bootp on IRIX server

I am attempting to install Linux on an Indy but I am running into a problem
the instructions are for using bootp on a i386 host, I am interpreting the instructions
for an SGI host .
here is what I have: /etc/inetd.conf bootp   dgram   udp     wait    root    /usr/etc/bootp bootp -f /etc/bootptab
tftp    dgram   udp     wait    root    /usr/etc/tftpd  tftpd -s  /usr/src/sgi/installfs
bootparam/1 dgram   rpc/udp wait    root    /usr/etc/rpc.bootparamd bootparamd

/etc/bootptab: (server info)
/usr/src/sgi/installfs
vmlinux
(client info)
cygnus                  1 08:00:69:09:2d:9b     169.238.59.4    vmlinux

  I have successfully connected with the server -- the kernel boots - but the kernel cannot
mount the network file system. I get RPC errors pointing to nfs and mountd :
Looking up port of RPC 100003/2 on 169.238.59.23
RPC: sendmsg returned error 128
portmap server 169.238.59.23 not responding , timed out Looking up port of RPC 100005/1 on 169.238.59.23
RPC: sendmsg returned error 128
portmap server 169.238.59.23 not responding , timed out

Root-NFS: Unable to get mountd port number from serve, using default rpcinf -p output is :

I know I have permissions problems but I'm not sure where. oh by the way
/etc/exports:
/usr/src/sgi/installfs -anon=root,nohide,root=cygnus
  any information you can give will be most appreciated. Thanks Al
