Intel's datasheet for 82801IB (ICH9), 82801IR (ICH9R), 82801IH (ICH9DH), 82801IO (ICH9DO) I/O controllers hub (document #316972-02) 2. Specification update for the same hardware (document #316973-004) It seems the watchdog is implemented exactly the same way as for ICH8. So all we need to add the support for ICH9 into ichwd is: 1. add the following into ichwd.h: #define DEVICEID_ICH9 0x2918 #define DEVICEID_ICH9R 0x2916 #define DEVICEID_ICH9DH 0x2912 #define DEVICEID_ICH9DO 0x2914 2. add the following into ichwd.c: { DEVICEID_ICH9, "Intel ICH9 watchdog timer", 9 }, { DEVICEID_ICH9R, "Intel ICH9R watchdog timer", 9 }, { DEVICEID_ICH9DH, "Intel ICH9DH watchdog timer", 9 }, { DEVICEID_ICH9DO, "Intel ICH9DO watchdog timer", 9 }, I not only readed the specification but also tried the change on my hardware. It seems to work. >Release-Note: >Audit-Trail: >Unformatted:
