I got the same "Panic: Not enough memory for root partition" message when installing MINIX 1.5. The reason I got it may not have been quite the same as Vernon's. However, since the problems are so closely related, I think it might be worth describing what I was doing wrong. Like Vernon, I have an AT clone with 1 meg of memory. After reading the MINIX installation instructions, I opted to set up /dev/hd3 as a 512K RAM disk image of the root file system. Doing this, I got the panic message on boot up. After looking through the code I realised that the mm distinguishes between the 640K regular memory and 384K extended memory: it doesn't like to allocate a block of memory across the boundary. So the 512K of memory I was asking for was being taken out of the 640K regular memory, where there wasn't enough available. I'm now less greedy, and just ask for a 384K RAM disk image; this just uses up all the extended memory, and everything works fine. Ross Beresford rberesfo@cix.compulink.co.uk
