Hi, I have (new?) information about the PC87591x Super-I/O Chip. I have talked to Winbond and they said, the only way to access this chip is through the PowerManagement channels. The problem is, there exists verious firmware implementations, so (I think) there exists different commands through these channels. To support this chip, there are 2 possibilities. The first is we need to develope a firmware. The second is to analyze the firmware. On the Uniwill website, there is a reader/writer for this chip (http://www.uniwill.com/UserDownload/N243S/N243S2.htm), included in the BIOS Update archive and is called ecf11t.exe. And on National's page there is a programming reference for the core of the chip (CR16B). The datasheet is available at http://www.national.com/appinfo/compactrisc/pdf/cr16b-prog-ref.pdf. Have anyone an idea, how to proceed the support? I know, none of these possibilities are easy to manage. EnricoB
