Multiple devices driver support in kernel?

Hello Linux folkz, I'm trying to setup RAID0 However, in a plain kernel 2.4.3 configuration I can't see 'Boot support' and 'Auto Detect support' in 'Multiple devices driver support (RAID and LVM)' section. Could somebody enlighten me how to enable these features in a plain vanilla 2.4.3 kernel. What patch should be applied if any? Thank you in advance.
