Hi.

I would like to know if it is possible to upgrade my Sony VAIO CR21Z BIOS, so that my laptop can support the Penryn 45mm 800 FSB processors, like T8100. Also it seems that my BIOS can't see more than 2GB of memory.

The laptop is based on ICH8 chipset so its not a hardware limitation.

The link of the BIOS is http://www.sony.co.uk/support/en/product...56269_3814

The next model, CR31ZR seems identical except that it supports Penryn and 4GB memory.

Thanks for your time.
Please, can anybody give an advice?

Just wanted to report that CR21Z works with 2x2GB memory.
Everything works fine.

I just installed a T8100 in my laptop which works, except that the
maximum reported frequency is 2GHz instead of 2.1GHz.
So, probably we need a BIOS update for correctly supporting Penryn.

I flashed a CR31z BIOS and now the processor is recognized correctly.
