deboopi posted a topic in NotebooksMachine specs Sony VPCSB1X9E specs processor: Intel Core i5 2410M Clockfrequency: 2.3GHZ Chipset: Intel HM65 RAM: 8Gb Memory type: DDR3 Mem clockfreq.: 1333 Mhz GPU: AMD Radeon™ HD 6470M + Intel® HD Graphics Network: Realtek PCIe GBE WLAN : Intel WiFi Link 1000BGN Extra Installed a 256GB an CZ Vertex4 in the dvd bay Changed bios : boot from external boot from dvd boot from hd I already had a look at these links http://www.tonymacx8...series-svs.html http://www.insanelym...o-sasb-vpcsasb/ But one talks about Lion and the other one needs setups done from a Mac and bios modification. I was able to set it up on the second partition from the SSD (primary partition) while booting from usb installation mentioned hereafter Installed from File OS X 10.8.2 Install USB.rar from the piratebay The Readme of this usb install reads If you need, use TransMac to delete kexts which are causing problems (System/Library/Extensions) and delete kernelcache (System/Library/Caches/com.apple.kext.caches/Startup) http://www.asy.com/scrtm.htm If boot stops right before reaching the installer, or graphics aren't working right, delete video kexts: ATI = ATI* Intel = AppleIntelHD* and AppleIntelSNB* nVidia = GeForce* and NVDA* When deleting those kexts and kernelcache I can install ML on my vaio, I can boot but no mouse. This is because I'm using a Logitech Anywhere MX wireless mouse which needs to be installed afterwards. When plugging a wired serial mouse in the first USB port sometimes I can use the mouse But I have no wifi, I know the problem with the intel link 100 so i already ordered an Atheros AR9287. But I'd like to have a ootloader installed and so on, so I'm still looking for someone who has already installed Mouutain Lion on the same machine or something that's very close to it.
