Help request for booting from hardisk using PPCBUG

Someone has installed a bootable Perp boot partition on a SCSI machine
I must send back to motorola. Now that I have a working debian linux
installed,  I would like to put the image on teh IDE disk instaed of
booting it using NBO.

Here is what I already have done : 

     1) create a 0x41 bootable partition on the IDE DISK
     2) copied zImage in this partition using dd
     
It did not work. I the have remove the first 512 byte of netboot
zImage and replaced it by 512 byte of IDE1 master boot block to
get a correct partitions info but it did not change anything.

I'm wondering if there is any trick??? One I though of is the
LBA geometry versus physical geometry used so far. Any opinion?

Heads: 9   Sectors per Track: 63   Cylinders: 14848

I have a C/H/S of 14848/9/63. The BIOS LBA setting for this disk
is probably different...
