Hi all,

I'm not sure if this is really the right place for this, but here we go...

I've got a 64-bit laptop (Acer Aspire 5810T) with a crippled UEFI BIOS, which doesn't have an option to enable VT. This is a major pain, but my googling suggests this is quite common on laptops. As my UEFI BIOS won't boot from UEFI partitions(!), I can't try this hack http://feature-enable.blogspot.com/2009 ... -vaio.html to sort it out.

I can think of 3 work-arounds to this, and before I embark on a steep learning curve, I'm looking for any definite reasons why they would never work:

#1 - Enable VT-x outside the BIOS, e.g. in a bootloader such as grub/grub2. I have a nasty suspicion that I'll find the necessary register/flag is locked before the bootloader ever sees it.

#2 - Patch VirtualBox to work without VT-x

#3 - Patch a BIOS image, and re-flash. The big danger here is bricking my laptop...

So, before I embark on a world of pain, does anyone have any comments?

Thanks,

Phil

1) If the BIOS disables VT-x and locks the method to enable it, then nobody can change it until the system is rebooted
2) VirtualBox works without VT-x.
3) Quite dangerous

Had anyone got lucky enough to enable VT option in 5810T?

Except the ones made by sandervl, I have one : don't. (for #3)
