Try clearing CMOS before attempting it again.

Bad Bios checksum or Bios ROM checksum error or CMOS checksum error ?

If there's SETUP, it's probably CMOS checksum error.
Make sure the battery is OK and the clear CMOS jumper is set to NORMAL.

date changes back -> bad battery. usually a CR2032 coin cell.
