What To Do When an Advised BIOS Upgrade Is Bad?
Bomarc writes "Twice now I've been advised to 'flash the BIOS to the latest,' once by a (major) hard drive controller maker (RAID); once by an OEM (who listed the update as 'critical,' and has removed older versions of the BIOS). Both times, the update has bricked an expensive piece of equipment. Both times, the response after the failed flash was 'It's not our problem, it's out of warranty.' Given that they recommended / advised that the unit be upgraded, shouldn't they shoulder the responsibility of BIOS upgrade failure? Also, if their design had sockets rather than soldering on parts, one could R/R the faulty part (BIOS chip), rather than going to eBay and praying. Am I the only one that has experienced this type of problem? Have you been advised to upgrade a BIOS (firmware); and the upgrade bricked the part or system? If so, what did you do? Should I name the companies?"
It's been almost 4 years since I built my last box. I'm planning on building another desktop this summer and would like to know who to avoid as I'm intending to purchase a motherboot that's supported by coreboot so I don't have to deal with UEFI. If there's a motherboard vendor doing evil stuff and they're listed I would like to avoid them if I can. Here's the link for supported motherboards: http://www.coreboot.org/Supported_Motherboards
System: Dell PE 1950; critical update for the BMC controller.
What's the failure mode on each of {the BMC, the PERC}? I have some experience handling failures of this nature.
In particular, it's been my experience that on some Dell models of that generation, if you update the BMC firmware without updating the NIC firmware as well, the BMC will fail to be reachable on the network. Fortunately a NIC F/W update fixes this readily enough.
I wish they told you that.

That is not at all the case. BIOS/firmware/driver updates/upgrades can potentially do four things for a working system:
1) Add new features. Many products get new features as their life goes on. My desktop board, an Intel, has gotten a number of new BIOS features during its life. When you update the code that runs something, no surprise that code can add features.
2) Improve performance. Sometimes, a faster/more efficient way of doing something is discovered. It takes an update to make that happen. I remember a big one back in the day with 3com switches. A firmware update provided a major improvement in through put and CPU usage.
3) Fix a bug that you haven't hit yet, but could. This is why you'll see updates tagged as urgent. Just because you never hit a bug that got discovered, doesn't mean the bug isn't there. So you want to get it fixed, BEFORE you hit it. There have been firmware updates that fixed some nasty ones, like data corruption with SSDs. Some people never got hit, but that doesn't mean the update wasn't a good idea.
4) Security issues. Same deal as with the bugs, just a different kind of bug. If a security issue is discovered, it'll take a patch to fix it and the system will be working before the patch.
The "Don't fix it if it ain't broke," really is not a valid ideology for systems administration.
This is one of the many reasons I order Dell servers.
One of the others being that their next-business-day 5 yr warranty really means next-business-day.
