Building a fast computer

Hi guys,

I'm thinking about building myself a fast computer. I'd like to know how I could store the BIOS initialization for good so that every time I start the computer, it just loads this BIOS config in a blink of an eye instead of initializing everything over and over again. Maybe I could store it in an eprom or to a flash memory somewhere? Here's what I have in mind: Use a regular Ultra 360 SCSI 74GiB drive for documents, use a Gigabyte i-Ram 4GiB drive for the core OS (should load the whole OS in 2-3 secs maximum). So, basically I want to reduce the time between the moment I power on and the moment the computer starts loading the OS. I want to power on, and to see the desktop manager in 2-3 seconds. How could I do that?
Please let me know how you would do that. Also, if you have suggestions, please let me know!

I think you are greatly overestimating the speed increase you will get with the i-RAM. It is definitely very fast, no doubt about it, but some things during bootup are not taking a long time due to file access times, but rather the fact that they take processing power. Starting GNOME/KDE takes up a lot of CPU cycles as all those back-end daemons come to life. A fast storage media is not going to prevent that, it will just make it so the files themselves are more readily available.

So you will see an increase, but going from the bootloader to a KDE desktop in 3 seconds just isn't happening.

Thanks. I'm actually able to load the OS in 1-2 seconds if I but it in stand-by mode (everything is preloaded in RAM). The problem is if I shutdown the computer, I have to reload everything from the beginning, and the computer has to go through all the tedious and CPU-intensive tasks you just mentioned. Added up to the BIOS initialization. Here's a demo of the i-Ram:
It takes 3 seconds to load the OS after the BIOS initialization
Even with the quick-boot option in the BIOS and skipping the RAM count, it's still too slow.

I thought that the I-Ram and linux were not getting along?
