 I am sorry to post the same message repeatedly, because of MIME format.
 I am using u-boot-0.4.0 + linux-2.4.18-rmk7-swl8 + self-made ramdisk on smdk2410(s3c2410
cpu) board.
 Kernel is being successfully uncompressed and booted, but ramdisk isn't mounted.
 My ramdisk is tested well on the same board and kernel without u-boot.
 Ramdisk seems not to be loaded before uncompressing the kernel.
 The address where the kernel is being performed is 0x30f00000 and ramdisk's is at
 System logs are as follows.
Thank you in advance.
