We have a six disk array and had to configure one OUT of the array to boot RH 6.2. The other method is use a boot floppy (quite slow) or another disk that will show up BEFORE the RAID array. We tried using another disk to boot from but we could not get disk to show up BEFORE the RAID controller. We have the Adaptec 2940UW and Megaraid RAID controller combination. If I'm wrong here, someone please correct me. I would be happy to be able to boot from our RAID array. Hope this helps. Regards, Rich ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Richard R.

Linux Distribution RedHart ver 6.2 Disk partition: Root(/) Boot(/boot) home(/home)..etc. All with Raid1 configuration except swap disk. My problem is I can not install LILO on the MBR. It turns gray and can not be selected during insation. When I restart I have only "LI" display and the system stops. My question is, is there a limit for the HDD (81GB) that is preventing the installation? Or have I missed something somewhere? I made a boot disk (floppy disk) which I am using currently. I have no problem with the boot disk nor the system itself. Any help will be appreciated Mukaila
