Currently, only smbus controller 46function is implemented. But it also have bus idle monitoring function. It 47will display mapped I/O address for bus monitoring function when attaching. 48 49.Sh SEE ALSO 50.Xr smb 4 , 51.Xr smbus 4 52.Sh HISTORY 53The 54.Nm 55manual page example first appeared in 56.Fx 3.0 . 57.Sh AUTHORS 58This 59manual page was written by 60.An Takanori Watanabe Aq takawata@shidahara1.planet.sci.kobe-u.ac.jp . 61.Sh BUGS 62This device requires IRQ 9 exclusively. To use this, you should enable 63ACPI function in BIOS configuration, or PnP mechanism assigns conflicted 64IRQ for PnP ISA card. And don't use IRQ 9 for Non-PnP ISA cards. 65
