Hi All, I have a HPT370/372 RAID controller and i want to install RedHat Linux 7.2 on my system. I selected RAID 1 in HPT-BIOS setup screen. I started up the installation and by typing "expert text" i went to Driver Disk menu. RedHat installation installed my HPT370/372 driver from floppy which i downloaded from their website. Next i chose Disk Druid and that shows my hard disks as follows: /dev/hda # Primary Channel - Master /dev/hda1 # / Partition /dev/hda2 # Swap partition /dev/hde # First hard disk which is part of RAID 1 configuration /dev/hdg # Second hard disk which is part of RAID 1 configuration /dev/sda # SCSI emulation of RAID 1 Now i created partion on /dev/hde and selected mount point as /usr. I selected Grub. When i continue with installation my hard disk gets formatted. I chose ext3. But.......... My installation stops. I get folowing errors : (4)ide-dmaproc : chipset supported ide_dma_timeout func only: 14 hde: lost interrupt hde: lost interrupt hde: lost interrupt .... .... .... .... I get same error continuosly. I tried with LILO too. Is any problem with my Motherboard or RAID card??? Can anyone plz tell me my fault. Any help really appreciated. Thanks in advance.
