Is it possible to create HVM guests on Sony VAIO FE48G ? I am getting the "HVM guest support unavailable.." error. I believe the processor is not the problem as Intel T7200 seems to have VT-x capabilities (?) The problem seems to be with the BIOS. Did someone see a BIOS update or a utility similar to VT-enable to do the magic ? Or I am missing something very basic ? thanks - Amol
On my Dell laptop I had to enable VT-x extensions in the BIOS before I could boot Windows in HVM mode. By default the vtx extensions are disabled on most platforms !!! -surya Amol Chiplunkar wrote:> Is it possible to create HVM guests on Sony VAIO FE48G ? > I am getting the "HVM guest support unavailable.." error. > I ieve the processor is not the problem as Intel T7200 seems to > have VT-x capabilities (?)

If you don''t see an option in your BIOS to enable HVM support, you''re out of luck. There should (*) be no way to reenable it once the BIOS turns it off. I have a Vaio with an HVM-capable CPU, but Sony''s decision to disable it in the BIOS means that a) my current Vaio is an expensive paperweight, and b) my current Vaio is my last Vaio. Nils (*) I say ''should'' because there were reports of Parallels being able to enable it on the Mac before Apple enabled in their BIOS. Maybe Parallels modified the Apple BIOS? I don''t know, but I''d love to hear a definitive answer.

Apple does not use BIOS, it''s more modular, think GRUB or some type of advanced booter, but in hardware with software assistance. When they added "Boot Camp" it was really an EFI module and update to HFS+ and their diskutil tool, all interfaced through the assistant. The hypervisor is disabled for a reason by default on economy Macs, it''s to do with virtualization causing heat most likely, and probably quality concerns as well. Parallels wasn''t the one to enable it, they tell users the Apple method to do so. BIOS is hard coded off the factory line, only flashes can fix the problem and add functionality, and even then a lot is still unchangeable. VMware''s Fusion product also uses the VT extensions on Macs, and they too cannot unset the toggle, due to AppleCare Protection and Mfc Warrenty claims. James

With EFI software modules can execute at the equivalent of "BIOS" time.

I have a Vaio FZ11Z and successfully change the NVRAM of Phoenix Bios to Enable VT on both cores, FZ11Z uses Bios R0050J7, so I guess your vaio use a diferent bios, address to change from 0000 to 0001 will be different, but process will be the same can give you more details or point you to some "bios hack'' forums if you are interest in that kind of approach.

