I am posting for dallen, since he has set his yubikey to static password mode, and this forum is impossible to use without a yubico-programmed key. Below is my (slightly edited) transcription of his help request:

I purchased the Yubikey to use as a static password token with TrueCrypt's pre-boot authentication. The Yubikey does not seem to function during the pre-boot stage. I get nothing out of the Yubikey except a continuous and perpetual flashing green light.
The problem occurs during TrueCrypt's pre-boot screen which is prior to the OS booting. My laptop is a Voodoo (prior to being acquired by HP). It has an Intel Centrino with 2 gigs of ram and a 100Gb harddrive. The BIOS is called Insyde.
My desktop is a system that I built myself and is fairly new. It has an EVGA motherboard (122-CK-NF68-A1) that runs Phoenix BIOS and has the 680i chipset. It has 4Gb of Corsair Dominator RAM. The processor is an Intel E6600 Core 2 Duo. It has an EVGA e-GeForce 8800GTS 640 MB graphics card (640-P2-N821-AR).
Regarding how TrueCrypt is set up, I have version 6.1a with whole drive encryption on the system. Therefore, when you power up the system after the BIOS initiates you are greeted with a welcome screen that asks for the password. If you fail to input the correct password, the system does not boot. If you enter the correct password, the decryption is done on the fly and the system boots. This is the stage that I would like to utilize the Yubikey.
Currently, my USB keyboard on my desktop allows me to input text. However, booting that same system even with the Yubikey inserted into the same USB port that my USB keyboard was inserted yields no output from the Yubikey upon prompting with my finger.
If there is any additional information that will be of use, please ask.
