Update: I cracked it open and looked for a means to reset BIOS. I didn't see a separate CMOS battery, nor any button or jumpers, so I unplugged the battery for about 5 minutes.
That did the trick. I restarted an was immediately greeted by a backlit screen, followed by the BIOS splash screen. I went in, reset the system clock and all was good.
For the record, this was the change I'd made that caused all of the trouble:
Code:
Chipset
- South Bridge
- OS Selection
- Windows
- Android
- Win7
- Intel Linux
- MSDOS
The "OS Selection" option was set to Windows. I had changed it to Intel Linux on a whim (it was late). I'll need to research how and why that made a difference, but the bottom line is, it's been fixed. Thanks to all who provided advice.
This is an Aptio firmware from AMI.
Now about those audio issues...
