T New features or options
T Restore a BIOS when it becomes corrupted.
Use the Phlash utility to update the system BIOS flash ROM.
NOTE: If you do not have a crisis recovery diskette at hand, then you should create a Crisis Recovery
Diskette before you use the Phlash utility.
NOTE: Do not install memory-related drivers (XMS, EMS, DPMI) when you use the Phlash.

contain enough power to finish BIOS flash, you may not boot the system because the BIOS is not
completely loaded.
