Hello Ameet/Ming,

  First of all really appreciate your inputs on this... 
  Problem 1 :
  I was using the factory shipped compact flash as is which comes with a DOS FAT16 partition and a linux 83 partition with ext3 filesystem. I tried it on 2 factory shipped CFs and its the same behavior - . When i plug-in the CF card reader to the linux box it always reads it as "sda" and in the linux2.6.17.1/Documentation/devices.txt - sda is the device file for SCSI disk devices. Wonerding how you guys configured the root option as "/dev/xsa".

  Now i re-formatted my CF, created a ext2 filesystem using busybox-1.1.0 like the BYU instructions. Created 2 partitions on CF card 1. FAT16 partition & 2. linux partition and then created 1. dos file system using mkdosfs and 2. linux ext2 filesystem using mke2fs.

  But the problem still persists and i get "Please append a correct "root=" boot option :"
  :(

  Problem 2: After i included the TEMAC driver and sysace drivers, the kernel just hangs. I thought i'll fix problem 1 before i get to problem 2... 

  With your help i am getting the confidence that i can make this all work!
  thanks once again.

  Hello Ameet,
I am using that driver very well now. There is only one problem. It seems 
that the driver for TEMAC only support Gigabit Enet, not 10/100/1000M 
adapted. But because I want to use the Gigabit enet, I don't care that. So 
it's OK, at lease for 1Gbit/s.

So I don't think Pradeep's problem is caused by Temac. I still suspect that 
he didn't pass a right parameter to "root=", just like what I posted 
before.

Regards
Ming
