I am trying to create a custom boot disk for a PXE style network boot. I can take an image of a rescue boot floppy (1.44MB or 2.88MB) and place this on the PXE server and the PXE client will boot the image, so I know the server is working...
I am using the following procedure to create the boot disk image; - create a loopback device to build my root file system in dd if=/dev/zero of=myroot bs=1k count=4096 mke2fs =m 0 -N 2000 myroot mount -o loop myroot /mnt - create the /dev, /proc, /etc, /sbin, /bin, /lib, /usr, /var directories - create the /dev files - populate the /etc, /sbin, /bin, /lib directories... ldconfig -r /mnt umount /mnt dd if=myroot bs=1k | gzip -v9 > myrootfs.gz - build a kernel (v2.4.20) with ext2 and ramdisk support (8MB), and other support needed make menuconfig make dep; make bzImage; - merge the two steps dd if=bzImage of=mybootdisk bs=1k 788+1 records in 788+1 records out rdev mybootdisk /dev/ram0 (the destination for the root file system when booted) rdev -R mybootdisk 0 rdev -r mybootdisk 17173 (kernel offset + bit 14 set) dd if=myrootfs.gz of=mybootdisk bs=1k seek=789 When this image is booted a Kernel panic is produced: VFS: Unable to mount root fs on 01:00 I think that should be the first RAM disk... On the frozen boot screen, at the top is the message: RAMDISK driver initialized: 16 RAM disk of 8192K size 1024 blocksize -- Can anyone tell me what I have done wrong here? I've rebuilt the kernel many times to make sure I have everything included, but always come back to this error.
