I have come upon a project with some new (to me) M605s. Which generation of iDRAC is used in this system? I don't think it is iDRAC7 or iDRAC6. The firmware rev is 1.65, which appears to be the latest.  Would someone be able to point me to the manual for the right version of iDRAC? My project is to come up with a formula for how to use the iDRAC for remote console in 3 major OSes and 3 browsers. If there is any wisdom on this subject, I would appreciate getting ahold of that. Thanks.
