"Legacy USB Support" in UniBeast 1.5 for ML: which motherboards need it?

[darukaru]

The description for this option in UniBeast says "Choose this option to rollback USB for LGA 1156 motherboards that don't enable Rate Matching Hub in BIOS." Is there a list of motherboards that need this option to be checked? Are all Gigabyte boards affected?

Does anything particularly bad happen if you don't check it and try to boot from the install stick anyway?

Or should I just be waiting for the full installation guide to be posted?

I have a relatively old mobo.. I did not check that option.. It did not hamper my install in any way..

worked fine for me..

Not really. The only thing that might happen is that you cannot reach the installation assistant. If so, redo your UniBeast USB installer and select that option. Depending on your motherboard, you may need to apply this fix, even with 1155 LGA sockets.
