manager, and manually configure
the adpater for I/O 300, IRQ 9, Mem Address D400.
Installing Windows NT 4.0 on the ThinkPad 755Ce, 755Cse, 755CD, 755CDV,
755CV, & 755CX
(1) Update your system BIOS to the latest BIOS release before installing Windows
NT on your system.
(2) Download the latest ThinkPad Windows NT 4.0 Installation Instructions
(TPWINT40.TXT) from the IBM BBS or Web site. Also download the latest drivers
required for your system (see Drivers for Windows NT section for the files to
download).
(3) Install Windows NT on the ThinkPad.
(4) Windows NT 4.0 should automatically detect the ThinkPad 755Ce, 755Cse,
755CD, 755CDV, 755CV, and 755CX video controller and install a Western Digital
90C24A display driver.
(5) Install the ThinkPad Power Management driver. Once you install the
ThinkPad Power Management driver, Suspend/Resume and Power Management are
supported under Windows NT.
(6) Install the Windows NT version ThinkPad Utilities program. Using this
program, you can change your hardware configuration, display the fuel gauge,
and set the device stand-by timers (same as in the Windows 3.1 or Windows 95
environments). Logoff and log back on to enable the ThinkPad Utilities.
(7) Windows NT Audio & Modem Support is provided via MWAVE files from the IBM
BBS. Before installing MWAVE support, verify that the MWAVE DSP is enabled
in the ThinkPad Features program. Then, install MWAVE support for Windows NT
(for MWAVE systems).
(8) Install Thinkpad infrared support using the file from the IBM BBS.
Currently, the following functions are not supported on Windows NT:
Enhanced video function (755CD, 755CDV) such as video overlay features
are not supported.
Hibernation functions are not supported on NTFS partitions.
Windows NT supports the IBM Dock-I and Dock-II. However, hot/warm docking is

THINKPAD DOS/WINDOWS MEMORY MANAGEMENT TIPS
IBM Card/Socket Services Drivers for TP 755Ce,755Cse,755CD,755CDV,755CV, &
755CX
DEVICEHIGH=C:\THINKPAD\IBMDSS01.SYS /D (DOS PCMCIA Socket Services
Driver PCMCIA Socket
Services 2.1)
The /D parameter allows warm docking when used with a Dock II docking station.
If you are not using a Dock II then removing the /D parameter will reduce the
amount of upper memory this driver uses by approximately 1KB. Socket Services
uses between 6KB and 7KB of memory .
DEVICEHIGH=C:\THINKPAD\IBMDOSCS.SYS (DOS PCMCIA Card Services
Driver for PCMCIA Socket
Services 2.1)
Card Services uses 29KB of memory.
DEVICEHIGH=C:\THINKPAD\DICRMU01.SYS /MA=C800-CFFF (DOS PCMCIA Resource Map
Utility)
The /MA parameter tells Card Services what locations in upper memory can be
used by PCMCIA cards or Card Services, and must match or be a subset of an
excluded memory range on the EMM386 line. The PCMCIA Resource Memory Map
Utility Driver does not remain in memory.
DEVICEHIGH=C:\THINKPAD\$ICPMDOS.SYS (DOS PC Card Power
Management Driver)
This driver uses 3KB of memory.
DEVICEHIGH=C:\THINKPAD\AUTODRV.SYS C:\THINKPAD\AUTODRV.INI
This statement loads the PCMCIA Super Client Driver (AUTODRV.SYS) into upper
memory. AUTODRV.SYS recognizes many popular modems, 3270 cards, and SCSI
cards. It does not recognize 5250 PCMCIA cards, SDLC cards, or LAN PCMCIA
cards. AUTODRV.SYS uses 13KB of memory.
Please note that Card & Socket Services also requires a 4KB block of upper
memory.
IBM MWAVE DSP DOS Drivers for ThinkPad 755Ce, 755Cse, 755CD, 755CDV, 755CV, &
755CX
DEVICEHIGH=C:\MWD\MANAGER\MWDP0400.EXE (MWAVE DSP Driver)
The MWAVE DSP DOS Driver uses 2KB of memory .
THINKPAD DOS/WINDOWS MEMORY MANAGEMENT TIPS
VESA Video Driver for ThinkPad 755Ce, 755Cse, 755CD, 755CDV, 755CV, & 755CX
(1) The ThinkPad 360, 750, 755C, and 755Cs Models required a VESA Video Driver
(VESA.EXE) for VESA support. The ThinkPad 755Ce, 755Cse, and 755CD include
VESA support in the Video BIOS. Therefore, no VESA Video Driver is required
for these models.
