Request to unlock advance features in Acer Aspire 5740 Bios Phoenix 1.28
#61
Thanks Frok1966!
So, just to be sure: I've got an acer 5740g with an i3 processor m330 2.13GHz. Is it OK to upgrade this rig  to the CPU 20655 and the I7-640M ? I've found it online used at interesting (low) prices.

Should I upgrade the cooling hardware too?

As for the SAta caddy not being recognized: I've read elsewhere that it's a bios version problem, and in the latest version, at least 1.28+ the  problem has been fixed.

Meanwhile I've mounted my SSD HD as the main one in the first sata connector, so I kept my DVD recorder in and everything boots fine.

again, thank you very much in advance!!! Smile

I landed in this forum to solve a problem with bios hanging at boot eachtime I connect a sata caddy in the dvd sata slot, with a sata disk.
The disk was recognized by the bios but it hang up at boot.

Can I upgrade the cpu buying a used i7-640m online, and the use the bios Eugen88 provided?
It would also avoid spectre and meltdown vulnerabilities?
Would it show me locked bios menu screens too?

thank you very much in advance.

Hello, 
My suggestion is: flash again the bios with the official one and start to understand which components could be the cause of bios hanging each time.
Once you have found the issue, replace the component. have you tried to replace the RAM? or the small battery? remove the WIFI and Bluetooth card.
Once you have fixed the issue then you can start to upgrade with the new BIOS and if you wish with a powerful CPU.

The Updated BIOS (with the latest microcode) does not unlock the bios. 

Hope this answer to your doubt

Hello
Again, first of all, try to update with the latest bios 1.28 of the 5740G.
See if the issue disappear. if not, you have to investigate more before try the mod bios.

I have the bios vers. 1.28 and I don't have any problem with the sata caddy.
I have also the cpu i7-640m with no upgrade of cooling system as the two CPUs have the same TDP.

The bios modified is simply the bios 1.28 where it has been updated the microcode relative to the cpu 20655.

hope this clarify

Many thanks for your help.

Could you do us a big favor by applying your mod onto Sml6397's unlocked bios on page1 of this thread? 

many thanks!

Hello

I have compared the Original bios and the one hacked at page 1.
I have found 16785 differences, so I don't understand which the modifications are.
It is difficult to modify the job of the others, maybe you should ask to the author of the mod to update the bios as per your requirement.
