OS/2 Warp Compatible Hardware List Web site: NoteBook/2 web site
I started with OS/2 version 2.1 in 1993, on a 386SX 16 MHz computer. I could
do things with it we now take for granted, like using WordPerfect while my modem
picked up my mail from the Fido network. I have to use Windows NT during the
day at work, but that desktop (if you can call it a desktop) is not as comfortable
to me as is OS/2's WorkPlace Shell.
Before this T23 I used a Dell Inspiron 3200 notebook, after some time I was
able to get everything working under OS/2 4 Warp. I used it for about two year
until I had to replace it because of an accident. After this I bought a Thinkpad
R30, this was a mistake because this notebook was not suitable for OS/2. There
were no drivers for the audio and video (it run in a non-accelerated VESA mode)
and I had a hard time getting OS/2 installed on it in the first place. It did
not work correctly, so I decided to sell it and buy another laptop.
As usual, IBM offers its clients a broad range of choices concerning ThinkPads.
The T23 comes in different models, and can even be ordered with OS/2 Warp V4
pre-installed. The T23 comes in different models.
All models have a diskette drive, internal microphone, are RFID-enabled, have
Port Replicator / Dock support, ergonomic keyboard with palm rest, TrackPoint
pointing device, 2 Type II or 1 Type III PC Card (TI Solution), 2 USB Ports,
Serial, Parallel and UltraPort connectors, S-Video out, IR, audio, headphone,
line out, AC adapter, RJ-11 and RJ-45 adapters.
All are shipped with the S3 Graphics SuperSavage IXc with 16MB SDRAM. Different
CPU speeds vary upon a specific model. The 2647 model (9SU, 5SU, 9RU, 5RU) have
an extra display resolution up to 1400*1050, whereas all others only have a
maximum resolution of 1024*768. Hard disk capacity also varies from the model,
and can even be modified to suite better your personal needs. Models 6GU, 2GU,
8SU, 4SU, 8RU, 4RU, 9SU, 5SU,9RU, 5RU come with 256 MB of 133MHz SDRAM, other
only with a disappointing 128MB. All models (except 2647 6RU and 5RU) come with
CD-RW/DVD combo drive. All versions ship with an on-board Lucent 56K modem,
and an Intel on-board 10/100Mbps NIC, and 9SU, 5SU, 8SU, 4SU also have a wireless
IEEE802.11b solution on-board. As usual different batteries and accessories
are available (as options).
2. The Ordering Experience
After looking around, I decided to buy an already older model. Not only was
the T23 affordable, compared to the newer models, but there was also official
OS/2 support from IBM. I ordered the system, together with an extended warranty,
in the beginning of 2003 from Bluelink, an IBM dealer in The Netherlands.

4. System Set-Up and Installing eComStation
The system had Windows 2000 installed on one large FAT32 partition and a recovery
partition of about 700MB. I deleted the recovery partition (after backing it
up with DriveImage) and shrunk the C-partition with Partition Magic to about
7 GB. In order to get OS/2 installed quickly I restored my R30 backup of eComStation
1.0 on a 5 GB partition. I only had to install the audio drivers and use another
driver for the PCMCIA-support. After that I created a HPFS-partition for data
and one FAT32 for my 10GB collection of MP3-files. In Windows 2000 I installed
the NT HPFS-driver to be able to share data.
When I received my copy of eComStation 1.1, I decided to choose a clean install
(after I made a backup of my 1.0 installation). In about a half hour I had a
working system, the only thing I had to install myself were the audio drivers.
4.2. Installing Device Drivers
For those of you who want to install Warp 4 on the T23 you can download the
The T23 has an Intel AC'97 Audio Chipset (CS4229 AC97 codec), for this chipset
are two drivers available. One provided by IBM and the other ported from the
Linux ALSA driver. I only tried the driver from IBM, it works fine but lacks
MIDI support. The sound quality in VPC is poor, maybe I should try the UNIAUD
driver to see if this works better, I was told this driver would offer better performance and effectively includes MIDI support.
The implemented video chipset is S3's 86C584 SuperSavage/IXC.
I'm using Scitech SNAP Graphics 2.1.3 without any problems at all to drive the
S3 video card and the T23's 1024 x 768 @ 16777216 color, 14.1" TFT XGA
display. There is also a special device driver (see reference above), however,
Scitech delivers much higher performance.
Only at the beginning of this year a working driver for the build-in Lucent
modem came available, I used it a couple of times and it worked fine. I also
have a Psion PCMCIA modem/ISDN adapter. The modem that comes with T23 is the
Lucent/Agere LT WinModem 56k.
