Welcome to Adaptec EZ-SCSI Standard Edition v5.0c
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
This readme contains information on the following for
Windows 95, Windows 98 and NT:
A.) Help on installing Windows 95 from a SCSI CD-ROM
B.) Help on installing NT on a SCSI hard drive
C.) Installing Host Adapter Drivers (also called miniports)
D.) Specific Host Adapter Driver Tips
A.) Help on Installing Windows 95 from a SCSI CD-ROM
====================================================
1. Install EZ-SCSI for DOS from the EZ-SCSI for DOS/Win 3.1x
diskette. All the drivers needed to access your CD-ROM drive will
be loaded in config.sys, and you will be able to install Windows 95.
(This of course assumes you had DOS already loaded on your
system so that EZ-SCSI could load MSCDEX. If this file
is not available you will be prompted for it by EZ-SCSI)
2. Take note of the lines containing aspi*dos.sys and aspicd.sys
in config.sys, and MSCDEX in autoexec.bat.
3. Install Windows 95
4. Say yes when it asks you should it create an emergency
repair diskette for you.
5. When installation is complete you should copy the lines
noted in step 2 above into config.sys and autoexec.bat
on this emergency diskette. This disk will allow you to
reboot your system in an emergency and access your CD-ROM to
restore Windows 95.
B.) Help on Installing NT on a SCSI hard drive
==============================================
If you do a floppyless install of NT 3.51 from
your SCSI CD-ROM using winnt /b, you may run into
a blue screen the first time the NT Installer
reboots your system. The reason for this is the
installer cannot find your SCSI hard drive.
You must reboot again, and just after the banner for
NT appears, you have 2 seconds within which to
press F6. This will pop up the screen that allows
you to specify your SCSI host adapter. You should
specify Other and insert the EZ-SCSI Drivers Disk
when prompted. Then continue with the rest
of the installation.
This trick is also useful if you want NT to use the host adapter
driver provided on the EZ-SCSI Drivers Disk instead of the older
drivers included in the O/S.
C.) Installing Host Adapter Drivers (also called miniports)
===========================================================
What is a SCSI miniport? A SCSI miniport is a device driver that
controls your SCSI host adapter. For example, if you are running
Windows 95 with an Adaptec AHA-2940, the miniport driver you are
using is named aic78xx.mpd. Windows 95, Windows 98 and NT come with
embedded drivers for most of Adaptec's host adapters. Included in
disk 1 of EZ-SCSI Standard Edition are newer Adaptec miniports.
=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-
Automatic Installation by EZ-SCSI
=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-
When you run the EZ-SCSI Installer from the disk 1, it will
automatically determine if the miniport driver included on disk 1
is newer than what you already have installed on your system.
If it is, your installed miniport driver will be automatically updated
with the newer version. After EZ-SCSI completes its installation it
will reboot your computer. Upon reboot, if your system doesn't yet
see your host adapter, you will need to take one of the following sets
of steps, to complete the installation of the miniport driver on your
system. The usual cause of this is a non plug and play host adapter,
or a non plug and play OS, such as NT 3.51 or 4.0.

Known Issues for Windows 98
=-=-=-=-=-=-=-=-=-=-=-=-=-=
o Some Windows 98 users may receive the following error message during
the EZ-SCSI Deluxe installation process:
"Could not write to the file named: 'C:\WINDOWS\SYSTEM\wininet.dll'.
The file is currently being used by another application.
Please shut down your other applications.
Abort, Retry, Ignore"
Select "ignore" and disregard this message.
Under Windows 98 systems, The file wininet.dll is always open and
can not be overwritten. All Windows 98 systems already include a
copy of this file.
=-=-=-=-=-=-=-=-=-=-=-=-=-=
Known Issues for Windows 95
=-=-=-=-=-=-=-=-=-=-=-=-=-=
o The mapping between mscdex, which runs in real mode, and the
Windows 95 CD-ROM driver does not match. You can correct this in
one of two ways:
1 Comment out the line that loads mscdex.exe in the autoexec.bat
file.
2 Change the /L switch on the line that loads mscdex.exe in the
autoexec.bat file so it assigns the CD-ROM drive the next highest
logical drive letter after the hard disk drives.
o Windows 95 does not support sharing of system interrupts (also
known as IRQ's) between two or more I/O subsystem devices (i.e.
network interface cards or hard disk adapters such as SCSI host
adapters). When IRQ's are shared between I/O devices, lockups can
occur while booting. If lockups occur, try moving or removing one
or more PCI cards from one slot to another and bootup your computer
again. If problems continue, refer to your system documentation
and/or your system technical support for information on adding
your system configuration.
o In some cases, each channel of a MultiChannel adapter must be
updated/installed manually with the aic78xx.mpd driver on a
freshly installed Windows 95 system. Please follow the
instructions listed under "Manually Updating your Driver" for each
channel.
