Message:

Remove the version 1 specifics part. It's very old and I'd hope
nobody uses this anymore. At any rate, there's little point in including
version 1 information in the version 2 FAQ. Set FAQ version to 2.18.

    1542 7 Version 1 Specific Questions 
    1543 ****************************** 
    1544  
    1545 Note: Version 1 is very very old and is not recommended. 
    1546  
    1547 7.1 My manufacturer swears that my mainboard has an SMBus, but your code reports that it can't find it.  What's wrong? 
    1548 ====================================================================================================================== 
    1549  
    1550 Currently, our code only assumes that an SMBus exists if it originates 
    1551 from the Intel PIIX4 (82371AB).  If your computer doesn't have one, or 
    1552 if your SMBus originates from a different SMBus 'host', then you are 
    1553 out of luck. :'( Our experience is, though, that most machines have a 
    1554 PIIX4, and that it is where the SMBus is hosted. 
    1555  
    1556    Regarding the VIA chip set(s): 
    1557  
    1558    Right now, the SMBus code depends on the Intel PIIX4 chip to handle 
    1559 SMBus transactions.  The VIA chip set is NOT supported at this time 
    1560 because it forces much of the SMBus protocol to be implemented by 
    1561 software. 
    1562  
    1563    To implement the SMBus correctly with the VIA chip, it needs to be 
    1564 written at a low level to be quick.  A more attractive alternative is to 
    1565 use the Bios SMBus interface (not always available nor standard). 
    1566  
    1567    Version 2 supports the VIA chipset, and will support other chipsets. 
    1568 Version 1 never will. 
    1569  
    1570 7.2 The modules won't load, saying 'SMBus not detected'. 
    1571 ======================================================== 
    1572  
    1573 This should no longer be an issue in 1.4.10 and later; it will continue 
    1574 loading, but it won't support SMBus-connected devices, of course. 
    1575  
    1576 7.3 I try to read `/proc/sensors', and I get a "No sensor data yet (try again in a few moments)" message. Why? 
    1577 ============================================================================================================== 
    1578  
    1579 It takes about 1.5 seconds for the LM78 to update all its sensor 
    1580 values.  If we would try to read it before it finished that, you would 
    1581 get old garbage instead. So you have to wait 1.5 seconds after the 
    1582 module is inserted before you can access `/proc/sensors'. 
    1583  
    1584    Module versions 1.3.7 and later let the process sleep if it tries to 
    1585 access sensor data right after insertion time, and do not display this 
    1586 message anymore. 
    1587  
    1588 7.4 On my Dell, a LM80 is detected, but all readings are 0! 
    1589 =========================================================== 
    1590  
    1591 This is a bug we have only observed on Dell computers. There is 
    1592 probably a problem with the way the SMBus is accessed; but it is not yet 
    1593 clear whether the problem is in our code or with the Dells. 
    1594  
    1595    There are very probably no sensor chips at all on your computer; but 
    1596 until somebody contacts Dell about this and tells us the results, we 
    1597 can not be sure.
