System: Dual Pentium III - 667 MHz RAM 1 GB SCSI: 2 x 53C1010 (onbord) - 160 MB Disks: 3 x Seagate ST-318404 LW - 18 GB Problem: Installer report WRONG head/cyl/sectors for sda. It happened even with eide disk on other computer and I solved the problem appending "linux hda=xxx,xxx,xxx" when booting installer (pressed F1 etc.). Now it does NOT work with scsi disks... How can I tell my system the exact number of cyl/head/sec??? I should realize a software-raid-5, and I need to have three identical disks!!!! HEEEELPPPPP ;(( Claudio
