Modified BIOSes for Thinkpads

Always check the link to Lenovo's website and make sure the BIOS is meant for your machine. Though it shouldn't let you flash it if it isn't.

All downloads are bootable CDs (except for R32 – FL1 only), follow instructions from Lenovo's website on using bootable ISO BIOS updates.

Don't forget general BIOS flashing safety: never flash from Windows, remove the computer from dock, have charged battery and also connect AC power.
