Installation Instructions

If you are performing a first time Windows 95 installation, see the "Installing the Driver When Installing Windows 95" section, below. If Windows 95 is already installed on your system, see the "Updating the Driver for Windows 95" section. For more complete instructions, the Ultra160 FMS User's Guide is available online. Please see the support section at http://www.adaptec.com/support/ .

NOTE: Windows 95 shipped in two different version - the Retail Edition and the OEM Service Release 2 (or OSR2) Edition. Both versions function the same, but the process of installing drivers is different.

To determine which version you have, follow these steps:

1. Select Control Panel under Settings from the Start Menu.
2. Double-click the "System" icon.
3. Under the "General" tab, it will display the version number of Windows 95 under the System category.
4. If it displays "4.00.950", you have the Retail Edition installed. If it displays "4.00.950 B" or "4.00.950 C", you have OSR2.x installed.

Installing the Driver When Installing Windows 95

Note: Follow the Windows 95 installation manual to install Windows 95. If your Windows 95 CD came with a Windows 95 Boot Diskette, you will need to update the Windows 95 Boot Disk. Copy the file ASPI8U2.SYS and ASPICD.SYS from the DOS directory of the Adaptec Ultra160 Family Manager Set driver diskette to the Windows 95 Boot Disk. Refer to the sections "Update Windows 95/98 installation diskettes" and "Install CD-ROM drivers on a DOS bootable diskette or hard drive" under "DOS Drivers for CD-ROM Access" if you are unsure how to do this.

1. If "New Hardware Found" is displayed, select "Driver from disk provided by hardware manufacturer".

2. Insert the Adaptec Ultra160 Family Manager Set diskette into the floppy drive and type a:\win95 as the path; follow the on-screen instructions.

3. If you are prompted to reboot the system, select "no" if you have a dual channel adapter or if you have multiple Ultra160 adapters. Then repeat steps 1 through 3 for each SCSI channel until all Ultra160 adapters are found. Otherwise, select "Yes" to reboot the system.

NOTE: If you do not see "New Hardware Found", you might need to add the driver manually. Once Windows 95 is installed, follow the steps in the section titled "Updating the Driver for Windows 95 (Retail Edition)" or "Updating the Driver for Windows 95 (OSR2.x)" to verify that the drivers have been added and are working properly. If a yellow question mark labeled PCI SCSI Bus Controller is displayed, update the driver as described.

Updating the Driver for Windows 95 (Retail Edition)

To update or install the ADPU160M.MPD driver if Windows 95 is already installed, follow these instructions:

1. Start Windows 95.

2. Click the Start button on the Windows 95 task bar, and then point to Settings.

3. Click Control Panel.

4. Double-click the System icon.

5. On the Device Manager tab, click the plus sign next to the SCSI controller icon.

NOTE: If Windows 95 cannot determine the type of host adapter installed in your computer, a yellow question mark labeled Other devices appears instead of the SCSI controller icon. To continue, click the plus sign next to the question mark; a yellow question mark labeled PCI SCSI Bus Controller then appears.

6. Double-click the Ultra160 Family host adapter you wish to update, or if a yellow question mark labeled PCI SCSI Bus Controller is displayed, double-click the question mark.

7. Insert the Adaptec Ultra160 Family Manager Set Diskette into drive A:.

8. Select the Driver tab.

NOTE: If the version of Windows 95 you are using now displays a window with a Update Driver button instead of a Change Driver button, the remainder of your install procedure is covered in Updating the Driver for Windows 95, Version OSR 2.x, described below.

9. Click Change Driver. You may be asked to select the hardware type; if so, select SCSI Controllers.

10. Click the Have Disk button and enter a:\win95 as the path.

11. Click OK.

12. Select the Adaptec Ultra160 Family host adapter, and click OK.

13. Again, click OK. The driver is now installed.

14. You must restart your computer for the changes to take effect. Click Yes to restart your computer. Click No to return to the system properties window.

Updating the Driver for Windows 95 (OSR2.x)

This section covers the remaining steps to updating the driver on Windows 95 OSR2.x.

NOTE: If you have not already done so, follow the instructions in "Updating the Driver for Windows 95" section above.

1. Click Update Driver.

2. Insert the Adaptec Ultra160 Family Manager Set diskette into drive A:.

3. In the Update Device Driver Wizard, select Yes, and click Next.

4. Select Other locations.

5. Under the Location edit box, type a:\win95, then click OK.

6. Click the Finish button.

7. At the message "Please insert the disk labeled 'Ultra160 Family Manager Set Installation Disk'", insert the Adaptec Ultra160 Family Manager Set diskette for Windows 95 and click OK.

8. Another dialog box, Copying Files, appears with the message "The file 'ADPU160M.MPD' on Ultra160 Family Manager Set Installation Disk could not be found ...". Type a:\win95 in the Copy Files from the edit box and click OK. The driver is now installed.

9. You must restart your computer for the changes to take effect. Click Yes to restart your computer. Click No to return to the system properties window.

NOTE: If you attempt to re-update the driver again, at step 3 above you will need to select No, click Next, and follow the on-screen instructions to re-update.

Known Issues

In some cases, each channel of a multichannel adapter must be updated/installed manually with the ADPU160M.MPD driver on a freshly installed Windows 95 system. Please follow the instructions listed under "Updating the Driver for Windows 95" for each channel.
You will need to load the ASPI drivers (including MSCDEX.EXE, if you have CD-ROM drive) if any of the following are true:

You are running in MS-DOS mode and need to access your CD-ROM drive.
You are using a scanner or another SCSI device with CONFIG.SYS or AUTOEXEC.BAT based drivers, such as HP's SJIIX.SYS.
You have an older model SCSI-1 CD-ROM driver that Windows 95 does not support.
You are using a CD-Recorder drive (however, some newer models of CD-Recorder drives can use the embedded Windows drivers).

Some older models of SCSI CD-ROM drives are not compatible with the embedded Windows 95 CD-ROM driver. You can add support for the CD-ROM drive by doing the following:

Make sure your ASPI real mode drivers (including ASPI8U2.SYS, ASPICD.SYS and MSCDEX.EXE) are loaded and running from your CONFIG.SYS and AUTOEXEC.BAT files.
If the first step did not work, find the file named CDTSD.VXD in the \windows\system\iosubsys directory, rename it to CDTSD.SAV and reboot your system.

The mapping between MSCDEX.EXE, which runs in real mode, and theWindows 95 CD-ROM driver does not match. You can correct this in one of two ways:

Comment out the line that loads mscdex.exe in the autoexec.bat file.
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.

Windows 95 does not support sharing of system interrupts (also known as IRQs) between two or more I/O subsystem devices (i.e. network interface cards or hard disk adapters such as SCSI host adapters). When IRQs 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.
Certain older hard drives (Ultra-SCSI and lower) do not meet certain SCSI timing requirements, and can cause the operating system to fail to boot. It is recommended that the firmware on the hard drive is updated or the drive is moved to the Fast/Wide segment (SE connector) on the host adapter where the commands of these drives can be buffered.
