The video driver for my system won’t install correctly. I have a Celeron 566 based on Protac M754 lmr motherboard and I run Windows 2000 Professional. This motherboard is a 4-in-1 type in that it has on-board sound card, video card, modem and network card. I use the supplied CD-ROM for the motherboard to install all the necessary drivers for the various devices. When I go through Device Manager and use this CD-ROM to try to install the recommended and detected video driver for nVidia Aladdin TNT 2, the installation stalls with the appearance of the message ‘The file ‘nv4_mini.sys’ on NVIDIA NT Driver Library Installation Disk 1 is needed’. I point Device Manager to the relevant folder and file but it keeps coming up with the message above. Previously the video driver was installed but it crashed after I tried to play a DVD on my PC. After rebooting, the screen was in disarray so I went into Enable VGA Mode in the Advanced Options Menu during the boot-up process and uninstalled the suspect video card. The computer then booted up normally but with only the basic VGA settings. I can’t play games or view graphics at the moment though I can use the PC for a basic workstation. Protac’s web site has some updates on the Protac M754 lmr BIOS but I haven’t found anything useful. A second, but less urgent, problem is when trying to install the SiS 900 PCI Fast Ethernet Adaptor, an error occurs during installation, where it cannot find a requested line in INF file. Any help would be appreciated.

After looking around the internet it appears that others are experiencing the same problem as yourself. These people used a particular method to install their drivers but I am not sure if it would work for you. In any case, the first step is to download the latest nVidia Detonator Drivers from the internet. These drivers utilise Unified Driver Architecture which means that one driver binary supports all products. You can download the latest drivers from www.nvidia.com/view.asp?PAGE=dri0vers. Once you have downloaded these drivers, try installing them to see if it works. If not, then try the following procedure. Copy the directory containing the drivers from the CD-ROM supplied with your machine. Open the nv4_disp.inf file in a text editor (eg. Notepad). Find and DELETE the lines:
[SourceDiskNames]
1 = %DiskId%, disk1
2 = %DiskId%, disk2

[SourceDiskFiles]
nv4_mini.sys = 1
nv4_disp.dll = 1
nvinstnt.dll = 1
nvoglnt.dll = 2

Next, find and REPLACE the two lines:
DiskId1= ‘NVIDIA NT Driver Library Installation Disk 1′
DiskId2= ‘NVIDIA NT Driver Library Installation Disk 2′
…with:
DiskId= ‘NVIDIA NT Driver Library Installation Disk’

This should fix the problem if it is caused when the installation program becomes confused about the INF file, expecting to see two disks whereas there is in fact only one. Try reinstalling the drivers through the same procedure, as you would if installing off the CD-ROM but instead, point Device Manager to the directory on your hard drive containing the drivers and customised nv4_disp.inf file.

Regarding your second problem, I would not bother installing the adapter if you don’t have a network, as it would be simply taking up system resources for no reason. However, in future, if you do have a network and wish to install the adapter, I suggest that you download the drivers from www.sis.com/support/driver/index.htm. Seemingly, the drivers, in particular the INF file on the CD are corrupt, since a required line in the instructions file (INF file) needed to install the drivers can’t be found.
