Thank you so much! But I'd like to downgrade to 2.09 version. I think this is the only way to bring back the sata3.
PS: sorry, my english is not so good.

thank you again.

I had a problem with the recovery mode: a Sandisk Cruzer Titanium was not recognized.
When another was used it ran Bios 2.09.
As the machine already has another Wi-fi AC card with Bluetooth, it continues to work and the SATA indicates 6Gb/s.

Thanks to the whole community for the support!

Well, I managed to brick the machine. I set the video ram to 384mb and the machine will no longer boot, nor can I access the recovery mode to flash back to the stock bios: while I can use fn+esc to get it into recovery mode (seemingly), it never reads the usb drive with the bios on it. I tried shorting the CMOS reset jumper, but still no luck. How a simple setting change in the BIOS can brick a machine so badly a CMOS clear won't fix it, I have no clue. Looks like I'm well and truly screwed.

Any help you could provide would be deeply appreciated.

Hello, sorry to bump up this thread, but I suffer the same problem, also same setting vram too high (I set it to 1024MB)

Now this rare spec laptop definitely unusable, I cant even load bios file thru Fn+Esc key, looks like the core bios was protected by SecureBoot that turned on by default

I do wish there's any workaround to fix this :( unfortunately there's none replacement board that have i5 3337U in here like what I have now
