Any idea of the practical time differences between a CF x200 versus a

Under normal situations (where hardware handles talking to the CF device)
it should boot faster, as the sustained read rate is better and the
seek time is much lower [no physical movement]).

If you want to do the practical experiment most PCs can be persuaded to
boot directly from CF media. Dedicated SSD is faster still and becoming
increasingly affordable. They are silent in operation. Very useful if
you have huge multi-GB files requiring random readonly access.

Another quick and dirty test would be to put in a fast USB thumbnail
drive and let Vista put the fast boot image on it.

No way am I getting near Vista!
Anyhow, I only need to boot about 3GB
Either embedded XP or Linux

I'll try the USB flash expt though, since I've downloaded the netbook
version of Ubuntu which is designed to run from flash.

Can you do a core dump of this project when you finish? I have a G-job
where I need something similar.

I'll let people here know when I have done it, although from reading the
instructions on the Ubuntu site it seems very straightforward.http://www.ubuntu.com/getubuntu/download-netbook

If you do it before me post how it went please.

I'm waiting for the Nvidia Ion2. I may not get one, but I want to see
it before I pick some hardware. Unfortunately, I need windows due to
a critical program that doesn't work correctly in wine. [Before
FatLadyBoy starts up, we verified the problem with different hardware
and distributions.]

I use opensuse, but mostly because I'm used to it. Ubuntu is supposed
to be good. The only problem I see with Ubuntu for use as an embedded
OS is the upgrades come out too often. While there is a lot of "me
too" in Linux distributions, some of the flavors do have targets. For
instance Free BSD doesn't get large upgrades that often, so it is good
for servers. Open Suse has a time limit of I think two years on
support, so you either upgrade or you are on your own. There are low
latency distributions, etc.

Not if it's connected via an IDE adapter, then it just looks like an
old fashioned IDE drive with no removability. CF provides that mode,
so the adapter is just mechanics.

I did that and Windows still sees it as a removable disk. It has to do
with some bits in the identification.

Why do "webmasters" insist on links like that?

(PHP??) "developers" who don't know what they're doing.

is the upgrades come out too often.

10.04, due in April, will be a LTS version.

Most CF vendors will provide you with an app which changes the
removable/non-removable flag on the card. We use SanDisk and they were
very helpful with this in spite of the low volumes. They also sell
industrial-grade CF cards with the flag already set (amongst other
differences - longer guaranteed retention etc)

The other reason for marking the card as non-removable is AFAIK you
can't partition a removable drive using fdisk etc.

I have formatted removable drives and (HD like) media from both MSwin
and Linux. QED it is doable. Depending on the media you may have
to jump though some extra hoops. Also have done DVD-RAM, i have media
so why not?

What tools did you use? We tried DOS FDISK and Norton GDISK under
MSDOS, both won't partition the card until it has had the removable flag
set.

This was for a bootable CD-ROM which partitions the card, then loads the
OS and apps onto the card from a Norton Ghost image on the CD.
There are probably better ways of doing this, but it worked for us at
the time.
