Checksum erro

[jamin123]

Soyo SY-7ISA+ checksum erro, default cmos load at boot, F1 or DEL to continue. I change the battery and clear CMOS. I tried to set the cmos time but the time sec. is racing it wont keep correct time. I set to boot from CD, but it reverted back to flopy. Every change I made doesn't save after reboot.
