	Yes but it may not be useful. Bios isn't reentrant and the Unixes and
I expect windows bypass bios and go directly to the hardware. A hardware key
logger attached to the TTL input line from the keyboard connector on the 
motherboard will work just fine with any OS however. He (or she) who controls
the hardware controls the security ...
