Updating the BIOS
49
Using the Iflash Memory Update Utility
With the Iflash Memory update utility you can update the system BIOS from a
bootable USB flash drive or other bootable USB media. The Iflash BIOS update files
can be extracted locally to your hard drive and copied to a bootable USB flash drive or
other bootable USB media.
NOTE
Review the instructions distributed with the update utility before attempting a BIOS
update.
CAUTION
Do not interrupt the process or the system may not function properly.
1. Uncompress the BIOS update file and copy the .BIO file and IFLASH.EXE to a
bootable USB flash drive or other bootable USB media.
2. Configure the BIOS or use the F10 key option during POST to boot to the USB
device.
3. Manually run the IFLASH.EXE file from the USB device and manually update the
BIOS.
Recovering the BIOS
It is unlikely that anything will interrupt a BIOS update; however, if an interruption
occurs, the BIOS could be damaged. Table 16 lists the drives and media types that
can and ca
nnot be used for BIOS recovery. The BIOS recovery media does not have
to be bootable.
Table 16. Acceptable Drives/Media Types for BIOS Recovery
Media Type Can be Used for BIOS Recovery?
CD-ROM drive connected to the SATA interface Yes
USB removable drive (a USB Flash Drive, for example) Yes
USB diskette drive (with a 1.44 MB diskette) No
