I'd be surprised if 5.0 could boot in 4MB in a useful form, even after a custom kernel was built. > I've never had any luck below 8MB. > > Jason Burgess The only documentation on this that I see is in the FAQ. The FAQ only refers to 2.x, 3.x, and 4.x anyway. I'm not sure what the doc project has in mind for 5.x documentation. I received another email that said he was not able to install 5.0 in less than 20 MB, so there's a data point. Anyone want to take this up with [EMAIL PROTECTED] It seems this is a FAQ, but would be well to place the minimum memory requirements in the install instructions since no one reads the FAQ it seems.

You certainly shouldn't be running memory-hungry suites like GNOME or KDE on systems with minimal memory.

We're pretty sure that we can no longer install in 8 MB. It's possible that it would work in 12 MB, but where do you find systems with that amount of memory? >> What was it like back then?

Well, sure, but that has a meaning. There are a number of applications, notably in networking, which don't need much more than minimum memory. As I observed above, you're not going to run X with a bloatware desktop on it. Expect to use at least 64 MB for that. > If you want to use it for something real, then you need more.

You need *much* more memory for Microsoft-like programs such as newer "desktops" and OpenOffice. I did some research on this while writing the relevant chapters for the fourth edition of "The Complete FreeBSD", which should be out soon (http://www.oreilly.com/catalog/cfreebsd/index.html). I had intended to describe only KDE or GNOME. After seeing how much memory they used and how little advantage you get from it, I added the alternative of fvwm2. It's not as easy to configure, but it runs in about 5% of the memory footprint, and it gives you just about all the functionality. > If you want to do a buildworld, you need Y MBs.

well, but if you try to use GNOME... with 32MB it took my Pentium 133Mhz PC 30 minutes to load the environment!

They are basically what you need to just run the system. If you want to use it for something real, then you need more. How much more depnds on what you want to do. For example, to use X-Windows, you need 50-64MB just for X. If you want to do a buildworld, you need Y MBs. You need Y MB to run an application. If you want to do all of the above at the same time, then you have to assign values to Y and add what is appropriate together. I think the smallest machine that I used and didn't see a lot of swapping was 128 MB. Swapping drops your effective memory speed from 8ns to 8 ms. That is hard to over come with any OS.
