how to backup bios for Sony Vaio FW-4ZTJH?

Hi nobus, thanks for the backup. The backup is just for being safe after the bios update that I need to see the virtualization section that Sony removed deliberately.

My system is fully operating, no problem but only for virtualization, that most of virtualization programs need for it and since the bios is reduced and VT is not visible in bios, I need to have it desperately.

Update: I tried to appy the Mr. Levicki's solution to my Vaio. I formed a USB that is formatted as Fat-32 and put the files as he states in the readme.txt but after the boot, simply, it didn't boot with that USB. The system passed directly to my grub screen.

When I boot a non-Vaio machine, the booting operation stucks and I think this proves that the USB is working fully but my Vaio cannot recognize it simply. It's a standard 1 G kingston, no U3 property.

Note that, in the readme file, Mr. Levicki says "put the bios default and you can change the boot order." So, I put the bios to defaults. Naturally, bios sets the boot order from hard drive and disables the external boot which USB case, and I set it enabled and change the boot order as external but as I said, it passes without any glitch to grub screen to choose OS.

So, do you think the patch doesn't suit me or do i miss stg according to the instructions?

Best regards...

are you sure the vaio can boot from usb?  many cannot, or have a very limited ability to do so.
i have one that will boot from an usb ubcd stick, but not from sticks that i try to boot to dos from...

also, i'm not sure what you mean with "I need to see the virtualization section that Sony removed deliberately.
"

let me try to boot with DVD? But there is a selection for boot order as external device? Why on earth Sony put it then?

that you shuld ask them, it may be intended for an usb dvd, or so

ok...

>>As far as installing it -- when you formatted the USB stick did you make it bootable?    Have you >>confirmed that on another system

I have formatted USB as FAT32 and simply copy paste the files and set the boot order from bios as external devices first. Of course, prior to this, I change the BIOS to system defaults as Levicki's said in readme.txt

But, while I was booting the machine, it simply passed to harddisk and I was thinking the USB is not bootable and put it to another machine that is not a VAIO. When I booted with that USB, it locks as blackscreen and cannot get into to the OS. So, I guess the USB is 100% but incompatible with non-Vaio machine. (Though I am not sure, I mean to make it bootable, the bios setting is enough or maybe I need something as syslinux to make bootable?)

I will try it for USB floppy drive or do you suggest to do the operation with a CD which is scary if that stucks.

Best regards...


CrystalCPUID or VTCtrl

>>CrystalCPUID or VTCtrl
and I haven't seen that information in the readme or anywhere else. If I successfully patch the bios, what is the risk of configuring those programs. I mean is there risk of those programs to brick my machine after the successful bios patch?

>>Just formatting the USB stick with FAT32 does NOT make it bootable :-)     You need to add an >>operating system ... MSDOS, for example

Ok, but should i simply install MSDOS to that USB? or what? any guide regarding this?

>>SOME  models

I am not sure, mine will be in the list. You have any knowledge regarding this?

thank you:)

I'd like to wait for a while for an update but if it doesn't appear in 3 months time, I will be patching.

update: Sony announces a bios update for some models, luckily mine is also in the list, I downloaded the update and install it...Voila!
