I was always fascinated: why [some] people are dying to upgrade firmware?
It doesn't matter whether by firmware you mean system board BIOS, or
firmware of some card. Why taking chance having your machine hosed? If
current firmware version is crap, then you shouldn't buy any hardware by
this manufacturer in the first place. If current version is OK, why bother
re-flashing and taking chance to kill the [whatever] board. Beats me. The
only time I felt it justified was when new firmware [of 3ware RAID
adapter] was adding support for hard drives above 2TB capacity.

Can anybody offer an argument that can change my mind?


PS of course, yo can be that rich and have 3 redundant machines for
everything, so you wouldn't care about each particular one ;-)
