Windows on (Sata) Raid 0, linux on PATA


i have windows installed on two drives in a raid0 setup..linux doesnt recognize these two drives as a single drives and i instead get

sda sdb

and i have another regular IDE drive : hda


ive heard that hardware raid on linux is a pain, and i dont really want to mess with the raid0 setup, so i want to install linux on the PATA..my questions are..

1) i want to install the bootloader on the MBR of the PATA drive..is this ok?

2) what options do i need to set in LILO so that it boots Windows properly...will

other=/dev/sda work?

if LILO cant do this , can GRUB or any other bootloader successfully boot the raid0 drive?

thanks!

Your setup is software RAID not hardware RAID. To get Linux behave the same as DOS/Windows, you have to use dmraid.

ok so with dmraid i have to activate a particular raid partition, it will get assigned to /dev/md0 and then i use this in lilo like so:

llo.conf

other=/dev/md0
label=windows

sorry im a bit nervous about doing this cause its my brothers computer..is this correct?

I suggest backing up the data if you feel unconfortable.

Hardware RAID is great in Linux, it's the BIOS assisted software RAID like you have that makes things difficult.

Sure, but you'll most likely have to setup the Windows bootloader to boot Linux too. That's probably the safer route, since I have no idea what how problematic installing LILO or GRUB into that RAID0 set would be.
