So I know someone who has two drives in a SATA RAID 0 stripe, using a Silicon Image 3112A chip (which is fakeraid), and was wondering if anyone with Linux raid experience might be able to offer anything. He has Windows XP installed currently, and might be interested enough to install Ubuntu if it can dual-boot, but has given up because the complications introduced by his RAID setup were too much. Is there a way to get Ubuntu to install dual-boot on a system like this? Are there drivers available in the Ubuntu installer that support this chip? If so, exactly what would have to be done during install to get them running? He tells me the Ubuntu installer didn't work in the normal way, I think maybe it didn't automatically detect his partitions. As I understand it we can't use Linux's software raid drvier 'md', because this would require us to delete the current 'fakeraid' partitions, destroying his data, and in any case there's no way Windows is going to run on Linux partitions so dual-boot would be impossible. If there is no driver in the Ubuntu installer, then I think our options are: 1. Install Ubuntu on some other, non-raid volume, then install the needed raid support, then migrate Ubuntu. Sounds pretty troublesome, I don't think he's willing to go to so much trouble. 2. Rebuild the Ubuntu installer with the necessary raid support, then install. I have no idea what would be required here or how to rebuild the Ubuntu installer. 3. Switch the bios to ATA, install Ubuntu, then install the raid support, then switch the BIOS back. Not sure if this is possible or not. Would this work in the dual-boot situation? Thanks for any input.
