******************************************************************* *README.TXT Release Notes for Plug and Play Kit * * for MS-DOS(R) * *Release 1.43 May 1995 * ******************************************************************* Introduction ============ This kit contains Release 1.43 of the Plug and Play Kit for MS-DOS. This release of the Plug and Play Kit for MS-DOS supersedes all previous releases. The components of this kit are: Plug and Play Configuration Manager (CM) for MS-DOS Provides configuration services to real-mode and protected- mode drivers and to applications in MS-DOS environments. Plug and Play ISA Configuration Utility (ICU) for MS-DOS Provides a way to assign system resources to add-in cards before the card is installed. This assignment avoids resource conflicts and keeps track of system resources so that Plug and Play cards do not conflict with non-Plug and Play cards in a system. ******************************************************************* *Plug and Play Configuration Manager (CM) * ******************************************************************* The Plug and Play Configuration Manager provides all of the functionality defined in the "Plug and Play Device Driver Specification for Microsoft(R) Windows(TM) and MS-DOS(R)". The Configuration Manager also complies with the specifications and definitions in: "Plug and Play ISA Specification", Version 1.0a from Intel Corporation and Microsoft Corporation "Plug and Play BIOS Specification", Version 1.0a from Intel Corporation, Compaq Computer Corporation, Phoenix Technologies, Ltd., and Microsoft Corporation "Plug and Play BIOS Extensions Guide", Version 1.1 from Intel Corporation "PCI BIOS Specification", Version 2.1, from Intel Corporation Configuration Manager Limitations ================================= Please be aware that this release of the Plug and Play Configuration Manager for MS-DOS has the following limitations: - The default installation of the MS-DOS CM driver invokes the driver with the 'lock' device function of the CM provided by the CM_LockConfig and CM_UnlockConfig functions unavailable to PC add-in install programs running in a real-mode MS-DOS environment. If the CM driver for Windows is also installed, the CM lock functionality is always available under Windows, including the Windows V86 DOS. If this functionality is needed, add the /LOCK parameter to the line in your CONFIG.SYS file that invokes the CM driver, DWCFGMG.SYS. CM_LockConfig and CM_UnlockConfig are unrelated to the locking options available with ECU or ICU utilities. - In the absence of the Intel Plug and Play BIOS extensions, Plug and Play boot devices are not reconfigured by the Configuration Manager. - Calls to the Configuration Manager do not work during sys_critical_init. ****************************************************************** *Plug and Play Kit ISA Configuration Utility (ICU) * ****************************************************************** See the ISA Configuration Utility User's Guide for details on using the Plug and Play ICU. NOTE The ISA Configuration Utility is for ISA systems only. Do not run it on EISA systems. To configure EISA systems, use an EISA Configuration Utility. ICU Limitations =============== Please be aware that this release of the Plug and Play ISA Configuration Utility for MS-DOS has the following limitations: - Some portions of the ICU may not fit on the screen if you are using VGA resolution. If this happens, you can see the missing information by moving the displayed item back onto the screen. Click on the title bar of the displayed item, and move the item to the desired location. - Double clicking to select an item in a list is not supported. - If any PCI devices are locked, the ICU may fail when trying to reconfigure other PCI devices. To work around this limitation, unlock all PCI devices while adding or modifying other cards. You may lock the PCI devices again before saving the configuration. - Pressing the F1 key invokes the ICU help facility from the ISA Configuration Utility window (the main window) only. - When you are modifying a function of a Plug and Play card in preparation for locking it, you might see a conflict message that indicates the card is conflicting with itself. Try reconfiguring the card functions in a different order. - If a function has two or more resource types that must be configured together, the ICU might not be able to configure that function, even though there might be a valid configuration available. See the discussion on resolving conflicts in the Troubleshooting section of the ICU User's Guide for ways to successfully configure functions in this category. - When you pick a resource for a new card that is currently used by an existing card, the ICU reconfigures the Plug and Play ISA cards first, then the PCI cards. However, PCI cards are restricted to specific interrupts. Sometimes the configuration fails because the ICU assigns all the valid PCI interrupts to the Plug and Play cards, so that it cannot configure the PCI cards. Use the ICU to reconfigure the Plug and Play cards to different interrupts, then try again to configure your new card. Operational Hints ================= - Run the MS-DOS installations for the kit components from MS-DOS, not from an MS-DOS window under Windows. - The MS-DOS install program on these diskettes is incompatible with the expanded memory manager. Before installing the Plug and Play kit for MS-DOS, disable your expanded memory manager. After you have finished the installation, you can enable the expanded memory manager again. - The MS-DOS ICU installation might fail if some Terminate and Stay Resident (TSR) programs or drivers are resident in memory. If this happens, remove all TSRs from memory and restart the install process. Some example TSRs and drivers are: Borland Side Kick and network drivers that are not loaded from config.sys. - You must execute the MS-DOS ICU from MS-DOS only, not from an MS-DOS window. If you want to use the MS-DOS ICU from an MS-DOS window, the Windows ICU must also be installed on the system. - If you are upgrading from a previous version of the ICU, any user-entered names for unlisted cards are lost and will have to be re-entered. - When you save an image file (Save Image File or Save Image File As.. on the Advanced menu), the icu.ndx index file is not updated. So if the configuration you saved contained one or more unlisted cards, when you load the image file you saved, the card resources for these unlisted cards are in the loaded configuration image. However, cards of this type might be listed as "Unknown Card," instead of by the name you assigned when you added it. You can avoid this behavior by choosing the Save item on the File menu before you save the image file. In addition, if you copy the image file to another system, you must also copy the icu.ndx index file to avoid this behavior. - After using the ICU load image file operation, you must save the changes and reboot your system before making any other changes. If you don't, you will see inconsistent behavior. - When a PCI or Plug and Play ISA card is modified, the ICU asks you to verify that the card is configured as shown. This step is unnecessary; the card will be automatically configured as shown when the system next boots. - Configuration Assistance Utility (cassist) operation is incompatible with Plug and Play cards. Remove all Plug and Play cards from your system before running cassist. Failure to do so may result in system failure. Replace the cards after you have run cassist. - If you have no mouse, you may experience changes in the keyboard interface. In most cases you can still traverse buttons, list boxes and menus in the dialog boxes using the <TAB> key, and select using the space bar. In the message dialogs, you must use the up and down arrow keys or page up and page down keys instead for traversal. - This release of the ICU includes PCMCIA Revision 2.10 support. This does not include support for CardBus or DMA, which were added to the new PC-Card Standard. To enable this support, Card Services must be running on your system. ******************************************************************* Trademark and Copyright Citations ================================= MS-DOS is a registered trademark, and Windows is a trademark of Microsoft Corporation.
