Hot dog! I've been getting the exact EFI kernel panics trying to install SL on my ASUS X555LAB. (My old 32 bit Mac can't download any versions newer than SL.) I also tried iBoot legacy, and was able to get the Snow Leopard retail dive to install just like the instructions said! But now, there is a new problem:
When I install 10.6.3 using multibeast (easy beast) I first need to set boot1h bs=4096 because of 4K HDD. That works no problem. But when I try to boot from the Snow Leopard HDD like normal, it only brings up the gray apple logo splash screen and freezes. -v only works for a page or two, and then goes to black screen with no kernel panic. Before it goes blank, I do see "ACPI table not found" flash by. My BIOS is set to ACHI. ????
And THANKS FOR THIS THREAD!
