How can we find BIOS version from Linux Shell?
« on: December 03, 2013, 12:49:04 am »

We can find BIOS version for  Linux Box using the "dmidecode"command which is a great tool to analyse BIOS data. This command helps you to find out  the BIOS version without rebooting the server.

For example:

Code: [Select]
[root@s10 ~]# dmidecode --type 0
# dmidecode 2.11
SMBIOS 2.5 present.

Handle 0x0000, DMI type 0, 24 bytes
