As you wrote, everything works until the kernel is about to mount the root filesystem, very good for a first attempt! :) The exact error is that the initrd is unable to load the driver for your IDE controller, errno=2 means File not found, and hence the kernel can not find hda2. > I used a command like this to make the elf image. > > mkelfImage --command-line="root=/dev/hda2 rw console=ttyS0,115200n8" \ > --kernel=/boot/vmlinuz-2.4.20-8smp --ramdisk=/boot/initrd-2.4.20-8smp.img \ > --output=/root/elf/linuxImage > > I think my root parameter at the mkelfimag command is correct > because I type mount command on the console when I have the AMI > BIOS booting the linux from the HardDisk, it looks like this, > > [EMAIL PROTECTED] bin]# mount > /dev/hda2 on / type ext3 (rw) > none on /proc type proc (rw) > usbdevfs on /proc/bus/usb type usbdevfs (rw) > /dev/hda1 on /boot type ext3 (rw) > > If anybody tell me what I did wrong, I would be really appreciated. I suggest you try making an ELF image without an initrd and if neccessary compile a kernel with drivers for your hardware compiled in statically. This shouldn't be too difficult.

Indeed, this is another option. But a new kernel is still neccessary since the one in the ELF image (/boot/initrd-2.4.20-8smp.img) came with neither ext3 nor IDE drivers. //Peter _______________________________________________ Linuxbios mailing list Linuxbios@clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios
