Hello, i'm new here.
So i was trying to figure this out 2 years ago.
So i have an old Asrock N68C-S-UCC motherboard with a single-core AMD Sempron 140.
Whenever i try to enable the ASROCK UCC option, it doesn't want to boot either on Windows or Ubuntu, and the HDD Usage light goes off.
I tried updating BIOS, underclocking some stuff, overclocking but nothing fixes it.
Anyone had this issue and knows how to fix it?

Motherboard: Asrock N68C-S-UCC
CPU: AMD Sempron 140
HDD: Maxtor 250GB IDE
Power Supply: Trust 270W
