I try to install XP on a RAID 0/1 System (Adaptec 7902) on board.
RAID 0/1 has been properly set up with Adaptec utility tool (Adaptec BIOS) .
Utility says RAID is fine and active.

I loaded the appropriate driver (newest one from the Adaptec home page) when starting the XP installation.
As soon as the XP installer starts reading files from the CD, it reads approx. 100 files (into memory), the installation stops prompting that the next file could not be read from the CD. Indeed, the files already loaded in memory can not be flushed onto the disc.

Same happens when I try to install Win 2k.

Got an idea ??
