99% of those IDE raid controllers are indeed NOT raid, but standard ide controllers that come with raid software. If this is the case(it is difficult to determine wether or not the controller is hardware sometimes, a good example is the Promise ATA raid controller you can turn a standard promise ata controller into raid by just adding a piece of circutry to it and flashing the bios. If your "raid" card is infact software based then it is not a "raid" card because the raid portion is all software, since linux already has raid builtin to it, you don't need the software even if you could use it on linux. 1) don't hold your breath on installing linux on an ide raid controller 2) You don't need to install the core OS onto raid -- more on this later 3) booting off a raid controller onto a raid set is extremely difficult and only possible with certain controllers. The problem - if the drives are in raid "mode", and the raid "driver" is loaded after the system boots(or more accurate while it is booting) how is the system supposed to boot off the drives if the driver is loaded yet?) This is possible using some hardware raid controllers(i've yet to see a ide raid controller that can stand up to a scsi raid, not only that but abit's quality control is crap) In the past i have configured a dual drive systems for raid1(mirroring). One system was IDE the other was SCSI. No raid controllers were used. what i did: 1) Setup identical partitioning schemes on both drives 2) Installed on drive 0, minimal installation 3) set up raid, rebooted so everything looked "good" on boot 4) finished installation to raid array the root filesystem(what cannot be on raid unless under very special circumstances) was only about 5megs. here is a good quality hardware raid controller: http://www.centrix-intl.com/ebay/2boxmegaraid428.htm Compare some of the features with the abit..id be very suprised if that highpoint raid chip was indeed hardware. nate -- ::: ICQ: 75132336 http://www.aphroland.org/ http://www.linuxpowered.net/ [EMAIL PROTECTED]
