Hi All,     I downloaded the FEL live DVD yesterday, and tried it on my laptop, but
unfortunately found it to be too slow. It took a long time to boot from the DVD. Any
ideas.suggestions on how to improve the speed?
ThanksSandeep

Live CD/DVD is supposed to take time to boot even if you have a lot of
RAM and a high speed processor. The whole OS is read from the DVD and
loaded to RAM and then the OS runs from RAM. This reading and loading
of data from DVD to RAM takes a lot of time as compared to loading an
OS from hard disc since CD/DVD drive is  slow device, about 10MBps
(Hard disc can be as fast as 100 MBps or more) . So it is natural that
it will take time to boot. Once the OS is loaded, it will run smoothly
if you have more than 1 GB of RAM. If RAM is less than that, it will
be a bit sluggish but will still run.

P.S: You should not use the EDA tools in live mode because all your
changes will be lost. It is better to install it on your hard disc and
then use them.

Depends on what you mean by slow. It takes about 3-4 minutes or so to
get my desktop in Live Mode on a Core 2 duo 2Ghz, 1 GB RAM 800 Mhz
fsb. So calculate depending on your configuration.

Next, if you still feel the LiveDVD is taking too long, it could be
because its currently KDE based and KDE4.x had some problems of long
boot-up times (but was tweaked to restore sanity, according to what I
have read). So the only other option you have is to install them on
hard disk and switch to gnome or if you have bandwidth, Install a
default fedora OS and then group install FEL.

yum groupinstall 'Electronic Lab'

HTH.
