a.3 Posted September 12, 2012 Share Posted September 12, 2012 Hello there, I'm trying to install Mountain Lion on Lenovo L512 laptop with Arrandale CPU i5-520m @ 2.4GHz (First gen i5 CPUs not Sandy Bridge) and Intel GMA HD Integrated GPU (unfortunately I cannot find the exact GPU model). The other specs if they matter ATM are: Ethernet: Realtek RTL8168D/8111D Family PCI-E GBE NIC and WiFi: Realtek RTL8191SE Wireless LAN 802.11n also I think the MB SB Chipset is HM55. I'm using this method of ML installation The all-in-one guide to Vanilla OS X Mountain Lion + Chameleon + DSDT for beginners. choosing MacBook Pro 6.1 or 6.2 of the premade SMBioses and every time I stuck during boot of ML installation screen either on this row: com_lnx2mac_RealtekRTL81xx: Ehternet address xx:xx:xx:xx:xx:xx I tried different boot switches (-x, GraphicsEnabler=Yes & No, busratio=18, -f, cpus=1) and different combinations of them but I had no luck. Any help or directions will be highly appreciated Link to comment Share on other sites More sharing options...
kermit Posted September 12, 2012 Share Posted September 12, 2012 try: GraphicsEneabler=Yes -f -v cpus=1 npci=0x3000 (or 0x2000). I had this same problem and it worked for me. Now i have ML installed and i try to make ti bootable. 1 Link to comment Share on other sites More sharing options...
a.3 Posted September 15, 2012 Author Share Posted September 15, 2012 (edited) Hi there, Using these switches I crossed the Ethernet line but I stuck several rows later. I will upload a screenshot shortly. Regards. This is what I get now and I cannot tell after which exact row, cause it's too fast: Edited September 15, 2012 by a.3 Link to comment Share on other sites More sharing options...
a.3 Posted September 19, 2012 Author Share Posted September 19, 2012 When I try to boot with these switches: GraphicsEnabler=Yes -f -v cpus=1 npci=0x3000 busratio=18 I reach this line and then it hangs: Link to comment Share on other sites More sharing options...

a.3 Posted September 20, 2012 Author Share Posted September 20, 2012 I've done what you suggest, but also no luck This is my devices list gathered from windwos system info. Now I tried this guide http://www.insanelym...howtopic=281192, but I end with the same results. Maybe I mistake something in general. Link to comment Share on other sites More sharing options...

a.3 Posted October 3, 2012 Author Share Posted October 3, 2012 Thank you I finally install Ml, but the graphics 8086:0046 work only in resolution 1024x768 with no QE and I cannot change it to native at least. Any ideas and how to move this topic to post-install? Link to comment Share on other sites More sharing options...
