how to install Genode on PC machine

[Ivan Loskutov]

Hi Jian,
1) I've used iPXE because it has good code and I can change this for my
needs. Grub seems more difficult for modifications for me. Second cause -
network boot is better for debuging. You can modify Grub or your other
prefered bootloader.
2) For my case I was need to configure RAM for fit l4linux to memory of my
PC. I don't think that NIC driver error is caused memory layout.
