- *README.TXT Release Notes for Plug and Play Kit *
- * for Windows(TM) *
- *Release 1.41 February 1995 *
- *******************************************************************
-
- Introduction
- ============
-
- This kit contains Release 1.41 of the Plug and Play Kit for
- Windows. The components of this kit are:
-
- Plug and Play Configuration Manager for Windows
- Provides configuration services to real-mode and protected-
- mode drivers and to applications in Windows environments.
-
- Plug and Play ISA Configuration Utility (ICU) for Windows
- 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. A full description of ICU
- features and use is available in the ISA Configuration
- Utility (ICU) User's Guide.
-
- Information on the components of this kit, and on the inclusion
- of the Configuration Manager and the ISA Configuration Utility
- in your products, is available in the Plug and Play Developer's
- Guide.
-

- *******************************************************************
- *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".
-
- 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 2.0, from Intel Corporation
-
- This release of the Configuration Manager supersedes all previous
- releases.
-
- New Features
- ===========
-
- Release 1.41 of the Configuration Manager provides
- the ability to configure Plug and Play ISA devices around
- PCI Bridge Aperture Values, in conformance to the ESCD
- specification v1.03.
-
- Configuration Assist (Cassist) now has support for the
- SatisFAXtion(TM) modem card.
-
- Limitations
- ===========
-
- Please be aware that this release of the Plug and Play
- Configuration Manager for Windows has the following
- limitations:
-
- - The default installation of 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 real-mode MS-DOS environment.
- The CM lock functionality is always available under Windows,
- including the Windows V86 DOS. If this functionality is needed,
- add the /LOCK parameter in the line in config.sys 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) *
- ******************************************************************
-
- This diskette contains Release 1.41 of the Windows
- ISA Configuration Utility (ICU), its ISA card configuration
- database, the Configuration Assistance Utility (cassist), and
- the Configuration Manager software needed to support the 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.
-
- PCMCIA VxD
- ==========
-
- The Windows version of this release installs the following file:
-
- <drive>:\windows\system\pccardrm.386
- This file is a PCMCIA Card Services virtual device driver (VxD).
- The VxD allows the ICU to receive PCMCIA card events as Card
- Services clients on Windows. For this VxD to work properly,
- real mode Card Services must be running on your system.
-
- An entry for this VxD is put into the \windows\system.ini file
- under [386Enh] but is commented out. Edit the file and
- remove the comment character(;) to activate the VxD.
-
- Installation Notes
- ==================
-
- 1) If the Windows screen saver becomes active during the Windows
- ICU setup, the index generator that runs at the end of the
- setup program is iconized as an MS-DOS icon. To complete
- the setup procedure, return to Windows and maximize the
- MS-DOS icon.
-
- 2) The installation procedures in this kit assume that C: is
- the boot drive of the system. Therefore, the procedures
- create, make changes to, or overwrite boot drive files on C:.
- In particular, the procedures put the escd.rf file into C:\,
- and create or modify the config.sys file in C:\.
-
- On systems without the Plug and Play BIOS, if the boot drive
- is not C:, but some other drive, the user must move the
- escd.rf file to the root directory of the boot drive.
- Also, the user must add line that loads the CM driver
- (dwcfgmg.sys) to the config.sys file in the root directory
- of the boot drive.
-
- Some utilities, for example, the Stacker disk compression
- utility, can change the boot drive from C: to another drive.
- Such drive changes are not always obvious to the user. In
- order to avoid the user having to move and edit files, the
- installation procedure must make an INT 21 call to detect
- the boot device before installing the escd.rf file or
- changing the config.sys file.
-
- 3) The Windows ICU installation fails on a system that has MS-DOS
- 6.0 installed with the VSafe virus scanner active if the VSafe
- scanner checks executable files and protects executable files
- (VSafe options 4 and 8).
-
- 4) 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.
-
-
-
- Limitations
- ===========
-
- - If any PCI devices are locked, the ICU will fail when trying to
- reconfigure any 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.
-
- - 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.
-
- - 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.
-
- - 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.
-
- - If the ICU reports that a card is not configurable, you can
- usually find the source of the error by attempting to modify the
- function that is in the error state. This action produces a
- message that identifies the problem card.
-
- - 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 Plug and Play cards to all the
- valid PCI card interrupts, then 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.
-
- - You can increase the size of the Smartdrv buffer to make the ICU
- faster.
-
- - 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 <TAB> key and select
- using the space bar. In the messsage dialogs, you must use the
- up and down arrow keys instead for traversal.
-
- - 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.
-
- - In some cases, the ICU may discard some of the resources of
- a locked PCI card. After adding or modifying any cards with
- the ICU, select the locked cards and review their configuration.
- If you see any locked PCI card using a single IRQ and no other
- resources, that card may be missing resources. These resources
- should be restored after you have made all other configuration
- changes, and before you save the configuration from the ICU.
-
- To restore those resources:
- - select the card
- - choose the Modify operation
- - choose the Settings button
- - you will be asked if you would like to modify this function
- even though it is locked; select Yes.
- - change the configuration choice to Disabled, then change it
- back to Enabled; all the necessary resources for this card's
- function will appear
- - choose OK on the Settings screen
- - choose OK on the Configuration screen
-
- You may now save the configuration.
