I want to share my discovery...
Was waking up an old console and attempted to update memory. Don't know what went wrong but the console did not like it. What happened was it refused to acknowledge any cards in the card cage I/O and EFX. Tried rebooting, reset bios, nothing worked thought it was toast. Then I decided to pull all the cards out of the console and boot up while empty. Shockingly it booted up even without a clock card. put all the cards back in and it boots up acknowledging all the card and all works well. Who knew!
