Inside Lenovo ThinkPad W500

I really dislike 16:9 screens, so I am sticking to my Lenovo W500 with 1900x1200 screen resolution. But I'd like to tune it. That's not that easy, since there is not that much information in the web.

max CPU = QX9300?

The internet research shows: the QX9300 is not supported. There is no information whether it's a hardware limitation or it's the BIOS (similar as the other hardware white lists).

Roger and over?

Never give up never surrender!

If the it's a BIOS limitation, let's linger a bit.

BIOS

The BIOS of the Lenovo ThinkPad W500 resides inside a Macronix MX25L6405 which is a 64MBit serial flash memory.
The chip is soldered and sits beneath the CMOS battery plug and the DRAM slots.
So you either have to unsolder it (ick!) or connect it somehow. I'll try to use some probes to connect the chip to a Willem EPROM Programmer which I used already to program some Amiga 1000 Kickstart EPROMs. Best is to use Windows XP to run the software - you can't use Windows 7 64 bit!

Before I start to possibly kill my laptop, I'll use a separate chip.

... more if the chip arrives :-)
