    4 It unhides the SMBus of Intel ICH southbridges hidden 
    5 on ASUS P4B series. It is implemented as a module (p4b_smbus.o), 
    6 or a shell script for the 2.6 kernel (unhide_ICH_SMBus). 
     4It unhides the SMBus of Intel ICH southbridges hidden on Asus P4B series 
     5and some other Asus and non-Asus systems. It is implemented as a shell 
     6script for the 2.6 kernel: unhide_ICH_SMBus. 
    77 
    88It works with the following chips: 
    99 * ICH2   (82801BA) 
    1010 * ICH2-M (82801BAM) 
     11 * ICH3   (82801CA) 
     12 * ICH3-M (82801CAM) 
    1113 * ICH4   (82801DB) 
    1214 * ICH4-M (82801DBM) 
    … …  
    1820Really funny :-).

    20 This module is for 2.4 kernels only. For 2.6 kernels, activation is 
    21 handled by the code in drivers/pci/quirks.c in the kernel source. If you 
    22 have the 2.6 kernel and the quirks code does not activate your SMBus, 
    23 you may: 
     22For 2.6 kernels, activation is normally handled by the code in 
     23drivers/pci/quirks.c in the kernel source. If you have the 2.6 kernel and 
     24the quirks code does not activate your SMBus, you may: 
    2425 
    25  * check if you have kernel version from 2.6.17 to 2.6.19 
    26    If so you, need to disable ACPI sleep support and recompile kernel.  
     26 * first of all, read the paragraph "Hidden ICH SMBus" in 
     27   Documentation/i2c/busses/i2c-i801 in the kernel source. 
     28 
     29 * check if you have kernel version from 2.6.16 to 2.6.19 
     30   If so, you need to disable ACPI sleep support and recompile kernel.  
    2731   If you don't use suspend try below instead of recompilation. 
    2832 
    … …  
    3438   try to fix the quirks.c, recompile and test your new kernel, 
    3539   and then submit a patch to us. Contact us if you need assistance. 
    36  
    37 Information for 2.4 users continues below. 
    38  
    39 NOTE: As of kernel 2.4.23, the kernel activates the SMBus PCI device 
    40 on the following boards: 
    41  * Asus P4B 
    42  * Asus P4B533 
    43  * Asus P4PE 
    44  * Asus P4T533 
    45  * Asus P4G8X Deluxe 
    46 So this module is no longer required for these boards. For the other  
    47 affected boards, it still is. 
    48  
    49 What does the module do? 
    50 ------------------------ 
    51 (Note: the following instructions assume the ICH2. For the ICH4, 
    52 the PCI IDs are 24C0 and 24C3) 
    53  
    54 It turnes off (!) the bits number 8 and 3 in the LPC register of the ICH2. 
    55 This you can also try as root with setpci and pcitweak. 
    56 First do a: 
    57  
    58 setpci -d 8086:2440 f2.w 
    59  
    60 You will get an hex number VAL - in my case 148 (Hex)-, where you have to  
    61 erase the two bits - in my case you get 40 (Hex). 
    62 Then do a: 
    63  
    64 setpci -d 8086:2440 f2.w=VAL 
    65  
    66 Running "lspci -n" you will not see any new device, but with "pcitweak -l" you 
    67 should get a line similar to this in the output: 
    68  
    69 PCI: 00:1f:3: chip 8086,2443 card 1043,8028 rev 12 class 0c,05,00 hdr 00 
    70  
    71 The important thing is the "8086,2443" here. 
    72 The device is activated, but not included in /proc/pci and  
    73 /proc/bus/pci/devices. This is the reason for running the module. 
    74  
    75 What are the system requirements? 
    76 --------------------------------- 
    77  
    78 - Obviously a board with Intel i801BA/DB/EB ICH2/4/5 with broken BIOS. 
    79 - A linux working with a 2.4 kernel AND hotplug support in it!  
    80 - A installed kernel tree and gcc. 
    81 - i2c and sensor modules installed. 
    82  
    83 How to install? 
    84 --------------- 
    85  
    86 Simply do a: 
    87  
    88 make -f Makefile.p4b 
    89 insmod p4b_smbus.o 
    90 modprobe  i2c-core 
    91 modprobe  i2c-i801 
    92 modprobe  i2c-dev 
    93 modprobe  i2c-proc 
    94  
    95 Then run your sensor: 
    96  
    97 modprobe  w83781d 
    98  
    99 What should i never do? 
    100 ----------------------- 
    101  
    102 Do not try to do a "rmmod p4b_smbus" before a "rmmod i2c-i801". 
    103 The other way around should be okay. Otherwise you remove the PCI device 
    104 without notifying the i2c driver.