=-=-=-=-=-=-=-=-=-=-=-=-=-=
Known Issues for Windows NT
=-=-=-=-=-=-=-=-=-=-=-=-=-=
o For Windows NT v3.5x, the embedded (included) miniport driver on the
NT CD-ROM or diskettes, does not include support for Ultra host
adapters (i.e., host adapters with the letters AU, U, UW, AUW, and
AUWD at the end of the model number) and AHA-2944W. Refer to the
installation instructions in section d) above.
o For Windows NT v4.0, upto and including Service Pack 3, the embedded
(included) miniport driver on the CD-ROM does not include support
for AHA-3940AUWD, AHA-3944AUWD, or AHA-4944W. Refer to the
installation instructions section d) above.
o An issue exists in Windows NT 3.5x with the Windows NT Setup
Application. In the Add/Remove SCSI Adapters selection, under the
Options pull-down menu, you should see:
"Adaptec AHA-294x/AHA-394x/AHA-4944 or AIC-78xx PCI SCSI Controller
(NT 3.5x)"
and possibly one or more of the following
"Adaptec AHA-294x/AIC-78xx (PCI)"
"Adaptec AHA-2940/AIC-78xx (PCI) NT v3.5x"
"Adaptec PCI SCSI Controller(NT 3.5) AHA-290x/291x/294x/394x/4944/AIC-78xx"
as listed choices. This behavior is due to differences between
the embedded SCSI.INF file and the OEMSCSx.INF that was created when
installing/updating the aic78xx.sys. All of these choices, refer to
the same Adaptec aic78xx.sys driver in your system.
Removing any one of them, without the intention of either replacing
or upgrading, may result in your system failing to boot.
o If disconnection is disabled under SCSISelect for a hard disk device,
the system may hang if the hard disk device supports tagged queuing.
It is recommended to always enable disconnection for hard disk
devices. By default, disconnection is enabled so no action is
required. If for some unique requirements disconnection has to be
absolutely disabled for hard disk devices, you can turn off tagged
queue requests by editing the Windows NT Registry. You can do so
by following these instructions:
1 Select Run from the File pull-down menu (Windows NT 3.5x), or Run
from the Start button (Windows NT 4.0).
2 Enter REGEDT32 to run the Registry Editor.
3 a. For non-Ultra2 host adapters:
Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aic78xx.
b. For Ultra2 host adapters:
Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aic78u2.
4 Create a key named Parameters by selecting Add Key from the Edit
pull-down menu and entering "Parameters" (without quotations) in
the edit-box for Key Name. Leave the Class edit-box blank.
5 Open Parameters and create a key named Device by selecting Add Key
from the Edit pull-down menu. Enter "Device" (without quotations)
in the Key Name edit-box. Leave the Class edit-box blank.
6 Open Device. Select the Add Value option from the Edit pull-down
menu. In the Value Name edit-box, enter "DisableTaggedQueuing"
(without quotations). Select the Data Type REG_SZ from the
droplist combo box.
7 Shutdown and restart Windows NT.
8 Set Enable Disconnection to No for your particular device(s) in
SCSISelect during bootup. (See your Host Adapter manual on how to
use SCSISelect).
o If the logical driver letters assigned by the BIOS change when the NT
operating system is running, it's not an error. To preserve drive
letter assignments between BIOS and NT, run the NT disk administrator
and choose permanent drive letters assignments as an option. NT will
then preserve logical drive letter assignments across boots and
adapters.
o The boot manager for Windows NT contains recovery logic to allow you
to return to the last known good configuration. If you have changed
your host adapter configuration and Windows NT no longer boots, follow
these steps to recover:
1 Undo any hardware changes you have made to the computer since it was
last operational.
2 Reboot the computer. Watch the display carefully during bootup. If
the following message appears, press the Spacebar.
Press spacebar NOW to invoke the Last Known Good menu
Follow the instructions on the screen to continue booting with the
last known good configuration. For Windows NT 4.0 only, hit the
letter "L", to switch to the last known good configuration.
3 Once your computer is operational again, check all of the hardware
and software configuration changes you want to make. Look
specifically for conflicts with parts of the existing system
configuration that are not being changed.
