1)Downloaded(sourceforge.net) & compiled the U-boot 1.1.6 files to get
u-boot, u-boot.srec & u-boot.bin (I didn't find ml403 board config for the
uboot. So used ml300_config).

U-boot 1.1.6 is ancient.  The u-boot project has moved off of
sourceforge to denx.de

After this, I tried to convert the u-boot (README says that this is an ELF
file) into an ace file. But, it gave me the error saying unable to read elf
file. Is it because ML403 board is not supported or is it possible that the
u-boot image that I created is corrupted?

I don't know; but personally I don't weld u-boot into an ace file. I
use a 1st stage bootloader to load the u-boot image off the cf card
(but unfortunately I'm not able to post that loader at this time).
Try again with a recent u-boot version.

2) Since generating ace files failed, I tried to search the net for an
u-boot ace file that could run on ML403 & found it at
http://88.191.24.164/docenligne/projets/samba/2006/linux-embarque-sur-ml-403/u-boot-ml403.ace/view

I copied this ace file (u-boot-ml403.ace) along with the kernel 2.6 image
(uImage) onto my CF card & booted the board. After loading the kernel, it
fails to read the correct root device. I tried changing the "bootargs" env
variable root = /dev/xsysace/disc0/part2 rw to root = /dev/xsysace2 rw &
root = /dev/xsda2 rw.

But, it failed in both cases. (There was a previous post on Problem2 a year
ago & he solved it by giving root =/dev/xsysace2)

Looking at your bootlog, it doesn't look like you've got the systemace
driver built into the kernel.

Cheers,
