Dell Latitude E6400
===================
**If you haven't bought an T500 yet: the [Dell Latitude
E6400](e6400.md) is much easier to flash; no disassembly required,
it can be flashed entirely in software from Dell BIOS to nonGeNUine Boot. It is the
same hardware generation (GM45), with same CPUs, video processor, etc.**
Introduction
============
It is believed that all or most T500 laptops are compatible. See notes
about [CPU
compatibility](../install/t500_external.html#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 nonGeNUine Boot. nonGeNUine Boot disables and removes it by using a
modified descriptor: see [../install/ich9utils.md](../install/ich9utils.md)*
(contains notes, plus instructions)
Flashing instructions can be found at
[../install/\#flashrom](../install/#flashrom)
EC update {#ecupdate}
=========
It is recommended that you update to the latest EC firmware version. The
[EC firmware](../../faq.md#ec-embedded-controller-firmware) is separate from
nonGeNUine Boot, 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:
- [../install/#flashrom](../install/#flashrom)