IBM MWAVE DSP Windows Drivers for ThinkPad 755Ce, 755Cse, 755CD, 755CDV,
755CV, & 755CX
(1) Version 1.00 MWAVE drivers required a large amount of memory below 1MB in
the Windows environment, often limiting the number or Windows applications that
could be loaded at one time. Please update to the latest MWAVE Drivers
Disabling SCSI BIOS in ThinkPad DOCK II
(1) If you are not using a SCSI device in the DOCK II or are only using the
internal SCSI CD-ROM, you can disable SCSI BIOS and reclaim 16KB of upper
memory. SCSI BIOS can be disabled by rebooting the system while in the DOCK
II, pressing Ctrl A at the prompt, selecting Configure/View Host Adapter
Settings, and changing Host Adapter BIOS to Disabled. SCSI BIOS can also be
disabled by removing the DOCK II's cover and changing the switch settings on
the DIP switch block: Switch 1, 2, and 3 to ON. Do not change switch 4.
Memory Management Without PCMCIA Cards
(1) If you do not intend to use PCMCIA Cards, there is no reason to load Card &
Socket Services Drivers. Remove all IBM Card and Socket Services Device
Drivers from CONFIG.SYS (See previous page).
(2) Card & Socket Services Drivers are not required to use the MWAVE DSP Modem
or DSP Audio functions.
(3) Review the ThinkPad Memory Map for your system. Include any upper memory
areas not used by adapter cards in the Docking Station. Be sure to exclude the
address of the SCSI adapter in the Docking Station if SCSI support is needed.
(4) If you are not using the monochrome video mode (most applications do not),
the Monochrome Video Area (B000 - B7FF) may be mapped (by adding I=B000-B7FF to
the EMM386.EXE line in CONFIG.SYS). If using Microsoft Windows, add a
Device=C:\DOS\MONOUMB.386 statement to the [386Ehn] section of SYSTEM.INI.
THINKPAD DOS/WINDOWS MEMORY MANAGEMENT TIPS
Memory Management With PCMCIA Cards
(1) Many PCMCIA card manufacturers provide Point Enablers with their products.
Point Enablers are small programs that provide an interface directly to the
PCMCIA controller; therefore they must be written to support a particular type
of controller.
Point Enablers are relatively simple to configure, do not require Card & Socket
Services Drivers, consume no memory (they remove themselves from memory after
configuring the card), and provide the maximum DOS memory for your ThinkPad.
However, with Point Enablers, you must specify the slot number of the card
(therefore , the card must always be in a specific slot). You must also
manually assign any upper memory blocks and IRQs used by that card. In
addition, hot-plugging of the card is prohibited (in fact, it may damage the
card).
If Point Enablers are provided with the PCMCIA card(s) you are using, decide
whether to use the Point Enablers or Card & Socket Services.
(2) If you use Card & Socket Services, decide whether to use the Super Client
Driver (AUTODRV.SYS) or the drivers that are provided with your PCMCIA card(s).
The Super Client Driver automatically recognizes many popular PCMCIA cards
(including modems, 3270 cards, and SCSI adapters -- it does not recognize 5250
PCMCIA cards, SDLC cards, or LAN PCMCIA cards.). However, the Super Client
Driver can consume more memory than do the drivers provided with the PCMCIA
card.
(3) Determine the amount and location of upper memory required by your PCMCIA
card(s), Docking Station, and ISA Adapter cards. If possible, locate upper
memory required by all PCMCIA cards and ISA Adapters in one contiguous block.
If using Card & Socket Services, these drivers require a 4KB upper memory block
that can be located anywhere in upper memory.
(4) Review the ThinkPad Memory Map for your system. Exclude from EMM386.EXE's
usage the upper memory areas used by (a) the PCMCIA card(s), (b) Card & Socket
Services (4KB), (c) the upper memory area used by the SCSI Adapter in the
ThinkPad Docking Station (if applicable), and (d) the upper memory areas used
by any ISA adapters in the ThinkPad Docking Station. Include any available
upper memory areas not excluded above.
(5) If using Card & Socket Services, modify the DEVICE=C:\THINKPAD\DICRMU01.SYS
/MA=XXXX-XXXX line in CONFIG.SYS. Make the XXXX-XXXX range match the upper
memory area used by any PCMCIA cards (plus the 4KB used by Card & Socket
Services).
(6) Exclude any memory area allocated to PCMCIA Cards from usage by Microsoft
Windows by adding an EmmExclude=XXXX-XXXX line to the [386Enh] section of the
SYSTEM.INI File. Where XXXX-XXXX is the upper memory range allocated to the
PCMCIA cards. If you are using Card & Socket Services, the EmmExclude range
must match the /MA= range of the DICRMU01.SYS Driver.
(7) If you are not using the monochrome video mode (most applications do not),
the Monochrome Video Area (B000-B7FF) may be mapped (by adding I=B000-B7FF to
the EMM386.EXE line in CONFIG.SYS). If using Microsoft Windows, add a
Device=C:\DOS\MONOUMB.386 statement to the [386Ehn] section of SYSTEM.INI.
