Debugging Mode
VMware Workstation can run in two modes — normal mode and a mode that
provides extra debugging information. The debugging mode is slower than normal
mode.
For normal use, check to be sure you are not running in debugging mode. Go to Edit
> Virtual Machine Settings > Options and select Advanced. In the Advanced
Options section, be sure there is no check in the Run with debugging information
check box.
CD-ROM Drive Polling
Some operating systems — including Windows NT and Windows 98 — poll the CD-
ROM drive every second or so to see whether a disc is present. (This allows them to
run autorun programs.) This polling can cause VMware Workstation to connect to the
host CD-ROM drive, which can make it spin up while the virtual machine appears to
pause.
If you have a CD-ROM drive that takes especially long to spin up, there are two ways
you can eliminate these pauses.
• You can disable the polling inside your guest operating system. The method
varies by operating system. For recent Microsoft Windows operating systems,
the easiest way is to use TweakUI from the PowerToys utilities.
For information on finding TweakUI and installing it in your guest operating
system, go to www.microsoft.com
depend on your operating system.
• Another approach is to configure your virtual CD-ROM drive to start
disconnected. The drive appears in the virtual machine, but it always appears to
contain no disc (and VMware Workstation does not connect to your host CD-
ROM drive).
To make this change, go to Edit > Virtual Machine Settings. Click the DVD/CD-
ROM item in the Device list. Then clear the Connect at Power On check box.
When you want to use a CD-ROM in the virtual machine, go to the Edit >
Removable Devices menu and connect the CD-ROM drive.
