Hello,

Is it with PCU20 or PCU 50?

Does your system boot completes? Is your machine working correctly? What other alarms/faults are displayed?

 Is MMC103

Yes after the driver request I press continue and the system boot completely and everything run OK, no other alarms present.

Thanks

 You have old MMC103 with OS Win 95, but you did not show the picture of the back of the MMC. I just think your MMC connected an option to PCI slot. such as network interface. 

If that is true, you need to remove it 

This is the back of my MMC103, I don't see any hardware added compared to another machine very similar I own that doesn't have the same driver request issue.

Thanks.

I found this but doesn't solve the problem

Problem solved, I used a little software to identify the right device, found drivers and installed.

The device is Intel PCI-USB controller, but I still don't see where it is physically located, very strange.

Thanks.
