PLUG AND PLAY
=============
PCI Systems
-----------
If the video is configured by the BIOS to consume an IRQ and you need
to use the secondary PCI IDE controller in your PC, your video will
work only in VGA mode. To load the accelerated Windows 95 driver for
your video, disable the secondary PCI IDE controller in the BIOS and
the Device Manager (located in the System control panel). Another
alternative (if supported by the BIOS) is to disable the IRQ of the
video device.
IBM Thinkpad Models 750 (all 750 series except 750ce)
-----------------------------------------------------
A new BIOS that solves several problems with power management is
available from IBM's bulletin board. Download the latest System
Program Service Diskette for the Thinkpad 750 from the BBS. See your
hardware documentation for information on how to access the IBM
bulletin board.
IBM Thinkpad Models 755cd, cx, ce, cse, cdv (but not 755c)
----------------------------------------------------------
We are in the process of resolving with IBM several known problems:
1. Mwave is lost if you have more than 8 MB of memory.
- IBM is working on updated drivers. The 1.1 revision does not
solve this problem.
2. If you install Windows 95 into the same directory that contains
your current version of Windows, Mwave will continue to function.
- If you install Windows 95 to a different directory, Mwave will
not work unless you reinstall the Mwave drivers by using IBM's
Mwave setup program disks. This is by design. The Windows 3.1
drivers are required to run the Mwave chip.
3. The infrared port shows up with problems in Device Manager.
- IBM is working on an updated Infrared VxD that resolves this
problem.
4. Docking is not supported.
- IBM is expected to release fixes to their Plug and Play BIOS
shortly, which will enable full Windows 95 Plug and Play and
docking support. For updates to the System Program Service
Diskette for your model of Thinkpad, check IBM's bulletin
board. See your hardware documentation for information about
accessing the bulletin board.
5. There are power management problems with the suspend and resume
commands.
- If you have a 1994 BIOS, you can usually resolve these problems
by upgrading to the latest Flash BIOS revision from 1995. You can
find it on CompuServe, THINKPAD forum, or on IBM's bulletin
board.
See your IBM hardware documentation for information about
accessing the bulletin board.
6. Mwave versions earlier than 1.2 contain numerous bugs.
- These bugs in earlier versions of Mwave cause serious problems
when Mwave is run on Windows 95. For more information, call the
IBM PC HelpCenter.
IBM Thinkpad Dock II
--------------------
If you use IBM Thinkpad Dock II, you must disable the BIOS for the
Adaptec 1530P SCSI controller in the docking station before starting
your computer while it is docked. If you do not, your computer will
hang repeatedly. This controller works fine in protected mode even
without the BIOS enabled, so you should not lose access to any SCSI
devices as a result.
To disable the BIOS:
1. Restart your computer while it is docked.
2. Press CTRL+A to start the Adaptec SCSISelect utility.
3. Choose Configure/View Host Adapter Settings.
4. Choose Advanced Configuration Options.
5. Change the setting for Host Adapter BIOS to Disabled.
Press ESC until you are prompted to exit the utility, at which point
the computer will restart.
An even better solution is to disable the BIOS completely, which will
enable the adapter to run completely in Plug and Play mode. This will
allow its resources to be allocated dynamically at Windows 95 startup.
However, this requires changing a DIP switch inside the dock unit.
For details about disabling the SCSI adapter BIOS, refer to your Dock
II manual.
Micron M5-PI Series
-------------------
Before installing Windows, users of Micron M5-PI series (P-60, P-66)
need to be sure the BIOS read/write jumper(W22) is set to the read-
only position. If you try to install Windows 95 with this jumper in
the read\write position, it may cause BIOS corruption. For more
information, contact Micron Technologies.
Micron P90/100
---------------
Before installing Windows, users of Micron P90 and P100 systems must
make sure their BIOS version is N15 or later. For more information,
contact Micron Technologies.
NEC Versa M and AT&T Globalyst
------------------------------
If you use AT&T Globalyst and NEC Versa M, you must set the BIOS
setting for PCMCIA Power to Enabled before running the PC Card
(PCMCIA) wizard to enable the Windows 95 PCMCIA support. The default
setting is Disabled.
To change the PCMCIA Power setting to Enabled:
1. Restart your computer.
2. When the cursor changes to a rectangle, press F1.
3. When the BIOS configuration program is ready, select Power, and
then change the PCMCIA Power setting to Enabled.
