Is this still needed these days? >=20 My "server" has a consumer-grade desktop amd64 mobo, with all that implies about cheap hardware and strange/misleading bios options. It also has an add-in dual IDE card with the main data on raid1. It's set to ide=3Dreverse, without that it doesn't boot (the add-ins are IDE, system drive is SATA, so I guess it probably tries to boot from the DVD - it's been a long time since it bit me and I don't remember the full details. That was how it was set for 2.6.18.6, and how it now boots from 2.6.22.18. I think at one time the order of the interfaces might have been different. Certainly, I carry forward a fallback without ide=3Dreverse in lilo.conf, just in case the disks move on my next kernel upgrade. What a distro selects should cover most of that distro's users, but that is not anywhere near providing 100% coverage for *all* the hardware out there. Also, you can force your users to e.g. mount by label. So far, that hasn't been forced on me, and I really hate having to reboot that box :) Ken --=20 das eine Mal als Trag=F6die, das andere Mal als Farce
