Great! I've borrowed another PC with some 350GB to save my data and reconfigure my drive

Thats exactily what I would like to do! Great!
But is linux able to boot from this array? Do I need some special Software package installed for use md ?
I'm trying to install Yoper and the install CD is lacking most software. I'm in contact with the developer there and allowed to modify the install packages.

My Hardware: 4x160GB, (1hh ata for installing, temporalily ) My partition would be: - WinXP ( 10GB) - Linux1 ( 20GB ) - Linux2 (10GB) - Swap (2GB) - FAT32 ( 100GB) - /home (the rest)
Txs!
