I am running a eee pc 1005peb with the n450 Atom, 1 gb ram, 250gb HD with 10.04LTS(because windohs 7 blows)
What I am wondering is because I have the express gate button does that force the bios to load a certain partition in the drive? I have fully formatted the drive when I did a fresh 10.04 install. Also I am big on music and was wondering if I could make a simple linux OS that would load from the "express gate" partition but would be severely limited to only music access with hard drive spin down, loading 100+songs into ram and other limitations to fully optimize battery life. As it sits I have a literal battery life of 6 hrs and would like to get like 11 of pure music with a fast boot time.

Express gate = asus rebranding of 'splashtop'. Its not a on a HDD partition, its a surface mounted flash drive-

It is possible to mod expressgate, eg-

WARNING! I have not tested any of these mods.

But its not going to help you....if your HDD spins down, how will you get your music?

can you copy them into a temporary fake partition created in ram? I would assume kind of like the opposite of a swap space.
I had a sony cd player that used to load quite a few tracks of a song into ram(i guess) and then spin down the cd. I could drop the cd player from 4 ft and it would never skip

I don't know much about Splashtop, but most Linux distros have /dev/shm available to use as a ramdisk. If you copy your stuff to there, it's in RAM, not your hard drive.

But you've only got 1GB of RAM to play with, so it's debateable whether a ramdisk would reduce disk usage much, since the more you fill up your RAM, the more likely the system is to start swapping to disk (assuming Splashtop swaps to disk that is...)

Well I have considered upgrading to 2 gbs of ram anyways. As it sits my ubuntu 10.04 uses about 245mb of ram at idle. I figure with a stripped down os with only the required programs and a simple to use mp3 player I would have ample amounts of extra ram to pre-load at least 1gb of music(if expanded to 2gb)(which is more than half of all that I have.) im just not sure if it's possible. Unfortunately I am not that inclined to figure it out myself :(

You simply arent going to double your battery life just by makign a RAM disc.

The HDD probably drags 1-1.5watts at idle, 1.5-3watts reading or writing. Considering that your eee pc 1005peb is around 20watts idle, 26-28watts at load, disabling the HDD would save you 10% or less of your power consumption.

You might go from 6hrs to 7hrs, but thats at best.

I'm not being a smart **** here. But wouldn't it be simpler to use extra battery packs or a larger capacity battery pack?

If the mfgrs. battery packs are too expensive, pick yourself up a Deep Cycle Marine Battery (gel cell, motorcycle battery size, 12 to 15 bucks) and use your DC adapter cord.

I had a couple of laptops where they wanted over 50 bucks for their scrawny short lived battery pack. Since I had the carry case already and the Gel Cell Battery fit into it nicely, I was never without power.

But I still prefer a REAL computer, which can be made portable easily enough if need be. AKA Bag computer!
