Hallo, Would you help me on a coreboot port? I just installed coreboot on a Thinkpad X60 following the wiki. Now I want it on this mid-2007 macbook2,1 too. I read some pages in the wiki and started to collect information about the macbook. it seems it has no superIO chip and I dont know what to think of the ectool output. As I understood by now, not knowing how the ec might interfere with the bios or coreboot is one of the big obstacles, no? I hope that once I would try a coreboot flash, recovery might be possible by an external programmer (which I do not have, yet). the flash chip is the same as on the X60 (I've read the factory bios already) as is the northbridge and southbridge. an usb debug port seems available. I've put the log files here: http://macbook.donderklumpen.de/coreboot/ Any comment about what you think about this and how I should proceed is very much welcome!
Good news is that other than EC and some minor points, your macbook is a copy of X60. With some luck a qualified dev can do it in a week (you may want to post bounty for it). You need to get console. EHCI debug would be the best option on your laptop. http://www.coreboot.org/EHCI_Debug_Port#Finding_the_USB_debug_port Take USB 2.0 stick and plug it into different port until it appears as device one on bus 3.
I meant port 1 on bus managed by ehci_pci (exact bus numbers are unstable)
You'll have to make a USB debug dongle or buy one (short supply). You'll also need to find your flash chip. Your laptop has this chip: http://orzparts.com/index.php?main_page=product_info&products_id=732 You'll have to teardown the whole laptop, looking at every chip which seems similar. Remember to discharge from static electricity before opening your laptop and not to wear anything that produces it. This has a risk of breaking your laptop, proceed at your own risk, you've been warned.
thanks Mono
