Thinkstation S30 old driver 42A

Hi,

I was trying to install Win10 on the ThinkStation S30 and for that I changed the BIOS configuration. Result!

The PC doesn't start and Beeps. I troubleshoot the problem by the sound and it has to do with the Video card being incompatible with the UEFI configuration.

So I removed the battery from the Motherboard... didn't result.

I tried to reset the BIOS changing the CMOS pin to the reset position... didn't result.

So I downloaded the BIOS driver (ISO) and installed in the USB and run... it runs but it shows an error saying that the BIOS on the system is too old and first I need to use the same version or older. So the version that I have is the 42A.

In short, where can I find this version or lower of the BIOS for the S30 (4351)?

Thank you very much for the support.
