How to solve the start's problem of BS_I2cIo

Published: 17 Aug 2015 | Author: Mentor

BS_I2cIo is a driver provided by Biostar for its motherboards that has some problems with the OS x64 and in the Event viewer we have this message:

The following boot-start or system-start driver(s) failed to load:

BS_I2cIo

The problem is caused by a wrong path in the registry keys:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\BS_I2cIo

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\services\BS_I2cIo

where the path points at the file:

C:\Windows\System32\drivers\BS_I2c64.sys

instead of:

C:\Windows\SysWOW64\drivers\BS_I2c64.sys

Editing the path in the keys we will solve the problem.
