SMBus Support in Windows XP
In the Windows DDK there is mention of support for SMBus and references therein
to Microsoft system drivers smbclass.sys and smbhc.sys. I can find no
reference
on the web or on any systems related to these drivers. Will they exist at
some future time?
Intel provides an SMBus device driver which they provide no documentation for
coding on their website. Please correct me if wrong here. Have seen
references to utilize the SMBus specification (1999) for API related
information. Is the Intel driver supporting the SMBus specification?
Would like to be able to detect and enumerate the devices attached to the
SMBus
as well as query information from them including battery information.
Thank you,
Ed R
