<br>
It is just a wson-8 flash rom, whose soldering plates are
compatible with those for soic-8 chips, often found on thinkpads
produced when 8MiB soic-8 chip are hardly available.<br>
<br>
The common way to deal with wson-8 chips is to blow it off with
hot air blower, suck up its content, and finally replace it with a
soic-8 chip.<br>
<br>
There is an article mentioned wson-8 chips:

<pre wrap="">Hi list,
I don't know if it's common yet (the wiki article doesn't mention it)
but today I discovered that there are Lenovo Thinkpads with very flat
SMD-Flash-ROMs which make it impossible to access them with a SOIC-Clip
or flash them by soldering wires to the pins directly.
I aborted the flashing but am going to try finding a work-around.
About the laptop:
Type 4298-W28 S/N R9-E4CFC 11/06 (so probably manufactured in 2011)
Product ID: 4298W28
Maybe we should write one sentence in the wiki mentioning that not all
chips are accessable very comfortably.
Greetings,
P.
PS: Rantmode: Why the hell don't they just solder a socket? It's not
that unrealistic that someone bricks the BIOS while updating the
firmware from time to time. Being able to replace the ROM with a fresh
one is a huge plus.
