|I quite agreed with the statement "It's not a good idea to update the bios unless you have a very good reason for doing so" but in case there is a need to do BIOS upgrade either as a requirement due to a new system deployment, application installation or using new hardware on legacy PC caution has to be taken.|
1. Make sure appropriate BIOS application is downloaded from manufacturer's site.
2. Make sure the system is properly powered and there is battery backup in case of any power interruption.
3. All data is backed out.
Then you can go ahead.
NOTE: GUI applications too can be installed through DOS.
