Hi everyone. Got a two part question here if anyone would be so kind as to sort me out with answers.

1.) Is anyone using a SATA based DVD-RW drive and this board? One from Pioneer perhaps? I currently have an IDE based Pioneer 112 but it no longer reads or writes CD's so I am wanting to purchase the SATA variant of the drive to use on this board. Has anyone had any issues with SATA optical drives not be recognized during post, not being able to be used to boot from during post and/or any issues using them in Windows for reading/writing? Does it matter which port it is used on if it does work well? I was hoping to keep it on the Intel ICH9R controller and disabling the JMicron controller altogether if at all possible. Any feedback would be appreciated.

2.) Has anyone noticed any stability differences in running 4GB of ram on XP Vs. Vista? I ask because 4GB on my current XP SP2 install is running fantastic (so far) but then again XP doesn't use anymore than 3GB at most. I am worried if going to Vista is going to compromise the current stability I am enjoying with 4GB due to the fact that Vista will actually use the full 4GB of ram. I hope I am wrong but I am thinking XP is easier with 4GB of ram since not all of it is being used. Anyone care to comment on this?

Thanks as usual.
