Hello: After Installing RHEL3 on a system that has one SATA HDD, from a borrowed IDE CD-ROM, I could boot fine. As soon as I remove the CD-ROM drive, I can't boot the system anymore. When I reconnect the CD-ROM again, all is well. I have looked at the boot.log, messages, and dmesg to get an accurate account of the problem, but I can't recognize anything that points to the problem. I think when the CD-ROM is removed, the system looks at the wrong (device, partition) to boot from - should look for "sda", but looks for "hda" instead ? I am using an Intel 865G motherboard - when I reboot, I get a message from Kudzu regarding the Ide Interface Controller: "Intel |82801EB Ultra ATA Stroage Controller has been removed". I have tried "remove", "configure", "igore". no difference. This controller, allows for PATA/SATA devices to co-exist. Does that confuse Linux? Things I have tried: I have configured BIOS, where the IDE assignments can be selected: When On-Chip IDE Devices setting is set to "AUTO", boots up ok, but when the CD-ROM is disconnected, boot fails. When On-Chip IDE Devices setting is set to "SATA Only", w or w/o CD-ROM connected, boot fails. The grub.conf is as follows. (I have tried passing some kernel variables as suggested in online forums, none has helped): Title Red Hat Enterprise Linux WS (2.4.21-4.EL) Root (hd0,0) Kernel /vmlinuz-2.4.21-4.EL ro root=LABEL=/ Initrd /initrd-2.4.21-4.EL.img Here is the bottom portion of the boot messages: Loading libata.o module Loading ata_piix.o module PCI: Found IRQ 11 ofr device 00:1f.2 Ata: 0x11f0 IDE port busy Ata1: SATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0xF008 irq 15 ATA: abnormal status 0x7F on port 0x177 ATA: abnormal status 0x7F on port 0x177 Ata1: thread exiting Scsi0: ata_piix Starting timer: 0 0 Loading jbd.o module Journalled Block Device driver loaded Loading ext3.o Mounting /proc filesystem Creating block devices Creating root device Mounting root filesystem Mount: error 6 mounting ext3 pivotroot: pivot_root(/sysroot, /sysroot/initrd) failed: 2 umount /initrd/proc failed: 2 Freeing unused kernel memory: 164k freed Kernel panic: No init found.