4. Save these settings.
Winbook XP
----------
There is a problem on the Winbook XP which could cause the keyboard
not to function properly. The workaround is to disable Windows 95
power status polling.
To disable Windows 95 power status polling:
1. In Control Panel, double-click the System icon, and then click the
Device Manager tab.
2. Click the plus (+) sign next to the system class you want to
change.
3. Double click Advanced Power Management Support, and then click the
Settings tab.
4. Make sure that the Disable Power Status Polling box is checked.
5. Click OK to save your changes and exit Control Panel.
HP OmniBook 600C
----------------
The Omnibook's PCMCIA controller is supported via special drivers
in the Drivers directory on the CD version of Windows 95.
Refer to the Readme file in the Drivers directory for installation
instructions.
The OmniBook also requires a special mouse driver for Windows.
Windows 95 Setup will preserve and use this driver when upgrading over
Windows 3.1. If you installed Windows 95 into a new directory
on an OmniBook, then you must copy the HP Obmouse.drv file into the
Windows\System directory, and then change the following lines in your
System.ini file:
[boot]
mouse.drv=obmouse.drv
[386Enh]
mouse=*vmd
DEC Hi Note Ultra
------------------
There are known problems with PCMCIA under older BIOS versions on
this machine. If you encounter difficulties getting your PCMCIA cards
recognized correctly, update your BIOS to a version later than
3/31/95 (v.1.3).
Acer Acernotes
--------------
You may hear a negative (low) tone when you insert the PCMCIA card
after activating the 32-bit PCMCIA drivers. If this happens, remove
the EMMExclude line from the System.ini file and the exclude range
data from the EMM386 line in the Config.sys file. If you still get a
low tone, try carrying out the following procedure:
1. Double-click the PCMCIA icon in Control Panel.
2. Click Global Settings, and make sure Automatic Selection is not
checked.
3. Set the valid range to start at 000D0000 and end at 000DFFFF.
Compaq Aero
------------
The Compaq Aero floppy disk drive is only partially supported by the
Windows 95 PCMCIA drivers. To gain access to the floppy drive,
you need to make sure the card is already inserted when you boot.
After the card has been configured by Windows 95, you can remove and
insert the card normally.
If access to the floppy card still fails:
1. In Control Panel, double-click the System icon, and then click the
Device Manager tab.
2. Click the plus (+) sign next to "Floppy disk controllers."
3. Double-click the floppy disk controller you are having trouble
with.
4. Look at the Device Status area.
5. If it reports a resource conflict, click the Resources tab,
click the "Set Configuration Manually" button, then click OK.
DEC Venturis and Media Vision Audio Cards
-----------------------------------------
There's a known problem with certain combinations of the DEC Venturis
and Media Vision Audio cards.
If you experience problems with this combination:
1. In Control Panel, double-click the System icon.
2. Click the Device Manager tab.
3. Under Sound, Video and Game Controllers, double-click
Media Vision Pro Audio Spectrum 16/Studio With SCSI.
4. Click the Settings tab.
5. Make sure the Enable Warm Boot box is not checked.
Zenith NoteFLEX 486DX and PC cards
-----------------------------------
If your PC cards are not being detected or working properly with the
Windows 95 PCMCIA drivers, follow the below procedure to reserve IRQ
10 and the memory range C000-CBFF.
To reserve resources:
1. In Control Panel, double-click the System icon.
2. Click the Device Manager tab.
3. Click Computer, and then click Properties.
4. Click the Reserve Resources tab.
5. Click Interrupt Request (IRQ), and then click Add.
6. Reserve IRQ 10, and then click OK.
7. Click Memory, and then click Add.
8. Reserve the memory range C000-CBFF, and then click OK.
9. Click OK again, and then restart your computer.
Zenith NoteFLEX 486DX and Flexshow docking station
--------------------------------------------------
If you are using the NoteFLEX with the Flexshow docking station, you
must reserve IRQ 10 so that the built-in CD-ROM drive will work. To
do this, follow the above procedure and only reserve IRQ 10.
In your Config.sys file, make sure the line loading Mztinit.sys
appears before the line loading PCenable.exe or your computer will
stop responding during startup.
Also, to avoid numerous "Bad Command or File Name" errors during
startup and to ensure the computer is configured properly, copy
Rplstr.com from your \Dos directory to your \Windows directory.
