Yeah. 2010, and you want a 'secure' OS. Har har. I got yer 'secure' operating system:

"But know this, that in the last days perilous times will come: for men will be lovers of themselves, lovers of money, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, unloving, unforgiving, slanderers, without self-control, brutal, despisers of good, traitors, headstrong, haughty, lovers of pleasure rather than lovers of God, having a form of godliness but denying its power. And from such people turn away, for his name is Obama."

Need to set things up so that the hardware and installed software never is directly accessed by the users or network. Set it up as a virtual O/S that is not accessible by the outside because under the virtual system software the virtual O/S never directly accesses hardware or network ports. If the virtual machine O/S somehow does get infected or corrupted, simply shut it down and restart the virtual O/S. That part of the hard drive never touches the actual software of the bios or O/S software.

My first Tandy computer had DOS 2.11 built into ROM. Probably PROM, but it was pretty secure.

Put the operating system on a read-only card and plug it into the Mobo.

This research effort is designed to be more resilient and secure than either Linus or Windows.

Good to know. Really.

Linux. Why reinvent the wheel? Viruses and malware can't attack it.
