This problem sounds very unusual to me. Also 288M seems like a lot of memory for the 770. After boot the 'dmesg' command will report memory information. That information will be logged in the /var/log/dmesg file. What information is logged there? Here is a sample from one of my systems: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000e0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 0000000007000000 (usable) BIOS-e820: 00000000fffe0000 - 0000000100000000 (reserved) 112MB LOWMEM available. ... Memory: 106320k/114688k available (1499k kernel code, 7864k reserved, 599k data, 256k init, 0k highmem) It would be useful to see the output from /proc/meminfo. In particular what does MemTotal show? In the above system with 112M the system shows the following. cat /proc/meminfo MemTotal: 110940 kB > I tried adding a boot parameter in GRUB using the mem command, but I > ended up with only 64MB after booting.

You probably want to try something more like this instead: mem=288M But if tell it more memory than you actually have available it will cause the system problems. This is documented in the linux source with various Documentation/* files such as boot.txt, kernel-parameters.txt, and memory.txt. A very good resource for ThinkPads is the ThinkWiki. http://www.thinkwiki.org/wiki/Category:770 Bob
