Set-up of Fedora 8 on Dell Latitude D820

Alex Barnett, 1/17/08

If you want to understand the dual-boot config and partitioning first see my notes on the setup under Fedora Core 5

Hardware & status summary


I did a "Custom install" from DVD-ROM, which allowed me to preserve all my previous partitions (described in setup under FC5), apart from / and /boot which I wanted it to wipe clean and do a fresh install. In anaconda partition table editor, it was weird that I had to copy the LABEL information over to the mount points, since anaconda didn't know where any of the mount points were supposed to be.

I chose to customize the installed software choices based on prior experience.

For the dual-boot setup: Once F8 installed, boot from DVD/CD into read-only rescue mode, grab the boot partition start via,

dd if=/dev/sda3 of=linux_bootsec.bin bs=512 count=1
and scp linux_bootsec.bin somewhere. Boot up windows and scp it back to C:\, then edit the XP bootloader (after taking a backup of the file), boot.ini (which need to make visible via attrib -R -S -H C:\boot.ini from a command window) according to this guide. I changed the timeout to 3 sec, and made linux the default. There seems to be no problem with the BIOS 1024 cylinder limit (8.5GB) since my linux boot is over 10GB into the drive.

nVidia drivers

Download the latest driver (1679.07) from nVidia, put in /root/ and install as usual after any kernel changes. Here's my xorg.conf

Power comsumption

By checking /proc/acpi/battery/BAT0/state (takes 5 sec to update) you can compute power consumption in various states:
CPU0,1 idle (both 1Ghz)    wireless on      LCD max brightness            22W
CPU0,1 idle (both 1Ghz)    wireless on      LCD min brightness            17W
CPU0 100%, CPU1 idle       wireless on      LCD max brightness            26.5W
CPU0,1 both 100%           wireless on      LCD max brightness            33W
CPU0,1 idle (both 1Ghz)    wireless off     LCD max brightness            21W
So wireless consumes about 1+-0.2W (regardless of transmitting or receiving). LCD brightness range accounts for 3W, and both CPUs maxing out increases consumption by about 50%. Power consumptions are similar to the i8100 which only has one CPU.
