Vaio BIOS restrictions?

Search didn't help so I hope you guys can help me.

I've heard that the VAIO Bios is restricted. What does this mean? Can you still disable components you don't need like bluetooth, 56k Modem, Ethernet etc. in order to increase system stability and battery performance?

On my Dell I can choose in the BIOS whether I would like to have non-standard resolutions stretched (and thus blurry) or have them displayed at 1:1 pixel ration with black bars. Is this possible on VAIO notebooks?

Is it possible to boot from USB?

anyone?

 

Unfortunately yes, Vaio BIOS's are more restricted than from most other companies. There are very few options available to you.

You could disable components like Bluetooth, Ethernet, Modem, etc. in the operating system.

I'm pretty sure you can boot from USB. I know one thing missing that is in some other BIOSs is the ability to enable/disable Intel Hardware Virtualization Technology which is on most of the current Intel processors.

It is disabled on all Vaio notebooks. Though with a little hacking, it can be reactivated.

 

What is the the purpose for Intel VT can anyone explain or refer me to a link?
What is the benefits?

 

Thanks rahulnirmal.

I guess I'll have to deactivate the components in the device manager.

 

Virtualization is when you can run another operating system within the current one you are running.

For example, I am running Windows XP right now and can run Linux in a window or fullscreen in XP.

I can do this to run some programs or access features not in Windows XP without quitting XP and then running Linux by dual-booting.

Virtualization can be done in software or hardware, and Intel VT does it in hardware, so generally, the performance will be increased. Intel VT is on most Intel processors, but not in the lower end ones like Celerons.

Intel made it so manufacturers can enable or disable it, which Sony and some others choose to disable it. So when it is disabled, the virtualization process runs in software instead and generally is slower. I like the AMD processors in which their hardware virtualization is always on.

 

Except the new BZ you can turn on or off virtualization on it in the bios and it has intel vPro, can disable alot of the hardware, every port, wireless too just like the g series (though sadly that doesnt have the virtualization option)
