Help booting MBX through bootd

I am trying to use a Motorola MBX860 board in an embedded project.

I download the root.min.tgz system to testing, and I put this
configuration in the MBX:


Controller LUN =00? 20
Device LUN     =00? 
Node Control Memory Address =003C8000? 
Client IP Address      = 
Server IP Address      = 
Subnet IP Address Mask = 
Broadcast IP Address   = 
Gateway IP Address     = 
Boot File Name ("NULL" for None)     =/ppc/zImage? 
Argument File Name ("NULL" for None) =? 
Boot File Length               =00000000? 
Boot File Byte Offset          =00000000? 
BOOTP/RARP Request Retry       =00? 
TFTP/ARP Request Retry         =00? 
Trace Character Buffer Address =00000000? 
BOOTP/RARP Request Control: Always/When-Needed (A/W)=W? 
BOOTP/RARP Reply Update Control: Yes/No (Y/N)       =Y? 

Update Non-Volatile Memory (Y/N)? Y
Updating Non-Volatile Memory - Standby...


I am using an SCO machine for boot...

I make a /ppc directory and ungzip-untar the file inside.

I configure inetd for bootpd and tftp, and nfs to export the /ppc directory,

When i run the download command from the MBX I get this response:

Can anyone help me?
