If I am running under Windows95, do I need lines for the Adaptec real mode

ASPI drivers and mscdex in my CONFIG.SYS and AUTOEXEC.BAT files? Usually, you do not need to use these real mode ASPI drivers, because the new Windows miniport drivers support most SCSI host adapters and SCSI devices. How- ever, you need to load the drivers (including mscdex, if you have a CDROM drive) if any of the following is true:

•You are running in MSDOS mode

•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 CDROM drive that Windows95 does not support

•You are using a CD-Recorder drive (however, some newer models of CD- Recorder drives can use the embedded Windows miniport drivers)

To install the Adaptec EZSCSI DOS drivers, click the Start button and select Restart the computer in MS-DOS mode. When the DOS prompt appears, follow the Quick Start instructions for DOS.

My CD-ROM drive doesn’t work properly under Windows95.

Some older models of SCSI CDROM drives are not compatible with the embedded Windows95 CDROM driver. You can add support for the CDROM drive by doing the following:

1.Click the Start button and select Restart the computer in MS-DOS mode.

2.When the DOS prompt appears, follow the Quick Start instructions for DOS.

3.When you are finished running Adaptec EZSCSI for DOS, find the file named cdtsd.vxd in the windows\system\iosubsys directory and rename it cdtsd.sav.

My CD-ROM drive shows up as more than one icon under My Computer.

The mapping between mscdex, which runs in real mode, and the Windows95 CDROM 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 CDROM drive the next highest logical drive letter after the hard disk drives.
