I have followed this link to build my own read out circuit with FT232RL chip.
The dumped EEPROM(ATMEL 24RF08) is here
Expert and the author of 24RF08 has pointed out that the UUID and MAC address are missing (no correct CRC either).
The problem is finally solved by dumping another EEPROM from the motherboard and write the same content into the damaged one.
Doing (and learning on the way) some reverse engineering would be cool. a community effort
This may be made possible by coreboot, some work has been done with X60s.
Dear guys and girls,
I have a Thinkpad X41 Tablet made in 2005. It now cannot pass its self test, stalling at:
....
Video BIOS shadowed
UMB upper Limit segment address: DC00
Mouse initialized
without advancing into boot up stage.
At this point, Num Lock and Caps Lock work, PC Beeper works, and HDD LED sparkles, and pressing Ctrl-Alt-Del can restart the machine. If I press F1 to enter BIOS, or F12 to select a boot media, at the bottom of the screen reads "Entering Setup..." or "Preparing boot up devices..." but no any advances beyond those.
I have met with this exactly the same problem three times. When pressing Ctrl-Alt-Del when a Linux-2.6 kernel is booting, most of the times (N-3 times) the kernel closes spawned threads and happily reboots, but for 3 times the machine stalls at the last step of rebooting (namely after Linux print's "will now reboot...") and after long-pressing power button to power off the machine cannot pass self test like described above.
My laptop is now outdated and not supported by Lenovo. The last two times it broke like this, I turned to a laptop repairing store (after trying more than 5 repairing stores).
It is really a great machine to be around with: I made a lot of (software) customization on this X41 Tablet, and am feeling deep connection with it. It is a "dream" for me to repair it with my own hands (and brain). Please help me.
Thanks in advance.
Yours,
Benda
