Different from what? You can use dd to copy partition table with right layout. Also 1st IDE disk is usually threated a bit different by partition code in order to be compatible with BIOS boot logic. If that's your problem, you can specify right geometry from "kernel command line" (append= in lilo) > > Second to you and Chris: > > Is it possible to boot from the mirrored RAID1 partitions (hdX10) with the > > current lilo-22.x (SuSE 8.0)? With ReiserFS? Should be no problem. Lilo does not depend on filesystem at all, it only records disk block numbers. It is unclear if you will be able to boot if first disk of mirrored set will fail, because you usually have lilo only on one of the disks, but if lilo is located on 3rd disk, then this will only work if you remove failed raid1 disk and second disk will get same bios id as first one had. (note I am not quite sure here, but it shold work this way. Also there might be a way to tell lilo about RAID1 setups but I've never saw this myself). > Is ReiserFS usable on such a system, too? Reiserfs is usable on any block device that correctly works from reiserfs perspective. (e.g. loop devices over samba do not work). Bye, Oleg