Zenith NoteFLEX 486DX and PCMCIA hard drives
--------------------------------------------
If you are using a PCMCIA hard drive with this computer, you must
enable 32-bit PCMCIA support in order to access the drive.
To enable 32-bit PCMCIA support:
1. In Control Panel, double-click the PC Card (PCMCIA) icon.
2. Follow the instructions on your screen.
If you see properties for your PCMCIA socket instead of the wizard,
Windows 32-bit support for PC cards is already turned on. If you do
not see the PC Card (PCMCIA) icon in Control Panel, double-click the
Add New Hardware icon in Control Panel to install your PCMCIA socket.
Megahertz Em1144T and 16-bit Modem
----------------------------------
If you experience problems setting up the modem side of this card
in a real-mode PCMCIA environment, try explicitly setting the COMIRQ
and COMBASE parameters in the Megahertz section of your Protocol.ini
file. There is a known problem where this card enabler ignores the
default values set for these parameters.
Digital Venturis (any model)
----------------------------
If PNPISA and/or PCI cards are not automatically recognized, or if
Windows generates Blue Screen errors when reconfiguring your COM
ports, contact Digital for a new BIOS.
Printing from Device Manager
----------------------------
If you choose to print "all devices and system summary" from Device
Manager, the device detection code MAY cause problems for MS-DOS-
based programs. The symptom of this problem is that after you print,
your computer reports that it is out of memory when you try to run
an MS-DOS-based program. When this problem occurs, you may need to
restart Windows to correct the problem.
Mozart Sound Card/Canon Innova 550 CD Driver Problem
----------------------------------------------------
You may experience problems when you start up Windows 95. To receive
a new driver that works with Windows 95, contact the Canon Help Desk.
Users of TrueFFS Flash File System for PCMCIA Cards
---------------------------------------------------
The MS-DOS or Windows 3.1 versions of the TrueFFS driver will not work
with the Windows 95 PCMCIA driver. To work with FTL formatted Linear
Flash PCMCIA cards when the Windows 95 PCMCIA driver is enabled, you
must install a new Windows 95 device driver provided by M-Systems. To
do this, carry out the following procedure:
1. In Control Panel, double-click the Add New Hardware icon.
2. Click Next, and then click the option not to have Windows search
for your new hardware.
3. Click Hard Disk Controllers, and then click Next.
4. From the list, click M-Systems.
5. Click the specific Flash Card, and then click Next. Then follow
the instructions on your screen.
NOTE: If M-Systems is not shown in the list, click Have Disk, and then
insert the M-Systems Windows 95 installation disk and follow the
instructions on your screen.
Micronics Motherboards with a Flash BIOS
-----------------------------------------
Before installing Windows, users of Micronics motherboards with a
Flash BIOS need to be sure the BIOS read/write jumper is set to the
read-only position. If you try to install Windows 95 with this jumper
in the read\write position, it may cause BIOS corruption. For more
information, contact your computer manufacturer.
Toshiba Computers: T610 T400 series, T2100 series, T2400 series,
T4700 series, T4800 series, and the T4900CT and T3600
----------------------------------------------------------------
If you use any of these Toshiba computers, Toshiba strongly recommends
upgrading your computer's BIOS to version 5.0. The upgraded BIOS
provides additional functionality for the Windows 95 operating system.
For more information, in the United States contact Toshiba at
(800) 999-4273. Outside the U.S., contact your local Toshiba dealer.
Toshiba T2150 models
---------------------
If your system stops responding during suspend or resume operations,
comment out the line that loads the Toscdrom.sys driver from your
Config.sys file. For example:
rem device=c:\cddrv\toscdrom.sys
Sanyo 3-D ATAPI (IDE) CD-ROM drive
----------------------------------
The Sanyo 3-D ATAPI (IDE) CD-ROM drive uses a proprietary scheme to
support the three-disk changer. Although all three drives will appear
when you are running in protected mode, only one of them will be
accessible.
To regain access to all three drives, remove the REM command from the
beginning of the MSCDEX line in your Autoexec.bat file. You also need
to disable the Windows 95 protected-mode disk driver. To do this,
carry out the following procedure:
1. Click the Start button, and then point to Settings.
2. Click Control Panel, and then double-click the System icon.
3. Click the Device Manager tab.
4. Click View Devices By Connection.
5. Click plus signs next to devices until you find the Sanyo drive.
6. After you find the Sanyo drive, look at the levels above it
until you find the parent controller.
