Jshatch:

Quoted from the article:

"Memory Stick and xD Picture Card reader

Not used in Thinkpads (controller functionality disabled). "

That doesn't make sense. Why would Lenovo specifically market it as a 4-in-1 reader if they intentionally disable 2 of the 4?

Jshatch: TPM removal???

Q: Good or Bad?

Someone said: This Security Chip is a hardware trojan. True or false?

== hmmm. depends. but the fear is big, that it is trojan... ==

Hello,

I would say it depends, how TCPA/'Fritz'-Chip is used. But the fear of the critics and (cyber) civil rights people are, that the industry wants to control the use of digital media like MP3, DVD, etc. to prevent copying - even if you own it.

There is also a fear, that there are hidden channels in this black box type of hardware, because hidden channels where found in so many black box type of hardware for years now. What is transmitted over these hidden channels?

The recent modifications by the TCG because of the critic and the resulting pressure are a good beginning. We, the consumers and users, have to go an with our demands, with our critic and we have to look carefully, what TCG and the others are doing here.

Why? Because it will affect all of us sooner or later in using our MP3- or DVD-Players or e.g. -Software on our computers etc. And you can think also about your mobile cellular phones, digital cameras and so on. Digital content, digital media is more and more widespread.

And this is where Digital Rights Management (DRM) comes into the game. DRM is feared to be a trade barrier for a free market, a barrier to future historians, etc.

Trusted Computing is not bad by meaning, but it is bad (or 'lousy'?), how the industry is implementing it. They could do better, right?

== ESS page may have errors... ==

Hi, The ESS 1.0 section claims that its based on TCG 1.1 specs, but I cannot find anything to support that. The ESS 2.0 systems I have all have v1.1 TPMs in them, but I don't have an ESS 1.0 system. As far as I know, the ESS 1.0 does not implement any TCG specification.

Also, the ESS 2.0 does not provide a TCG 1.2 TPM. No currently shipping IBM platforms contain 1.2 TPMs. I thought I'd mention this stuff somewhere before just changing the wiki with no discussion.

Thanks

Thanks. You could have just changed it and leave a note with pointers to your sources. I also wondered about the fact that IBM says nothing about TCG in ESS 1.0, but i didn't find any more detailed information. Did you? And if so, where?

[[User:Wyrfel|Wyrfel]] 19:59, 12 Jul 2005 (CEST)

Yeah, I am seeing less and less on ESS 1.0 on www.ibm.com, which is my source for this stuff. If I come across anything concrete, I'll post it.

== X60, X60s and T60 with TCG 1.2-compliant Atmel chip ==

Lenovo's "Personal Systems Reference" on Thinkpad Notebooks version 301, January 2006 states that Thinkpads X60, X60 and T60 are equipped with a "Trusted Platform Module / Atmel chip / TCG 1.2-compliant".

Could this be the Atmel AT97SC3203?
Can anyone confirm this?

What about linux support for this chip?

Update: In the same document I found "LPC bus (PC87382 Super I/O, AtmelÂ® 97SC3203)" in the architecture section.
----
I believe that TCG 1.2 includes an API for software communication with the chips, so the drivers should be chip independent. Not sure, though.

== TPM removal??? ==

So, according to the photo in the article, the TPM chip is on a removable daughter card. With the chip removed, will the PC still operate as a normal (non TPM-enabled) PC?

IBM Integrated Bluetooth IV with 56K Modem (BMDC-3)

=== IBM Integrated Bluetooth IV with 56K Modem (BMDC-3) ===
This is a combination USB Bluetooth and AC97 Modem Adapter that is installed in a [[CDC slot]].

* USB VID/PID: 0A5C:201E
=== Modem Features ===
* Chipset: Conexant

=== IBM Partnumbers ===
*IBM FRU PN: 39T0022 ($37.50 in July 2005) - ''no longer available at IBM''
*IBM FRU PN: 39T0024 ($49.00 in September 2005) - ''no longer available at IBM''
*IBM FRU PN: 39T0026 ($50.00 in January 2006) - ''shows "call" under availability''

This part takes the place of the 56K Modem board.
It requires a Bluetooth antenna, and some ThinkPads built without Bluetooth already have the antenna installed -- the antenna wire may be found disconnected and taped under the Modem board. To ascertain if your unit has the antenna you can check the parts list, or remove the keyboard and verify that there are 3 wires coming out of the left of the LCD towards the CDC, as in [[:Image:T43-2686-DGU-CDC.jpg|this picture]] (two WiFi antennas and one Blueooth antenna) or [http://www.pbase.com/kenn/t42_bluetooth here].

In addition to the Modem/BT module, a Bluetooth Thinkpad also uses an extra indicator LED below the LCD display, and another indicator LED on the top of the lid. To see these two LEDs, two new clear plates are required. The entire set of replacement sticker plates can be ordered as FRU 26R8409 ($14.00 as of January 2006). (formerly FRU: 13R2455)

As of January 2006, IBM charged $13.50 for Airborne shipping, for a total of $77.50 (in US + tax) for the BMDC-3 and replacement sticker plates.

=== Linux Bluetooth driver ===
The Bluetooth device is implemented using USB. Enabling/disabling bluetooth (i.e. by use of {{key|Fn}}{{key|F5}}) leads to USB connect and disconnect events.

As Bluetooth is implemented using USB, this will only work with USB drivers enabled:
:{{cmdroot|modprobe uhci-hcd ; modprobe ehci-hcd}}

The <tt>bcm203x</tt> kernel module, which is included in recent kernels, supports this chipset. You have to make sure to '''compile it as a module''' since the kernel won't detect the chip at boottime (when Bluetooth is turned off).

Use BlueZ-utils (http://www.bluez.org/) or fancier software like the GNOME Bluetooth subsystem (http://usefulinc.com/software/gnome-bluetooth) to use the device.

Some problems have been reported using bluetooth after a suspend/resume cycle on the T43. These problems can be mitigated by unloading the USB kernel modules (uhci_hcd, ehci_hcd, hci_usb, bcm203x) before the machine is put to sleep, and by re-loading these modules when the machine wakes up again.

On a T43p you must ensure that you call hotplug (re)start upon resume or you will lose bluetooth functionality. See the ACPI area for sample suspend scripts, or if bluetooth flakes on a debian system at any time you can manually call
:{{cmdroot|/etc/init.d/hotplug restart}}
and it will come back with another {{key|Fn}}{{key|F5}} press.
