Hi, We are using RHEL 3.0 AS on an IBM x335m, CPU Xeon 3.06Ghz, with kernel 2.4.21-20.0.1.EL There is 2 x 256M + 2 x 2G of ram installed. The BIOS is counting 4608M of RAM, which is correct. RedHat only see 4G : titan# free total used free shared buffers cachedMem: 3989668 66544 3923124 0 8316 20852-/+ buffers/cache: 37376 3952292 Swap: 1052248 0 1052248 I added "mem=4608M" to my kernel line in grub.conf and rebooted but nothing has changed. I have another IBM x335 which has the exact same problem. Any idea ? Thanks and have a nice day, -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
