Certainly the last: it is me who is scared to take 1:10000 chance. Speaking of Dell: we use only lowest end of their boxes (think 32 GB quad core CPU _Desktop_ today) which are en par with others price wise, yet very reliable. Never had to flash BIOS on these, and never had one failed because of me not having BIOS updates flashed routinely... As far as servers are concerned, these are tyan mostly. I do not re-flash their BIOS routinely. (And I doubt they release tons of BIOS upgrades, at the very most one per board during its lifetime which never sounded "do it or your box is dead tomorrow".) So, I maybe flashed BIOS 3-4 times per maybe 200 machines... Never had box bricked due to flashing. (Still...) And never had failure due to not doing "preventive" re-flashing. But after all: maybe I'm just extremely lucky ;-) and at the same time awfully scared (to fix something that shouldn't be broken IMHO).
