FreeBSD is definitely the system that will make it through the apocalypse. A friend once told me he had a damaged RAM module, trying to install Windows, various Linux distributions, nothing worked. But it was possible to install FreeBSD and it just worked...
- asveikau 6y agoStill probably should get that RAM replaced though.
- fouc 6y agoNow I'm wondering how FreeBSD handles damaged RAM differently, and the speed hit it takes for doing so.
- toast0 6y agoTo my knowledge, FreeBSD doesn't have anything specific here, it was probably just luck in where the broken addresses fell and how they were used. These days FreeBSD and Linux both have provisions to avoid addresses you know are bad, if you tell them at boot (and if you don't need those addresses to boot). I'm pretty sure I've read that Solaris has provisions to stop using bad addresses detected at runtime, but it needs ECC or similar to detect the badness.
- bluGill 6y agoFreebsd used to be known as the most sensitive. In the 2.x days (late 1990) freebsd would fail to load on system with bad memory that Linux or windows had no problems with. In the end it is a good thing of the os refuses to run as no good can come of working with bad hardware
- ken 6y agoWhat mechanism is at work here? Do FreeBSD hackers write code that doesn't depend on RAM working?
- dbuder 6y agoHandles RAM setup differently, probably checks every block. I thought bios handled that but obv that doesn't help unless you are running BSD.
