Hello Nihil,

Ok, yes, your assumsion that they drivers are 4GBs is correct (4.3 to be procise). The BIOS does see the drivers as well. All drivers light up and are recognized by the array. The 4GB part is where I can install my OS (windows 2000 server) and the rest disappears.

I've gone through the array setup (several times) to ensure I was putting it at Raid 5 (had choice between 0,1+0,1,4,and 5) and once done, save configuration to the controller and reboot to install the OS. Raid 5 is suppose to be 80%write and 20%guard for datatransfer in case a drive fails, giving me 16GB of accessible memory and 4GB for failure (yank a drive and replace with a new one for rebuild), but I get the reverse?

Hope this explains a little better?

Thanks for looking
