The machine ran Windows without problems for a week now, and i left space on a 2nd partition onto which i wanted to install 2.0.5 today. When booting from the boot floppy, the install crashed or halted at several stages: - /: write: file system full - page fault while in supervisor mode - cursor in lower left with blue empty screen between pages, frozen - unable to newfs the disk due to wrong disk geometry - or simply just hanging somewhere in the menus It was really getting frustrating. Almost any time the machine froze, i was able to get a pop-up window when pressing CTL-ALT-DEL ("Do you want to exit installation ?"). I removed every unused driver booting with -c, no change. I removed every unused piece of hardware, no change. At a time when there was nothing more to change but the CPU and the memory, i replaced the memory - and - from then on i had NO problems installing 2.0.5 anymore. I could not believe it! I checked other SIMM's but all other ran, with parity, without parity and with dummy parity. The SIMM's which did not "run" were NEC chips, the ones which do run are Goldstar and TI, ALL (!) of them with the same access time of 70ns. I still cannot believe it ... Just a thought: in this situation i missed a menu item in the very first install menu giving me just a shell. (Yes, i know ...) Otherwise: very very well done! Congratulations core team! That must have been very hard and boring work, but once it works ;-) it's very nice! hellmuth -- Hellmuth Michaelis hm@altona.hamburg.com Hamburg, Europe (A)bort, (R)etry, (I)nstall BSD ?
