I noticed nice command today, dmidecode. It tells lots of information about hardware from linux. I.e bios version and what kind of memory the machine uses:

[root@sirius ~]# dmidecode | head -n 13
# dmidecode 2.7
SMBIOS 2.3 present.
51 structures occupying 1436 bytes.
Table at 0x000F2F50.

Handle 0x0000, DMI type 0, 20 bytes.

The man page tells that you can also find information with prebuild strings like bios-version:

[root@sirius ~]# dmidecode -s bios-version

You can also query information with type. Like -t memory etc. Refer to man page.
