• Disable power settings, screensaver and lock.

===========================
Trial 1, Preliminary

• removed e.data and bd.data to force reconfiguration of bpc.
• configured "Bayou Black" BBS
• No sound
• Full Screen (alt-D) with decorations (alt-B)

• Time Test - allowing board to idle while running, no network transmissions for about 3 hours to witness time drift.
  • Start 3:33 am
  • Stop at 5:05 am.
• Test was stopped as there was no time drift (difference between the NIB clock and the host clock for over 1.5 hours. Additionally, all witnessed cpu speeds were a constant 100%.
• Configuration and addition to network.
• Running with a configuration, system is between 80-100%. Not acceptable. Going to retry with a lower resolution.
• set to 640x480, took aspect true off, set rendering to nearest neighbor. dropped to 99% during startup.
  • • I think I may have a winner. Need to set up subs and get it going for the next test of a live setup. I see no point in testing x64sc until the subs are setup. I wanted to do prelims to see if I could get the board to idle at 100% using xscpu64. x64sc historically has been less resource intensive than xscpu64.
