This is Lenovo ThinkPad BIOS. Changelog: - Disabled whitelist check. - Enabled SATA II full speed. - Added SLIC 2.1 table. - Removed "Thermal sensing error" boot message (Penryn CPUs). - Added dual-IDA support. Version 2.29-1.08 BIOS: 2.29 / ECP: 1.08 Supported ThinkPad systems: - R61 (14.1 inch widescreen models with IEEE 1394) - R61i (14.1 inch widescreen models with IEEE 1394) - T61/T61p Note: You can choose "BIOS update + CTRL-FN swap" version of this BIOS if you like CTRL-FN swap. Updating the BIOS: 1) Run WINUPTP.EXE as administrator. 2) Select 'Update ThinkPad BIOS' and follow the instructions on the screen. 3) After the update has been completed, the program shows a message 'Flash Update has been successfully completed...'. Follow the instructions on the screen to restart the computer. There is no BIOS update for T61/T61p which you can flash under 64-bit Windows. Lenovo recommends the following: "If Windows Vista or 7 64-bit is already installed on your system, then you must use the bootable CD ISO format of this BIOS update". Bootable CD-image is included in this package. Important note: When you boot from this CD, BIOS update will start automatically. Pay attention that there are two ISO images (#1 and #2) for the CTRL-FN swap version. Use "#1.iso" first. If the CTRL-FN swap works properly after applying ISO #1, then everything is OK. In case ISO #1 flash is successfully completed but the CTRL-FN swap doesn't work, you have to use ISO #2.
