I have a box (800 Mhz Duron) running RHL 9 with up2date up to snuff. I want to upgrade the memory to 512 mb. When I put in the new memory board, It begins to boot up to the messages: RAMDISK: Compressed image found at block 0 VFS: Moutned root (ext2 filesystem). It then hangs. It is past where you choose the kernel but before the nicely colored startup service messages begin. I have tried both adding a second 256 MB board and putting in a 512 MB board by itself. Could there be something I need to add to the grub.conf file or some other file to tell Linux that there is more memory? The data does not get saved in dmesg or messages as I end up having to power cycle the machine. Is there some other file that may reveal useful clues? Thanks for any advise. Robert E.
