I already looked into SuperoDoctor, but was not able to find this part. Hovewer I already assumed that it might be compatible and tested it yesterday (more below). > let confirm by: > Please provide output of > > lspci -v -v -v > and > lspci -n 00:02.0 Host bridge: Broadcom HT1000 Legacy South Bridge Subsystem: Broadcom: Unknown device 0201 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ Fast B2B- Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR - <PERR- Latency: 64 -n will tell you that it IS 1166:0205. > Maybe just adding the line with: > { PCI_DEVICE(0x1166, 0x205), > .driver_data = 0 }, > > Will do the trick. Assuming you have the "HT1000 Legacy South Bridge" If not we must find out where is the PCI id located and start from that point. this is exactly what I did: piix4_smbus 0000:00:02.0: Found 0000:00:02.0 device piix4_smbus 0000:00:02.0: Unusual config register value piix4_smbus 0000:00:02.0: Try using fix_hstcfg=1 if you experience problems piix4_smbus 0000:00:02.0: Illegal Interrupt configuration (or code out of date)! piix4_smbus 0000:00:02.0: SMBREV = 0x0 piix4_smbus 0000:00:02.0: SMBA = 0x580 after using fix_hstcfg=1, machine freeze... If you will have again a long time (just interested, what faculty and year, FEL ?) I will not leave the effort un-appreciated ;-) Going to dig into smbus.sys more for now. Martin
