Slow CardBus/ExpressPort performance on your Thinkpad T61/X61? Update your BIOS!

One reason, besides not off lease yet, I have held onto my Thinkpad T60 due to the reported speed problems with the CardBus/ExpressPort interface of the T61. It has been widely reported, mainly here and here.

Well, in June, Lenovo released a BIOS update with a very interesting changelog, as noted here:

This issue appears to have been resolved with the bios update released on 6/11/2008 (version 2.19-1.08) Speeds have gone from an average of 14 MB/s to about 60MB/s.

The changelog entry: "(Fix) Some CardBus and IEEE 1394 devices may slow down the performance."

You can download the new T61 BIOS here and the new X61 BIOS here.
