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. Refer to the last page of this document for
instructions on downloading files from IBM's BBS and Internet sites.
(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 levels.
(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 the IBM Docking Station, and any ISA Adapters installed in the docking
station. Refer to the ThinkPad Memory Map and the ThinkPad Dock II Memory Map
sections.
The Device Driver DICRMU01.SYS /MA=CA00-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.
(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 Station, 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) Please note that early releases of ThinkPad 701 Audio Drivers could cause a
conflict with a Token-Ring Adapter installed in the docking station. Please
update to the latest ThinkPad 701 Audio Drivers.
Installing Windows 95 on the ThinkPad 701
(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. Refer to the BIOS
section for the latest BIOS level for you ThinkPad.
(4) Install Windows 95.
(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) For Windows 95 audio support, please download the TP 701 Windows 95 Audio
Drivers from the IBM BBS or FTP site.
(8) If you are using an IBM PCMCIA Token-Ring Adapter, download TRCC1.EXE
for an updated driver for Windows 95.
(9) 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.

To view the BIOS Part Number, press Function F1, then turn to page 4. To get
the latest BIOS for the ThinkPad 701, download SYS7013O.EXE from the IBM BBS.
Upgrading The ThinkPad Flash BIOS
- You need an AC adapter and a charged battery pack to update the system
program.
- If your computer is attached to a ThinkPad Docking Station or a port
replicator, turn off the computer and detach it before proceeding.
(1) Plug in the AC adapter and make sure the battery is installed. It is
important that the computer have BOTH sources of power available. (If power
is lost during the update the computer may have to be sent in for service).
(2) Enter the Configuration Utility by pressing Fn-F1. Page Down to the fourth
page of the menu. Check "Startup Sequence". It should be set to "Smart" or
"Conventional", but not "Hard Disk".
(3) Insert the BIOS Update Diskette into the diskette drive. Power on the
machine (a quick punch of the Power Button). This will reboot the computer
from the update diskette.
(4) Follow the instructions on the screen.
(5) When you are told to press the power button, push and hold the Power Button
for at least 3 seconds. This will begin the BIOS flash update.
(6) Continue following the prompts. When you see a bar graph with "*"s, do NOT
touch anything, especially not the main power switch.
(7) When the "Program completed successfully" appears, it is safe to turn your
machine OFF. Remove the diskette from the drive before turning the machine
back ON (the diskette is no longer needed).
(8) At Power On, you will see error messages, but don't be concerned. Press
"ENTER", make any desired changes in the Configuration Utility, press "ESC",
and select "Yes" to save the Configuration.

THINKPAD DOS/WINDOWS MEMORY MANAGEMENT TIPS
IBM Card & Socket Services Drivers for ThinkPad 701C & 701Cs
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=D000-D7FF (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.
THINKPAD DOS/WINDOWS MEMORY MANAGEMENT TIPS
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 your do not intend to use PCMCIA Cards, there is no reason to load Card
& Socket Services. 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 ThinkPad 701's
Internal Modem or 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 Ô386EhnÒ section of SYSTEM.INI.
(5) If you are using an IBM PCMCIA Token-Ring Adapter, an 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.
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 useage by Microsoft
Windows by adding an EmmExclude=XXXX-XXXX line to the Ô386EnhÒ 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.
(6) 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 Ô386EhnÒ section of SYSTEM.INI.
