之前我的Z117升Windows10因為顯卡不合，無法升級我也就作罷了
前幾天因為工作需要，發現Unity開起來會crash, 原廠回我是因為顯卡要更新
於是拜訪了google大神，到底怎樣可以更新Z117的顯卡驅動程式
皇天不負苦心人，終於被我挖到文章，主要是在教人如何升級到Windows10，而更新顯卡驅動程式是其中一個步驟
原文在此，可自行參閱
http://forum.notebookreview.com/threads/sony-vaio-vpcz1-upgrade-and-clean-install-to-window-10-with-bios-hack.797999/
其他步驟我都沒試，所以有興趣的人請自行參閱
我只有將顯示卡GT330M的驅動程式更新成目前NVIDIA的最新版本
(強烈建議要試的人請先自行備份，電腦如果因此出問題請勿找我，我只是分享我成功的方法，但我不保證每個人都可以順利完成，
安裝完後目前我用了一個禮拜，一切正常，唯一的副作用是無法動態切換SPPED跟STAMINA模式，切了以後要重開機才能作用，除此以外，外接HDMI是正常的，快速鍵等等都沒問題，如果可以接受再繼續往下看)
我做的步驟如下
1. Use the RUFUS tool above to create a new bootable USB, MS-DOS mode
用任何一個工具製作一個可開機且帶有FreeDos的隨身碟
2. Download a tool call FLASH*T (* = I, remember to replace * = I from now on) 請參考附檔
附加壓縮檔: 201706/mobile01-bf6d5b3c735e92113e2aa6bc571db374.zip
3. Download a tool call PYTHON here http://portablepython.com/wiki/Download/, just use 2.7.x.x, don't use 3.x.x.x，檔案太大請自行下載
4. Install PYTHON onto your bootable MS-DOS USB
將PYTHON安裝到第一步驟做好的隨身碟根目錄中
5. Download advance menu for your hack bios here http://forum.notebookreview.com/attachments/advanced_menu-zip.48026/
請參考附檔
附加壓縮檔: 201706/mobile01-8c266bb765cfbed98169b46d589a14f6.zip
6. Extract the zip, you get the file ADVANCED_MENU.PY
解壓縮第5步驟的zip得到ADVANCED_MENU.PY
7. Copy ADVANCED_MENU.PY into APP folder in the PYTHON folder
Copy ADVANCED_MENU.PY到隨身碟中PYTHON目錄裡的APP目錄下
8. Use USB to boot into DOS, after booting, at C drive (or any drive), then type dos command:FLASH*T DUMP.ROM /G [Enter] (copy you your original Bios into USB)
先重開機按F2進到bios中，設定成外部usb開機優先，接著用剛剛做好的隨身碟開機進到DOS
下command: FLASHIT DUMP.ROM /G 然後按[Enter]
9. remove USB, boot into Window and plugin USB again
移除usb重開機後進到windows再插入usb
10. Copy DUMP.ROM into APP folder in PYTHON folder
Copy剛剛隨身碟根目錄的DUMP.ROM到隨身碟中PYTHON目錄下的APP目錄下
11. run CMD from window to open command prompt
在windows下叫起CMD
12. Change (CD) to USB drive, then goto (CD) APP folder in PYTHON folder, then type dos command:PYTHON ADVANCED_MENU.PY DUMP.ROM NEW.ROM [Enter] (Tweak your bios into NEW.ROM file)
切換到隨身碟的那一個槽，然後進到PYTHON的目錄下，之後下command: PYTHON ADVANCED_MENU.PY DUMP.ROM NEW.ROM 按[Enter]
13. Quit the command prompt and copy NEW.ROM back to root directory of USB drive
離開cmd，用檔案總管將剛剛產生的NEW.ROM copy到隨身碟的根目錄下
14. Reboot using USB drive, after reboot, at command prompt, type: FLASH*T NEW.ROM /F (flash your tweak bios)
再次重開機插著隨身碟進到dos，下command: FLASHIT NEW.ROM /F 按[Enter]
15. After finish flashing, reboot，during reboot, quickly press F2 to enter Bios setup
之後再重開機，重開機時按F2進到bios設定
16. In Bios setup, find the VGA mode (advance menu) and change it to STATIC, you need to do this otherwise window will hang at black screen when install nVidia driver later.
找到advance menu, 然後將VGA的選項改成static，原先是auto
17. reboot後進到windows
18. 從NVIDIA 網站下載並且Install 需要的NVIDIA graphic driver, 會安裝失敗，留下C:\NVDIA資料夾
我是下載這個
http://www.nvidia.com.tw/download/driverResults.aspx/112694/tw
19. Run VAIO_Z1_330M_INF_Patcher.exe from VAIO_Z1_330M_INF_Patcher.exe.v4.8
參考附檔，下載zip解壓縮後，執行裡面的VAIO_Z1_330M_INF_Patcher.exe
附加壓縮檔: 201706/mobile01-de2f586e26cf5341ea145ea3456bb0f6.zip
20. Patch the driver in C:\NVIDIA with either VGA or 3D Vision option, whichever you prefer
選擇VGA PATCH
21. Enable TEST MODE in ComputerCowboy patch, switch graphic button to SPEED mode (nVidia mode)
確定顯卡切成SPEED模式，選擇Enable TEST MODE，接著電腦會重開
22. Run VAIO_Z1_330M_INF_Patcher.exe then select "Launch nVdia Installer"
重開再度進到windows後，執行VAIO_Z1_330M_INF_Patcher.exe，選擇Launch nVdia Installer
此時就可以正常安裝完成
23. 安裝完後，選擇Disable TEST MODE重開後就完成整個更新GT330M驅動程式的步驟
