Also, can you show me the appropriate portion of your grub.conf? I would like to see if maybe it is different than mine even though they are both pre-packaged installs. I had a machine with 2.6.20-2931.fc7xen, so I copied that to the machine in question, and it also only shows 3.1GiB for me. I compared the config files for that kernel and the one I was using, and they are identical (minus version and date comment lines), so that was as I expected, but it makes it less likely that my problem is a version problem and more likely that something else is haywire. Thanks, > Dustin My install command line was: ksdevice=eth0 console=tty0 console=ttyS0,9600 load_ramdisk=1 initrd=f7/x86_64/initrd.img network ks=http://ks/ks-f7-v40z.cfg kssendmac BOOT_IMAGE=f7/x86_64/vmlinuz My grub entry for the currently running kernel is: title Fedora (2.6.20-2931.fc7xen) root (hd0,0) kernel /xen.gz-2.6.20-2931.fc7 com1=9600 module /vmlinuz-2.6.20-2931.fc7xen ro root=/dev/VGRAID/LVRoot console=ttyS0,9600 module /initrd-2.6.20-2931.fc7xen.img My messy KS and KS post script is attached. During install, I did hit a bug https://bugzilla.redhat.com/show_bug.cgi?id=242107 that I had to work around by running mkinitrd before I rebooted. If I didn't I would be missing the RAID1 module and fail to boot, but that's not related to the memory issue. -- Dale Bewley - Unix Administrator - Shields Library - UC Davis GPG: 0xB098A0F3 0D5A 9AEB 43F4 F84C 7EFD 1753 064D 2583 B098 A0F3
