My new Windows 7 installation is working well.
I believe that Windows 7 and higher does not allow my 2 DVD-ROM drives to be shown along with C drive and other disk drives as part of "Computer" when in Windows Explorer. (I remember that Windows XP allowed this feature.)
It is not a problem since both drives work fine. I only thought that Windows 7 would show them both, but it doesn't.
Other than that, everything is working well. Thank you again for your help in the installation of Windows 7 and the required drivers.
