Error message on screen:

• Verifying DMI Pool Data
• This could indicate a bad hard drive, a main memory problem, or a CMOS memory problem.
  If it’s a CMOS memory problem, sometimes just changing anything in CMOS can clear the issue.
  Try this: turn the control off, then back on. As soon as you turn it back on, start tapping on the Del key (or the F2 key if you see ZF Micro). This should get you into the CMOS setting program. Once there, navigate to the date / time, and change the time, then press Esc, then F10 to save and exit. If you are unfamiliar with CMOS settings, click here for some example screens for reference.
  If the computer gets past the DMI Pool Data screen after reboot, you’ve fixed the problem. If not, it could be something else; email service@omniturn.com for advice.
• Goes partly through boot-up, then blinking cursor
• This could indicate a bad hard drive: change BIOS boot sequence
  To change BIOS boot sequence:
  Turn the control on and immediately start tapping on the Del key. Keep tapping on it until the CMOS settings menu appears.
  Use the Down arrow key to highlight BIOS (or ADVANCED, depending on your setup program) settings, then press Enter to go to the BIOS settings menu.
  In the BIOS menu, use the down arrow to highlight the Boot Sequence item, which is probably currently set to "C,A,SCSI". Use the Pg Up(coolant) key to step through the available selections until you get to "A,C,SCSI" , then press Esc to get back to the main CMOS menu.
  Press the F10 key to save the settings and exit.
