How do you enable EFI boot ??

Hi people,

I have a SONY VAIO VPCEB2M1E/WI laptop with AMI Aptio EFI firmware, but I cannot find any option to enable EFI booting.

Is it possible to hack the AMI Aptio firmware somehow to enable EFI booting??

Why is SONY so stupid to disable the EFI booting feature?

Again, why are they so stupid?

For a third time, WHY ARE THEY SO STUPID?!?!

 

dont take it for granted that you are smarter than these companies.

 

1.) They aren't "stupid"
2.) Describe what type of EFI boot you are looking for and why.

EFI boot used to be enabled in early Sony EFI models (about 2 years ago). 2 problems.

1.) It caused Win 7 to randomly blue screen
2.) It opened up a pretty big security hole (which was exploited)

EFI boot was disabled in subsequent BIOS releases.

 

All the new S series models use insyde h2O uefi boot. The insyde h2O (bios) seems to be the preferred way amongst a lot of manufacturers now. You wont be able to enable or disable uefi boot. Its either there or no.

 

Care to elaborate? You have confirmed you can EFI boot on a new S? Would be news to me.

EFI BIOS (ie the insyde h20) doesn't mean you get efi boot. Case in point is VGN-Z - insdye h20 efi bios. We had efi boot. We exploited it. We then lost efi boot. Also lost efi boot on VPC-Z. I'd be quite surprised if it showed back up on the new SA.

 

I need EFI boot to avoid rootkits that store their code in the MBR.

And also to stop people trying to install "windows loaders" that also put their executable code in the MBR.

Hewlett-Packard allows me to enable EFI booting in many of its laptops. Why doesn't SONY do the same!?

 

^I already answered your question. Let's not pretend that EFI boot doesn't have it's own security issues.

 

Yeah, I guess that malware writers will probably target EFI in the future, but currently they are not.

They only target the MBR, so in the meantime I would be protected by switching to EFI booting.

What are the security issues that SONY found?

 

^The fact that we booted via efi on a usb flash disk and with just a couple keystrokes changed some pesky bios code. Without even flashing.

 

Ahm, well, typical of SONY. They are much more concerned about their own security (to protect the secrets of their hardware) than the security of their clients.

They do the same with the PS3. They put a lot of effort in hiding and protecting the secrets of the hardware, but they don't seem to care much for protecting and securing the customers privacy and credit card details...

That's another reason to call them stupid!

 

^Not sure I agree. Disabling something that could cause an infected flash drive to torch the bios (and thus your laptop) seems to be reasonable to me.

 

But wouldn't it be more reasonable to fix the problem instead of disabling the feature?

 

They did fix the problem, they disabled the efi boot

 

Yep, and it's stupid. That's why I called them stupid.

Somehow, Hewlett-Packard, Dell, and many other manufacturers can enable EFI booting without having those problems.

Perhaps SONY should learn something from those other manufacturers to be a little less stupid?