The problem is that Sony''s BIOS doesn''t enable VMX, and locks MSR 0x3A so that it can''t be enabled by the operating system later. The general idea is to try to find the NVRAM symbol that sets VMX and write it back into NVRAM. To find right location you have 2 methods. First (an example follows), you can disassemble your BIOS ROM image (I use ndiasm): 0000A866 66B93A000000 mov ecx,0x3a ; MSR VMX control 0000A86C 0F32 rdmsr 0000A86E 660FBAE000 bt eax,0x0 0000A873 7218 jc 0xa88d 0000A875 50 push ax 0000A876 B89501 mov ax,0x0195 0000A879 9A204100F0 call 0xf000:0x4120 0000A87E 58 pop ax 0000A87F 7405 jz 0xa886 ; ZF set == VMX disabled 0000A881 660FBAE802 bts eax,0x2 ; Enable VMX 0000A886 660FBAE800 bts eax,0x0 ; Lock MSR until power cycle>From this example you will need to check the call to 0x4120If you find that way too hard and have some patience, keep on using trial and error. This is the best way I can think of to explain this to you, by just posting what I did on my own Vaio. 1. On my Vaio I only have Nevada and Fedora, so I boot from a USB floppy, with a disk created with FreeDOS ( http://www.esupport.com/techsupport/UTILS/bootdisk.exe ), you will also need symcmos tool from Phoenix ( ftp://ftp.supermicro.com/utility/symcmos.exe ), and an editor. I use a DOS version of VIM, but any text editor will do. you can ofcourse use any other available boot method, you just need that "symcmos.exe" works. One way I didn''t test was if it would work on WINE. I strongly sugest you to disable all BIOS passwords (if set), so that if something goes wrong it''s easier to recover. 2. After booting with the FreeDOS disk, dump your NVRAM symbol table using: symcmos -v2 -lNVRAM0.TXT NVRAM0.TXT will look something like this: ( SYMBOLIC CMOS EDITOR - Version 643710-032 ) CRC = 0842 (0000) [0001] (0003) [0000] (0006) [0001] (0009) [0001] (000C) [0000] (000F) [0001] (0012) [0000] ..... ..... ..... (069F) [0000] (06A5) [0000] (06A8) [0000] (06AB) [0000] (06AE) [0000] Symbol table from FZ11Z BIOS R0050J7 will range from 0000 to 06AE. Im my situation, at this point, I already suspect from 02D3. If you use trial and error keep in mind the following: NEVER change a symbol diferent from 0000, and only set those to 0001! You can use a binary search approach here, but with some hints to reduce your path. I found out from playing with other ROMs that VMX symbol is usually at 02xx range or at 03xx, other ranges seems rare. I sugest 02xx, 03xx, 04xx and 01xx (by that order). Start by changing all 0000 to 0001 from 02xx range, verify, if successful just use binary search on correct range to find and set the ONLY correct symbol in final version. I also noticed that many times the VMX symbol is one or two symbols bellow another one with value 5. Seems it''s something related to the dispacher function call, but I am not a BIOS hacke r so i am not sure if that is correct. on FZ11Z that applies: (02CA) [0000] (02CD) [0005] (02D3) [0000] ---> 0001 (magic symbol on FZ11Z, with BIOS R0050J7) (02D6) [0001] 2a. Save file with changed symbols, eg: all in range 02xx (ONLY 0000 to 0001), with another file name (allways keep original dump). eg: TRY01.TXT 2b. Update BIOS NVRAM with new table: symcmos -v2 -uTRY01.TXT Now reboot and check if VT is enabled. You have several ways of doing that, I find using the VMware iso for that purpose the faster one. Get it at http://ftpsite.vmware.com/download/vt.iso Now if VT is reported enabled you won! You just need to use binary search on "lucky" range to get just the magic symbol for a last NVRAM update, (try to use some hints first). If not enabled yet, use original dump again and create another file with a different range with ONLY 0000 changed to 0001. I think at this time you may have some questions, and I will try answer the obvious ones now... Q. Can I block my Vaio? A. To be honest I think that will be very very hard to happen, but possible. You can always boot with FreeDOS disk and update with original dump, or reset. Worst scenario will be having to reset your BIOS by opening your Vaio. Q. If I break it, will you pay it? A. No! Do it at your own risk! Q. Will the change be permanent? A. No, you will loose changes in 2 situations (at least that I am aware of): If you reset your BIOS options or if you upgrade it. Q. Is this the ideal solution? A. No, Sony really needs to start listening to their customers. Q, Is this the ideal hack? A. No, a better one would be to find a way to activate the dispacher menu (the one that allows you to set VT on/off) from phoenix BIOS menu, and patch a BIOS image with that (I am working on that one now). Q, Are you the one to credit for all this? A. No way! Im far from being a truly BIOS hacker, kudos on this will be entirelly to the guys that did the first findings. I just compiled some information and applied it on my Vaio FZ11Z with sucess. Good luck, and please report back your findings and success, or misfortunes! :| Kind Regards, CA, This message posted from opensolaris.org

Thank you very, very much! It took a long time (trial and error) but i did it!!! Sony Vaio AR21S : (0195) [0001] one important note: i had to power off an on again! simple reboot with ctrl-alt-del did not enable VT This message posted from opensolaris.org
It would be useful to link to the original forum thread (where your examples were first published) where the hacking of the Intel CPU/Phoenix BIOS VT functionality is being reported, and where those who are becoming expert in the techniques can advise on the potential dangers. http://www.wimsbios.com/phpBB2/topic9326.html This message posted from opensolaris.org

Just a little contribution to this topic (although I know the thread''s very old and probably inactive): Bios image file R2101Q0.ROM VT enable register found at 0x5BB. Change the value from [0000] to [0001] to switch it on Hope this helps. Best of Luck to all of you. This message posted from opensolaris.org

Hello. I saw that it is old. But it can''t be too much helpful information, right? :) I just did this thing with my notebook and now happy. Thanks for instructions! May be it will help to someone that notebook is Sony Vaio VGN-FZ11MR (for google: fz, fz11), it has Phoenix BIOS version R0050J7 and it is needed to set register 02D3 from 0 to 1. (Also big list can be found there: http://www.allquests.com/question/678250/How-to-Enable-Intel-VT-and-AHCI-on-a-VAIO-SZ.html ) So happy :) Thanks :) -- This message posted from opensolaris.org
