I've tried iPC, and Leo4All on my LG R500
# Intel Core 2 Duo processor T7300 (2.0GHz)
# nVidia Geforce 8600m GS 256MB
# 2GB DDR2 system RAM
# 160GB SATA HDD (5400rpm)
# Wireless LAN: Intel 4965AGN
# 1GB Intel Turbo Memory
And install goes fine, but when Booting into leopard, I can't get past the grey apple loading screen. The wheel is spinning, but it doesn't get beyond that.
