Use the following steps to update your NEC Versa 6220/30/60 system BIOS with the BIOS

tomer Service and Technical Support at (800) 632-4525, Fax (978) 635-4100.
You should only use the BIOS upgrade diskette for your specific model.
Updating the BIOS involves the following procedures:

tive can help you determine this.
