If you haven’t bought an T500 yet: the Dell Latitude E6400 is much easier to flash; no disassembly required, it can be flashed entirely in software from Dell BIOS to Canoeboot. It is the same hardware generation (GM45), with same CPUs, video processor, etc.
It is believed that all or most T500 laptops are compatible. See notes about CPU compatibility for potential incompatibilities.
W500 is also compatible, and mostly the same design as T500.
There are two possible flash chip sizes for the T500: 4MiB (32Mbit) or 8MiB (64Mbit). This can be identified by the type of flash chip below the palmrest: 4MiB is SOIC-8, 8MiB is SOIC-16.
The T500 laptops come with the ME (and sometimes AMT in addition) before flashing Canoeboot. Canoeboot disables and removes it by using a modified descriptor: see ../install/ich9utils.html (contains notes, plus instructions)
Flashing instructions can be found at ../install/#flashrom
It is recommended that you update to the latest EC firmware version. The EC firmware is separate from Canoeboot, so we don’t actually provide that, but if you still have Lenovo BIOS then you can just run the Lenovo BIOS update utility, which will update both the BIOS and EC version. See:
NOTE: this can only be done when you are using Lenovo BIOS. How to update the EC firmware while running Canoeboot is unknown. Canoeboot only replaces the BIOS firmware, not EC.
Updated EC firmware has several advantages e.g. bettery battery handling.
The T500 is almost identical to the X200, code-wise. See x200.html.
