welll...... windows 9x has no drivers for nf4, so scratch the dual boot thing, after going to protected mode drivers, I loose my cdrom, so I can't add anything to the 9x install without using a USB drive.. I'll leave it there to get a command prompt if I need one, oh and nf4 raid drivers have to be installed at the beginning of xp install using the f6 and drivers on the floppy, not like adding a driver for a pci add-in raid controller after the OS is installed, which you could do on 9x... so one more time around Nforce4 nvraid kinda sucks..
