My usual procedure is create a dos boot diskette and run the mylex=20 configuration utility=20 (http://www.mylex.com/pub/support/current_raid/ezassist.exe) and create t= he=20 raid array within that. On some cards you have the option to press F2 (is= tr)=20 and configure from the cards bios but I have had problems with that in th= e=20 past. > In a other machine I have a AMI MegaRAID card and its working perfectly > with 2 18,4 gb scsi discs.

Or I have to do it from w2k?=20 The array is a function of the scsi card, not Freebsd or Win2k, although = see=20 man vinum and http://www.vinumvm.org/vinum/ for how to setup virtual arra= ys=20 within freebsd. In short, it depends on the card. > So far I > have not got very far yet, but I trying. I Have a w2k install on a junk > disc. I think it should be possible to join 2 discs to an array.
