Looks like I've to do some more research what really is on my board first. Using the ISA-IO access method mbmon thinks I've a LM78 and mbmon even works but I'm getting false numbers for probably just everything... root@nudel xmbmon205> mbmon Temp.= 185.0, 0.0, 0.0; Rot.= 835, 30681, 18750 Vcore = 1.10, 1.81; Volt. = 3.39, 4.95, 8.21, -7.51, -3.24 ^C root@nudel xmbmon205> mbmon -d SMBus[NVidia nForce2] found, but No HWM available on it!! Using ISA-IO access method!! * Nat.Semi.Con. Chip LM78 found. root@nudel xmbmon205> When working with mbmon -S it comes to the conclusion that I have a lm75 (or maybe it thinks just that because it is the last of the supported HWM entries in the HWM_module array) but when probing it in lm75_probe it fails... i = set_smb_Extemp(LM75_ADDR_START, LM75_ADDR_END, &smb_wbtemp1, &smb_wbtemp2); temp1_flag = i >> 1; temp2_flag = i & 0x01; if (temp1_flag && temp2_flag) return 0; it returns 0 there and this is what probe_HWMChip does not like (it expects != 0). I'll go and find some information about what HWM chip is tied on that board...
