i got a dell e4310.i replaced the cd-burner with a hdd bay and a 7k500 hdd. the dell limit the raid level to raid 1 only,which is more flexible but not efficient. i just want to use raid 0.it is limited in bios,could any one help me to mod a raid 0 bios?thanks. the latest bios version for e4310 is a05,download address is ftp.dell.com/bios/E4310A05.EXE. i have tried the -writehdrfile or -writeromfile,nothing occured.