7. Click the controller, and then click Properties.
8. In the Device Usage area, clear the check box next to the current
configuration.
This will enable access to all three drives from Windows 95 protected-
mode; however, your disk, CD, and any other devices under the
controller will be accessed only through real-mode drivers.
For information about updating your driver to a Windows 95 driver,
contact your hardware vendor.
Micron PowerServer M5-PE (66 MHz Pentium PCI/EISA bus)
-------------------------------------------------------
The BusLogic BT-946C PCI SCSI adapter may not be compatible with
Windows 95. If you encounter difficulties with your SCSI peripherals,
contact Micron to determine whether you need an updated adapter.
SCANNERS
========
Windows 95 will detect most scanner hardware, but does not supply
protected-mode drivers for any scanner model.
All SCSI scanners use a feature called ASPI to talk to the controller
in question. Windows 95 supports ASPI in protected mode. Hence, a
scanner, although listed as an "unknown device" in Device Manager, is
supported through protected-mode drivers in Windows 95, if there is a
protected-mode driver for the SCSI controller in question.
Note that theoretically you would not need the ASPI manager real-mode
driver (such as Aspi2dos.sys) in your Config.sys file. However, some
programs, such as HP ScanJet II and its associated real-mode drivers,
Sj!!.sys and Sjiix.sys, require the real-mode ASPI manager to be in
the Config.sys file or they will fail to load. In these cases, you
would need to keep the real-mode drivers in the Config.sys file, but
Windows 95 will still support the scanner through the protected-mode
SCSI miniport driver (if one exists for the SCSI controller in
question).
Logitech Scanman
----------------
If you use a handheld Logitech Scanman on a computer that has more
than 16 MB of memory, you may see the following message: "Insufficient
system resources." To resolve this problem, you can obtain an updated
driver, Scanupt.exe, from the Logitech bulletin board or from
CompuServe.
MODEMS
======
Modems Control Panel
--------------------
In order to use your modem with the built-in communications features
of Windows 95, including HyperTerminal, and Dial-Up Networking, your
modem must be configured in Modems properties in Control Panel.
Settings made in Modems properties do not affect modem operation in
programs designed for MS-DOS or Windows 3.1.
Modem Detection
---------------
If Windows 95 detects your modem as a "Standard Modem," or incorrectly
detects its make and model, you can use the Change button in the
Install New Modem wizard to make a different selection. However, if
you manually select an incorrect type, your modem may not to work with
Windows 95 communications features. If this happens, double-click the
Modems icon in Control Panel, remove the modem, and then add it back
as one of the Standard modem types.
When configured for "Standard Modem," Windows 95 will use your modem
with its factory default settings. The modem will make optimal high-
speed connections with Windows 95 communications features. However,
you will not be able to adjust some of the modem's settings, such as
speaker volume and cellular protocols.
Racal Modems
------------
If you have a Racal modem, do not use detection in the Install New
Modem wizard. Instead, click Don't Detect My Modem, and then pick one
of the standard modem types. If you have already run detection and
your modem is not responding, turn the modem off and then back on
again.
Minitel (France)
----------------
Some modems may not be able to connect to French Minitel in
HyperTerminal by using the Windows 95 default settings. To correct
this, carry out the following procedure:
1. Check your modem manual for a command that will enable your modem
to connect in V.23 modulation to Minitel.
2. In Control Panel, double-click the Modems icon, click the name of
your modem, and then click Properties.
3. Click the Connection tab, and then click Advanced.
4. In the Extra Settings box, type the command.
TAPE DRIVES
===========
Tape Drive Detection
--------------------
Plug and Play software does not detect tape drives. As a result, the
only tape drives that appear in Device Manager are SCSI tape drives,
which appear as either an unknown device or a tape drive.
However, most backup programs do detect tape drives, so don't be
concerned if your tape drive does not appear in Device Manager. If
your backup software does not detect your tape drive, contact the
company that wrote the software.
Tape Drive Compatibility
------------------------
Microsoft Backup works only with the 1992 or later versions of the
tape drives listed below. If your tape drive does not appear in the
list below, contact your tape drive manufacturer for information about
backup software that you can use with Windows 95.
