I've verified that the EEPROM is generating data. I grabbed the data on the wire and decoded it. I've checked 2 different locations. (By hardcodeing the %bh value in the read functions) and in both cases I get back the data that I would expect.
BUT, the value returned back from the SMBHSTDAT0 register is zero. Heres and example out put of what I get. The SMBase: is some code I added to read back the register so I could verify that it was getting written. LinuxBIOS starting...

Could there be a setting in the southbridge that could cause this? Perhaps some sort of SMBus lockout register or some sort of timeing control? I've also tried a different board but got the same results. Sigh... Well off to bed. Perhaps I'll dream up an answer. -- Richard A. Smith Bitworks, Inc.
