Folks

A Noob question. I have a 256 MB IDE DOM on a neoware 5000 machine. I used an IDE card on the PCI and hooked up a CD drive to boot into DSLinux and then wrote the latest img using dd and bs=16k. replaced IDE card with another intel 10/100 and I have an awesome silent router that rock solid reliable for my home.

Since we play a  lot and keep making frequent changes to Config file for fun, I wonder if the flash memory to give up after a few write cycles.

Is there a way for m0n0wall to tell it to use the full 256MB space so that even if we make some memory spots bad, it can find ample memory locations elsewhere to keep wring the config file changes.

Again, what a great product and kudos to its creator(s).

Most flash devices have wear levelling - that is they spread out writes over the whole flash area and remap it. If you write to the one address over and over again on disk, the writes will actually go to different cells on the flash.

So, you should be OK if the flash you're using has anything more than a very basic controller.
