Hello All, I have 2 SATA disks in an Intel Matrix RAID setup. It contains two volumes, one in RAID1, the other in RAID0 configuration. These I created using the Option ROM of the motherboard, partitioned using cfdisk, and finally assembled into RAID devices using mdadm v3.0.3. As such, I obtained the following devices: /dev/md127 (the container to which /dev/md/imsm0 is pointing) /dev/md126 (the RAID1 "Volume0" pointed at by /dev/md/Volume0) /dev/md126p1 (the first partition intended to serve as the root fs) /dev/md126p2 (intended for user space) /dev/md126p3 (intended for swap) /dev/md125 (the RAID0 "Volume1" pointed at by /dev/md/Volume1) /dev/md125p1 (intended for user scratch space) /dev/md125p2 (itended for swap) (the long names came from mdadm v 3.0.3). If I boot from my USB memory stick, and make a stop at the grub shell, I can see all these partitions listed as (hd1) (hd1,[123]), (hd2) and (hd2,[12]), while my USB stick comes up under (hd0) and (hd0,[12]). Therefore, I would dare to say that grub does detect these devices. I tried to install grub 1.97.1 on /dev/md126 by countless ways without success. The command $ grub-install --modules=raid /dev/md126 for example returns the error message $ grub-setup: error: no mapping exists for "md126" The /boot/grub folder got created correctly, but the "device.map" file does not mention any virtual RAID devices. It reads: (hd0) /dev/sda (SATA1) (hd1) /dev/sdb (SATA2) (hd2) /dev/sdc (USB flash memory stick) which, by the way, does not resemble what the sh: grub> ls command returns before booting (see the list described before). Do I need to give up using "fake RAID" and turn to pure SW RAID to get the system up and running, or is there a way to install GRUB2 in this configuration? Your help is much appreciated. Thanks ahead, Tibor
