This post is being made from my Arca OS installation on my 2007 Toshiba notebook. It doesn't recognize the WiFi card, and I haven't tried using an external monitor yet, but everything else was identified. I had some difficulty deleting the existing partition from inside the Arca OS installer, but after rebooting 3 or 4 times and trying different options, I finally got it to completely delete the partition and install from an empty drive.
I'm very pleased. I'm looking forward to getting some development software installed.
UPDATE: I was able to hook up my external monitor, and it's running in 1920 x 1440 mode. Very pleased. I've never gotten it to work on that mode in Windows before. Only 1920 x 1200.
Thank you,
