Documentation: *major* cleanup.
Cleanup was long overdue. Old structure was messy and inefficient.

+ <h1 id="t60_ati_intel">ThinkPad T60 (ATI GPU) and ThinkPad T60 (Intel GPU) differences.</h1>
+
+ <p>
+ If your T60 is a 14.1&quot; or 15.1&quot; model with an ATI GPU, it won't work with libreboot by default but
+ you can replace the motherboard with another T60 motherboard that has an Intel GPU, and then libreboot should work.
+ </p>
+
+ <p>
+ As far as I know, 14.1&quot; (Intel GPU) and 15.1&quot; (Intel GPU) T60 motherboards are the same, where
+ 'spacers' are used on the 15.1&quot; T60. In any case, it makes sense to find one that is guaranteed to fit in your chassis.
+ </p>
+
+ <p>
+ There is also a 15.4&quot; T60 with Intel GPU.
+ </p>
+
+ <p>
+ Note: the T60<b>p</b> laptops all have ATI graphics.
+ The T60p laptops cannot be used with libreboot under any circumstances.
+ </p>
+
+ <p>
+ The following T60 motherboard (see area highlighted in white) shows an empty space where the ATI GPU would be (this particular motherboard has an Intel GPU):<br/>
+ <img src="../images/t60_dev/t60_unbrick.jpg" alt="" />
+ </p>
+
+ <p>
+ The reason that the ATI GPU on T60 is unsupported is due to the VBIOS (Video BIOS) which is non-free.
+ The VBIOS for the Intel GPU on X60/T60 has been reverse engineered, and replaced with Free Software and
+ so will work in libreboot.
+ </p>
+
+ <p>
+ The 'Video BIOS' is what initializes graphics.
+ </p>
+
+ <p>
+ See: <a href="https://en.wikipedia.org/wiki/Video_BIOS">https://en.wikipedia.org/wiki/Video_BIOS</a>.<br/>
+ In fact, lack of free VBIOS in general is a big problem in coreboot, and is one reason (among others) why many ports for coreboot are
+ unsuitable for libreboot's purpose.
+ </p>
+
+ <p>
+ Theoretically, the ThinkPad T60 with ATI GPU can work with libreboot and have ROM's compiled for it, however
+ in practise it would not be usable as a laptop because there would be no visual display at all. That being said,
+ such a configuration is acceptable for use in a 'headless' server setup (with serial and/or ssh console as the display).

+
+ <p>
+ There is an Apple laptop called the macbook1,1 from 2006 which uses the same i945 chipset as the ThinkPad X60/T60.
+ A developer ported the <a href="#macbook21">MacBook2,1</a> to coreboot, the ROM images also work on the macbook1,1.
+ </p>
+
+ <p>
+ You can refer to <a href="#macbook21">#macbook21</a> for most of this. Macbook2,1 laptops come with Core 2 Duo processors
+ which support 64-bit operating systems (and 32-bit). The MacBook1,1 uses Core Duo processors (supports 32-bit OS but not 64-bit),
+ and it is believed that this is the only difference.
+ </p>
+
+ <p>
+ It is believed that all models are compatible, listed here:

+ <p>
+ No method is yet known for flashing in GNU/Linux while the Apple firmware is running. You will need to disassemble the machine and flash externally.

+ How to boot an ISO: burn it to a CD (like you would normally) and hold down the Alt/Control key while booting.
+ The bootloader will detect the GNU/Linux CD as 'Windows' (because Apple doesn't think GNU/Linux exists). Install it like you normally would.
+ When you boot up again, hold Alt/Control once more. The installation (on the HDD) will once again be seen as 'Windows'. (it's not actually Windows,
+ but Apple likes to think that Apple and Microsoft are all that exist.)

+ Bus Pirate recommended for external flashing (there are others) and needed tools: clip (eg Pomona 5250), mini usb cable,
+ bus pirate cable (for connecting Pomona to the bus pirate).
+ </p>
+
+ <p>
+ You need to replace OS X with GNU/Linux before flashing libreboot. (OSX won't run at all in libreboot).
+ </p>
+
+ <p>
+ There are some issues with this machine (compared to other computers that libreboot supports):
+ </p>
+
+ <p>
+ This is an apple laptop, so it comes with OS X: it has an Apple keyboard, which means that certain keys you expect are missing:
+ insert, del, home, end, pgup, pgdown. There is also one mouse button only. Battery life is poor compared to X60/T60 (for now).
+ It also has other issues: for example, the Apple logo on the back is a hole, exposing the backlight, which means that it glows. You should cover it up.
+ </p>
+
+ <p>
+ The macbook21 gets extremely hot under GNU/Linux and libreboot; Macfanctld (mac fan control daemon) I'm told is a programme (GPLv3 license) that can help with this.
+ </p>
+
+ <p>
+ Debugging the heating issues (initial work):<br/>
+ Distro: Trisquel 7. kernel(linux-libre): 3.13.0-32<br/>
+ <b>CPU temperatures:</b><br/>
+ 52C(idle)/81C(stress) on factory.bin<br/>
+ 70C(idle)/80C(stress) on coreboot(with microcode updates). libreboot results (without microcode updates) were the same.<br/>
+ (libreboot and coreboot rom's were both built from the same code, just with or without microcode included in the rom)<br/>
+ battery life was higher on original firmware, lower on coreboot/libreboot.<br/>
+ microcode patches included [y/n] makes no difference.<br/>
+ libreboot: 1hr18min left on idle (99% battery), 42mins left on stress (82% battery)<br/>
+ factory.bin: 2 hours left on idle (99% battery), 48mins left on stress (82% battery)
+ </p>
+ <p>
+ Todo: see what the non-free firmware has in it's ACPI tables using acpidump and iasl -d. Try to implement cstate support in coreboot
+ (this will allow for lower temperatures).

+ The MacBook2,1 comes with a webcam, which does not work without proprietary software. Also, webcams are a security risk; cover it up! Or remove it.
