TB146 Rev1 Windows 98 Installation
Overview
Although not recommended or supported by Centroid it is possible to install Windows 98 on a Centroid
control as long as it meets the minimum hardware requirements set by Windows
During installation on a control that uses an Acrosser motherboard certain software problems can occur The
condition is normally be indicated by "Blue Screens of Death" or the control locking up This is caused
because Windows will not install some of the hardware device driver files correctly specifically the
VMM32 VXD file The problem can be resolved by manually extracting the files from your Windows 98
installation CD
Testing
You must first check to see if your system is using the correct driver files The procedure for this is as follows
1 From Windows go to Start Settings Control Panel System Device Manager System
2 Highlight the Properties
for System Board
and select Driver Driver File Details
3 If you see C \Windows\System\vmm32 vxd configmg vxd
then your Windows installation is using the
wrong file and you will need to follow the instructions below on extracting the correct one
4 If the driver is correct it should read C \Windows\System\configmg vxd
Below is a complete list of all the drivers that may not be installed correctly
Communication driver vcomm vxd
Video drive device vdd vxd
Video frame rate buffer virtual device vflatd vxd
DMA controller driver vdmad vxd
Mouse driver vmouse vxd
Motherboard configuration manager configmg vxd
Kernal driver for the universal host controller ntkern vxd
Solution
If you have determined that your machine is using the incorrect driver files you must install the correct VXD
files These files will be located in the CAB files on the Windows 98 Install CD
If you are running Windows 98 then the configmg vxd
file is in the Win98_47
CAB file and the rest are in the
Win98_48
CAB file Under Windows 98 SE the files are in the Win98_53
and Win98_54
CAB files All the
CAB files are located in the Win98
directory on the CD
To extract the files simply right click on the files and select Extract You will be prompted for the directory to
extract them to Extract all files to C \Windows\System
Once all the files have been extracted you must reboot the machine Upon restarting please check to
ensure the correct VXD files are now being used
If you do not have the Windows 98 CD please contact Centroid Tech Support and we can provide the
needed VXD files
