Hi!

I tried posting this once before. I have more info now, so I will try again....

I work for an organization that takes in donated PC's in order to refurbish them for return to underprivileged communities. We recently received a stock of old Aquanta DL series 2 machines (CWP 50034). They have LAN NIC's installed + the on-board LAN. We would like to remove the installed NIC's and use the on-board LAN. This is where the problem is. We can not get the on-board LAN to enable and work. No jumpers on the motherboard. Nothing in BIOS. All current drivers for Crystal CS8900/CS8920 installed. No conflicts. All other network adapters removed.

Under properties it says "This device is either not present, not working properly, or does not have all the drivers installed. (code 10)". What could we be missing? Any suggestions would be great. Thanks!

It is possible that the on-board LAN adapter was damaged at the site where these PCs used to be, and that is why they all have LAN cards.

It is also possible that a left-over registry setting, or system file from the plug-in LAN cards is preventing the on-board LAN from initializing.

The simple way would be to pick 1 system, and perform a clean install of the OS onto a formatted hard drive.

If the on-board LAN still does not work, then the ports are likely damaged.

If it works, thenyou need to find the registry settings, and system files that are getting in the way.
In the registry, start with the enum key.

You say you have tried the latest drivers for the chips.
Have you located the motherboard / system manufactures drivers?
Sometimes, they "customize" the driver code for their application.
The mfg driver may have code that enables a "hidden" BIOS switch.
