PC Magazine CD and Helper Applications:
==================================

Netscape HTML browser:

==================================
PC Magazine CD and Internet Access:
==================================
PC Magazine CD comes with Netscape Navigator 2.01 and the CompuServe WinCIM dialer. You may use
the version of Netscape included on the CD with an internet service provider (ISP) other than
CompuServe. In order to do this, select "I already have an internet connection." In the appropriate dialog box during the Netscape installation. Copy the version of Winsock that is used by your ISP to the Windows, Win95, or CServe\Netscape folder in order to automatically access your ISP from Netscape.
==================================
PC Magazine CD and Memory Issues:
==================================
The core functions of PC Magazine CD will work on systems with 8MB of RAM.
However, you may find that some functions, particularly ScreenDemos, video clips, and Director
movies, require more memory to run. If you are working on an 8MB system, creating or
increasing the size of your Windows Virtual Memory swap file (available under the Windows 386
Enhanced section of the Control Panel) to a minimum of 6MB should allow you to view these
advanced functions. Increasing the size of your swap file to 10MB will significantly enhance
performance.
You may also launch sub-applications from PC Magazine CD directly to free additional memory.
For example, to view the ScreenDemos from our reviews, open Windows' File Manager
and change to your CD-ROM drive, open the directory named SDEMOS, and
double-click on any executable file (*.EXE).
If your system has less than 475K of DOS-mode RAM, you may experience problems running the shell
application, or the ScreenDemos. Unloading one or more drivers (network, TCP/IP, etc.) before loading
Windows and launching PC Magazine CD should fix this problem.
On machines running Windows 95, we suggest you close all other applications to get optimal performance
from PC Magazine CD.
=====================================
PC Magazine CD ScreenDemos and Audio:
=====================================
PC Magazine CD includes a number of ScreenDemos, which are product demonstrations that
incorporate a series of screens from Windows applications along with an audio track. If your
system does not have a Windows-compatible sound system, you will be able to play the
ScreenDemos, but you will not hear the audio portion of the demonstration. In some instances, if
you do not have a Windows-compatible sound system, you may see an error message the first
time you attempt to run a ScreenDemo. However, after the initial effort, ScreenDemos should
run normally.
Some users have experienced problems with the audio portion of ScreenDemos when using systems
equipped with Ensoniq sound boards. If you use an Ensoniq sound board and do not hear the audio track
on when you play a ScreenDemo, the following procedure should help you get the sound to work:
1. Enter the Windows Control Panel and select Drivers.
2. In the drivers list, look for the SoundScape DVD midi, wave, aux driver. Select this driver and
click on the Setup button.
3. The top of the setup window should contain settings for the Primary Wave With Port and
Channel settings. Typically, the primary wave is set to DMA channel 1. The lower part of the
window should be settings for the secondary wave. Typically, wave A and wave B are disabled.
4. Enable both wave A and wave B, and give them DMA channels 0 and 3 respectively. The
primary wave and the secondary waves must have different DMA channel settings.
5. Quit and restart Windows.
6. The sound driver should now be set up properly, and you should be able to hear sound from
the CD ScreenDemos.
===========================
PC Magazine CD and ScreenCam
===========================
The following is a list of tested video drivers and the results Ziff-Davis Labs has produced using
ScreenCam (please note: this list is not exhaustive; your results may vary). If you are having problems
running ScreenCam, please make sure that your screen's bit depth is set for at least 8-bits (256 colors.)
Note: Some users have experienced pallette shifts when viewing ScreenCam demonstrations. If your
system supports more than 256 colors, increasing the color bit depth should allieviate this problem.
Board Driver Name Driver Version Driver Date File Size
(bytes)
ATI Graphics Ultra Pro MACH.DRV 3.1 4/25/94 277,520
(Mach 32 ISA)
Comments:
With 256 color pallette on, ScreenDemos break up, sometimes hang. With 256 color pallette off, runs fine.