4.6. Pointing Devices
I don't use the TrackPoint pointing device and touchpad that often, because
I prefer a mouse. The mouse I use is an IBM USB scroll mouse. However, there
should be no problem using the TrackPoint navigation system with OS/2 Warp's
base device drivers.
I use the build in Intel 10/100 NIC to access my network (NetBIOS) and the
Internet. This model does not have a internal WIFI card, I am using an Artem
PCMCIA WIFI card instead. In my CONFIG.SYS I load both drivers and I have two
Rexx files to switch from one NIC to the other:
/* turn on the radio
* This command activates the 802.11b interface
* original batch file by Neil Waldhauer
* The wireless NIC should be inserted in the PC Card slot
say "Activating the wireless network card"
' ifconfig lan0 down'
' ifconfig lan0 delete'
'dhcpstrt -i lan1 -d 10'
say "Wireless networking enabled"
/* turn off the radio
* This command deactivates the 802.11b interface
say "Deactivating the wireless network card"
' ifconfig lan1 down'
' ifconfig lan1 delete'
'dhcpstrt -i lan0 -d 10'
say "Cable networking enabled"
4.8. PCMCIA Socket Services
The T23 comes with Texas Instruments PCI1420 chipset implemented in the PCMCIA
socket services. Normally, this device should work perfectly with IBM's cardbus.exe
device driver, downloadable via IBM Device Driver Pack On-Line (with valid SWC
or PPA subscription), or with Daniela's patched device driver, and it also works
perfectly with APSoft's device driver.
5. Advanced Power Management
5.1. Battery life
If I use the computer in a normal manner, e.g. for word processing while listening
to my collection of MP3 music, from the hard disk, then my battery will last
for about two and a half hour. I can stretch it more if I reduce the brightness
of the screen and listen to a MP3 stream from the Internet instead.
5.2. Standby and Suspend Issues
The Suspend (Fn4) and the Hibernate (Fn12) function work, but not the way they
should. I had a couple of times problems with Suspend, the keyboard froze after
I resumed the computer and I had to reboot. Hibernate does work without problems.
In order for this to work and to be able to swap the Ultrabay drives I had to
change the following in my config.sys:
BASEDEV=IBM1FLPY.ADD /A:0 /FORCE:1 /U:0 /F:1.44MB
BASEDEV=DANIS506.ADD /A:1 /BM /BAY
If you have the DVD/CDRW-combo drive you need instead:
BASEDEV=DaniATAPI.FLT /A:1 /U:0 /TYPE:ZC
DEVICE=C:\OS2\BOOT\$ICPMOS2.SYS /C0 /G
For hibernation to work you need a hibernation file on the first (FAT) partition
of the hard disk, you can download the utility disk at: http://www-3.ibm.com/pc/support/site.wss/MIGR-4PESMK.html?doctype=
. A problem with this hibernation utility is that it can't coexist with
the OS/2 boot manager, you have to use another boot manager instead, like Air-Boot.
eComStation has two APM settings in the Power object (in the System Setup folder).
One is "APM BIOS and OS/2 support enabled" and the other setting is
"APM BIOS support enabled" If I use the first setting then my CPU
activity will increase to more than 60 % with not many tasks running. So for
normal use I need the second setting (I don't want to drain my battery), the
CPU activity is then only a couple of percent. However with this setting resuming
after a hibernate is not working correct, therefore I have to change the Power
settings to "APM BIOS and OS/2 support enabled" before I use hibernation.
The only problem I have now after a resume is that I loose my mouse pointer.
If I switch to a full screen OS/2 command prompt then my pointer will return.
This is not very user-friendly, but I can live with this.
Suspend and hibernation is not possible if I have my SCSI or WIFI PCMCIA card
in one of the slots. I have to power down the card and remove it before I can
hibernate the machine.
6. Installing Applications
The applications I use the most are Lotus SmartSuite, Mozilla, PMmail, PMInews,
PMview, Warpvision, Z!, Acrobat Reader 4, Virtual PC and RSJ (I have SCSI CD-RW).
7. The Bottom Line
I use the ThinkPad T23 as my main OS/2 work horse, I hardly use the windows
partition on it. The T23 is more flexible (and faster) than my desktop computer.
I can use my system where I like, because of WIFI. The quality of the computer
is excellent and the price was good, because the newer T-models replaced the
T23. I am not very happy with the power management support, because the "suspend"
and the "hibernate" mode don't work as they should. Suspend is possible
in most of the time, but there is always the risk of a frozen keyboard. Hibernate
is safe. I hope that someone has solved this problem and will me tell how.