(8) If you are using an IBM PCMCIA Token-Ring Adapter, and IBM Token-Ring
Adapter in a Docking Station, or an IBM EtherJet Adapter in a Docking Station,
download the IBM LAN Client Code from the IBM BBS. This code loads 802.2
Support, Netbios, the Netware Requester, and a TCP/IP stack into extended
memory (not upper memory). It can reduce the DOS memory consumption of these
protocols to 5KB.

IBM PCMCIA MODEM CONFIGURATION
Using the IBM Super Client Driver (AUTODRV.SYS)
(1) The IBM Super Client Driver will automatically recognize IBM PCMCIA Modems.
Sample CONFIG.SYS file:
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE NOEMS X=C800-CFFF
DEVICE=C:\THINKPAD\IBMDSS01.SYS
DEVICE=C:\THINKPAD\IBMDOSCS.SYS
DEVICE=C:\THINKPAD\DICRMU01.SYS /MA=C800-CFFF
DEVICE=C:\THINKPAD\$ICPMDOS.SYS
DEVICE=C:\THINKPAD\AUTODRV.SYS C:\THINKPAD\AUTODRV.INI
Using the IBM PCMCIA Modem Point Enabler (Note: Not All IBM PCMCIA Modems
Support this Point Enabler)
(1) The IBM PCMCIA Modem Point Enabler (called PCCOMDOS.SYS) does not require
Card & Socket Services. It does reside in memory and requires 16KB. Using the
Point Enabler can save up to 36KB (if you do not load Card & Socket Services or
AUTODRV.SYS). However, with the IBM Point Enabler hot-plugging of the card is
prohibited (in fact, it will damage the card).
(2) Be sure to exclude a 4KB block for the modem in upper memory. If you are also using card
services, do not include the 4KB block in the /MA=XXXX-XXXX parameter of the
DICRMU01.SYS driver.
(3) Sample CONFIG.SYS file:
DEVICE=C:\PCCOMDOS\PCCOMDOS.SYS COM2 /BEEP /WINBIOS /AMEM CE
Where: COM2 is the COM 1, 2, 3, or 4 COM 2 is recommended
/AMEM is the memory location CE00 is recommended
for the modem's 4KB block
Using the IBM PCMCIA Modem Driver
(1) The IBM PCMCIA Modem Driver (called ESTDFM.EXE) does require Card & Socket
Services. It does reside in memory and requires 25KB. Therefore, I recommend
that you use the AUTODRV.SYS driver since it takes less memory. ESTDFM.EXE is
loaded via the AUTOEXEC.BAT:
ESTDFM.EXE S1C2 Where: S1 is the Slot Number
C2 is the Communications Port (C1, C2, C3, or C4)
MEGAHERTZ MODEM CONFIGURATION
Using the IBM Super Client Driver (AUTODRV.SYS)
(1) The IBM Super Client Driver will automatically recognize most Megahertz
PCMCIA Modems. Sample CONFIG.SYS file:
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE NOEMS X=C800-CFFF
DEVICE=C:\THINKPAD\IBMDSS01.SYS
DEVICE=C:\THINKPAD\IBMDOSCS.SYS
DEVICE=C:\THINKPAD\DICRMU01.SYS /MA=C800-CFFF
DEVICE=C:\THINKPAD\$ICPMDOS.SYS
DEVICE=C:\THINKPAD\AUTODRV.SYS C:\THINKPAD\AUTODRV.INI
Using the MegaHertz PCMCIA Modem Point Enabler
(1) The MegaHertz PCMCIA Modem Point Enabler (called SETMHZ.EXE) does not
require Card & Socket Services. In addition, it removes itself from memory
once it has configured the modem. This can save up to 49KB (if you eliminate
Card & Socket Services). However, with the MegaHertz Point Enabler, you must
specify the slot number of the card (therefore, the card must always be in a
specific slot). In addition, hot-plugging of the card is prohibited (in fact,
it will physically damage the card).
(2) Obtain the latest Megahertz Point Enabler. Versions before 3.1 do not
support the ThinkPad 755. Latest version is 4.3. Be sure to exclude a
4KB block for the modem in upper memory. If you are also using card
services, do not include the 4KB block in the /MA=XXXX-XXXX parameter of the
DICRMU01.SYS driver.
(3) The SETMHZ program is loaded via the AUTOEXEC.BAT file. Format of the
SETMHZ.EXE Program:
SETMHZ.EXE /cn /in /sn /pnnnn /dnnnn
Where: /cn is COM 1, 2, 3, 4 COM 2 is recommended
/in is IRQ 1 .. 15 IRQ 3 is recommended
/sn is Slot A, B, C, or D
/pnnnn is the memory location CE00 is recommended
/dnnnn is the delay in milliseconds 1500 is recommended
