Trying to install ML on Lenovo L512 (Arrandale i5)

[a.3]

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

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.

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:

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:

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.

hello

 

try also remove appleintelhd*.kext

 

i think u graphics is 8086:0046 many problems in mac os x

 

make the installer simple, without any extra kext, the extra kext are post install

 

to configure the system

 

u signature , i think u are installing in that config

 

good hack

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?
