Hello,
I am trying to build ramdisk image and launch
bootsplash image at boot time.
Steps I followed:
1. get splash image initrd.splash using splash
binary.
2. dd if=/dev/zero of=initrd bs=1k
count=4096
/sbin/mke2fs -F -m0 -b 1024 initrd
/sbin/tune2fs -c 0 -i 0 initrd
mount -t
ext2 initrd /mnt/user -o loop
3. cd /mnt/user
4. mkdir /boot
5. cp /home/user/initrd.splash /boot
6. umount /mnt/user
7. gzip -v9 initrd
8. results in initrd.gz
Now while compiling kernel image I am
embedding initrd.gz into it. Here is what I am doing
***************System.map**************

_binary__tmp_initrd_gz_start

I am using YAMON bootloader. While booting I
am passing following parameters to kernel:

while booting it still complaining that haven't
found the initrd.splash file. which actually loads splash screen.
Please help where is the problem, Which step I am
doing wrong? |
