Hi all, I want to write a device driver for my ethernet card supporting APM. apm --debug shows APM BIOS 1.2 (kernel driver 2.2) . Can anyone tell me what are the * entry points * with which my device driver can communicate with kernel apm driver to support the apm facility for the ethernet card? Please reply soon. Im new to apm concept and got confused in it. Thanks in advance, Regds, Manish
