This software program updates your ThinkPad''s internal ACP Modem code to the latest ACP V.90 Modem code. This program is for systems using Windows 95-98-NT4. We identify this upgrade as v2.516 which will be consistent with the information you will see in the ThinkPad Modem
QuickTest application.
Note: ACP Modems updated to version 2.516, under certain telephone
line conditions and.0 server modem combinations, may not show
improvement in performance or connectivity compared to prior ACP
Modem V.90 releases. The files V90PAPER.RTF and V90FAQ.RTF provided here, contain answers to many common
questions about V.90 technology (conecsp eds, line conditions,
etc.). Actual connection speed depends on many factors and is often less than the maximum possible.
The following systems are supported
- ThinkPad 600*, 600E, 770*, 770ED*, 770X, 770Z

Installing the V90 Upgrade
- Determine whether your machine is a 600, 600E, 770, 770ED, 770X, or a 770Z which has an internal ACP modem. If not, this code is not appropriate for your machine.
- Before upgrading to the V.90 code, it is important to ensure that you are at the latest level of the base ACP code. Click here to determine if you are at the latest version of the base ACP code .
- Download acp90r2.exe from the IBM Web Site and remember where you downloaded this file to. See the link at bottom of page to download the file.
- Using Windows Explorer, locate the file acp90r2.exe and double-click it to extract the drivers.
- Click Next at the welcome screen to continue the extraction process.
- If you agree to all the terms stated in the license agreement for Non-Warranted Programs, click Next.
- When prompted, click Finish to extract the files to the default destination path. The default location is C:\DRIVERS\WIN\MODEM.
- At the "specified output folder does not exist, create it" window, click Yes.
- The files will extract to the hard drive. Once complete, the installation wizard will start automatically. If you wish to continue the installation, click Yes. If you wish to install the update at a different time, click No. To install the modem at a later time, click Start, then click Run... and type C:\DRIVERS\WIN\MODEM\modemv90.exe and click OK.
- If you clicked Yes, the installation of the V.90 drivers will continue. When you are prompted to restart your computer, close all other applications on your machine, and click Finish to restart your system. When the system restarts, it will redetect all the modem components.
NOTE:
The extraction wizard will leave both ACP90R2.EXE and MODEMV90.EXE on your system. If you need the hard disk space, you can delete either of the two files. If you delete both files, you will need to download ACP90R2.EXE to reinstall the V.90 update.
NOTE:
To uninstall the V.90 update, follow the instructions for uninstalling and reinstalling the ACP modem drivers.
