And it doesn't get remounted read-write? I suspect one of three problems. To begin with the root filesystem is always booted read-only. This is done so that it can be fsck'd at boot time. Then after that point in the boot process the root filesystem is mounted read-write. I don't remember if it done with a remount or if it is just mounted on top of the read-write device. If your system is not transitioning through from read-only to read-write then something in that process has been broken. And there are many ways it may be broken so you will need to determine what has actually happened and fix it. You mentioned having a root filesystem entry in /etc/fstab so that isn't likely the problem. I would check that you haven't accidentally removed the startup symlink for the /etc/rcS.d/S*mountall.sh which IIRC will be the startup process that mounts everything including the root filesystem. Check /var/log/syslog for any error messages that might be a clue. Check the output of 'dmesg | less' for any information that might be a clue. If that didn't yield anything then I would boot into single user mode and manually run each startup script up through mountall.sh and then debug running that script to see what the problem is. I usually debug scripts by running them with 'sh -x scriptname' and looking at the trace output. > Then I restart the network and go back to level 5. You mean 2 sir. The normal Debian runlevel is 2. Runlevel 5 is used by some other distros. But you are running Debian, right? :-) Of course you could have edited /etc/inittab and changed the default. > All that did not make any difference.

Which kernel are you running? 'cat /proc/version' Because due to limitations of the original pc architecture a standard 32-bit kernel won't be able to use all 4G. If you are running a 32-bit kernel you will probably need the bigmem flavor. If you want a flat address space you will need to run the amd64 kernel. And again, the dmesg output will show the memory map. Bob
