Installation notes for OS/2 Warp on Toshiba T2150CDS/CDT, and 400CDT
By Clark D. Christensen [76226,3123] 8/8/95
The Toshiba T2150 series fully supports OS/2 Warp, though a few updates,
drivers, and tweaks will be required in order to install it and have everything
work properly. All file downloads referenced are from Toshiba's forum on
CompuServe.
To summarize these changes:
1) OS/2 Warp for Windows (red spined box) does not include support for the
EIDE CD-ROM in the T2150CD or the 400CDT. You'll need to obtain an update to
OS/2 in order for the CD-ROM to work properly with Warp for Windows. Warp
fullpack (blue spined box) includes these updates.
2) OS/2 Warp installs an IRQ15 conflict between the CD-ROM and the PCMCIA
controller. Don't install PCMCIA support on the original installation. Use
OS/2's Selective Install utility to add PCMCIA support later. Using Selective
Install later will allow you to edit CONFIG.SYS to eliminate the conflict
before you reboot into a conflict.
3) You'll need to download and install the SVGA driver set in order to get
best use out of your T2150, or 400 display.
4) On the 400 Series models, it will be best to disable the built-in serial
port, and set the infrared port to COM1. This will eliminate the need to
explicitly configure your PCMCIA modem to use COM3 and IRQ5. If you have an
external modem, and not a PCMCIA modem, you can configure the built-in serial
port as COM1 and the infrared port as COM2. The 400 series uses a 16550
compatible buffered UART, so high speed data communications are supported on
external modems as well as PCMCIA modems.
************Warp for Windows (red box) Section*****************************
If you're planning to install OS/2 Warp for Windows (red spined box), then this
section is specifically for you. Warp fullpack users should proceed to the
fullpack specific section.
Warp for Windows users will need to download:

ATAPI.ZIP

Title : OS/2 IDE CD-ROM drivers
Keywords: OS2 WARP 2.1 2.11 CD-ROM IDE ATAPI 5302B 2150 T2150
IBM OS/2 2.x / 3.x IDE CD driver for IDE CDROM drives.
This file includes support for the CD-ROM drive in the T2150CD and the
5302B IDE CD-ROM drive under Warp for Windows.
See README.TXT in ZIP file for INSTALL details.
This package also contains several modifications to the driver which allow
certain IDE CDROMs with not 100% compliant HW to work with OS/2. It is a
LATER Driver than the one shipped on the WARP Full Pack.
NOTE: If you are INSTALLED and working, you DO NOT NEED this driver.
It is recommended that you read and understand the instructions carefully
before you install these updates.
It is also recommended that you install these updates to a copy of the
installation disk #1 before you install OS/2 on your machine. If you need
extra space on the install disk 1, you can delete some of the numerous SCSI
drivers from the diskette (AHA*.ADD), and any reference to those drivers in the
CONFIG.SYS on Disk 1. Please do this on a COPY of Disk 1.
OS/2 Warp installs an IRQ15 conflict between the CD-ROM and the PCMCIA
controller. Don't install PCMCIA support on the original installation. Use
OS/2's Selective Install utility to add that support later. Using Selective
Install later will allow you to edit CONFIG.SYS to eliminate the conflict
before you reboot into a conflict.
Install OS/2 Warp. When you get to the screen where you choose the hardware
selections, please choose the following:
Primary Video: VGA (we'll install the Chips & Technologies drivers later)
CD-ROM: "Unlisted IDE CD-ROM"
Multimedia (sound system): ESS688
PCMCIA: Toshiba T4800 (wait for later to install this support)
Advanced Power Management: Yes
Finish the installation,and reboot a couple of times to be certain that what
you have already installed is working properly.
Next, you can use Selective Install (in the System Setup folder) to install the
PCMCIA support. Only install the support for PCMCIA devices that you have
(modem, hard disk, or flash). Select Toshiba T4800, and install the files.
Before you reboot, you'll need to edit CONFIG.SYS to eliminate the IRQ15
conflict.
Change the line that reads:
BASEDEV=IBM2TOS1.SYS /s0=2 /c0=15
to read
BASEDEV=IBM2TOS1.SYS /s0=2 /c0=11
Save, shutdown, and reboot. This will change the IRQ for the PCMCIA controller
to IRQ11.
Test the PCMCIA devices that you have to be certain that they work.

to read
DEVICE=PCMCIA.SYS /P
Change the line that reads:
BASEDEV=IBM2TOS1.SYS /s0=2 /c0=15
to read
BASEDEV=IBM2TOS1.SYS /s0=2
Save, shutdown, and reboot. This will eliminate the need for an IRQ for the
PCMCIA controller, telling OS/2 to poll the controller instead.
Test the PCMCIA devices that you have to be certain that they work.

Title : OS/2 SVGA driver set for T4900CT
Keywords: OS2 T4900 T4900CT CHIPS VIDEO SVGA DISK IMAGE WARP
Warp OS/2 Display drivers for the T4900CT. Please see the installation
notes in the README.1ST and READ.ME files prior to installing. This file
contains a diskette image of the installation diskette.
Requires the LOADDF.ZIP utilities in this library in order to make the
install diskette.
If you have OS/2 on CD-ROM, you already have LOADDSKF.EXE on your Warp CD-ROM,
so you will not need to download LOADDF.ZIP. Just copy LOADDSKF.EXE from the
Warp CD-ROM to the directory where you have unzipped the contents of
OS2CTDSK.ZIP.
To install, follow the instructions in the README files contained in
OS2CTDSK.ZIP
This driver set will do up to 64K colors at 640x480 on the built-in display of
active color models (T2150CDT, 400CDT), and 265 colors at 640x480 on the
dual-scan models (T2150CDS, 400CS).
This driver set also supports a virtual or "panning" mode on the active color
models' (T2150CDT, 400CDT) built-in display in screen resolutions higher than
640x480. What this does is shows part of the high resolution screen display,
and the picture pans (scrolls) as the mouse pointer approaches the edge of the
screen. This doesn't seem to be supported on the dual-scan models (the panning
doesn't work, but the system is usable within the limits of what you can see on
the screen.). This is useful for those of us that use an external monitor at
800x600 or 1024x768, and forget to reset the display resolution before
disconnecting the monitor. In my opinion, it is not really useful for everyday
use.
The README file on the installation diskette for the SVGA driver set mentions
some limitations in using WinOS2 full screen sessions with this driver set. I
interpret this to say that if you have an OS/2 full screen session open, you
should not also have a WinOS2 windowed session, or use Alt-Home to switch a DOS
windowed session to full-screen or vice-versa.
Lastly, you'll need to edit Windows/WinOS2 SYSTEM.INI so that 256 colors is
supported for WinOS2 sessions. You'll need to remark out the line:
display.drv=vga.drv
by putting a semicolon as the first character in the line. Then add the line:
display.drv=wvgx8f.drv
If you encounter a problem in booting back to native DOS/Windows, you'll need
to remove the semicolon from the vga.drv line and put a semicolon at the
beginning of the wvgx8f.drv line.
