I have Plan 9 booting on an Intel Macbook. When I was
first testing it out, there were problems with the
SATA driver but Erik fixed those and it works fine
now. The only change that you'll have to make is in
the keyboard initialization for both the kernel and
9load.

Add the following at the beginning of these functions:
	/sys/src/9/pc/kbd.c:/^kbdinit
	/sys/src/boot/pc/kbd.c:/^i8042init

+        c = inb(Status);
+        if(c & Rtimeout){
+                print("no keyboard present\n");
+                return;
+        }

Oh, and you're going to need to supply a plan9.ini
with sufficient parameters since you don't have
keyboard input until you can run usb/kb.

If I get some time on Saturday, I'll post a write-
up on how to bootstrap the system using a spare
partition on the Mac.

Also, I started an ethernet driver for the Yukon 2
chip that's in the Macbook. I had to put it aside
for a while but I'm slowly getting back into it.
