The 'Time out waiting for ARP/RARP packet' is normal, if there was no RARP deamon responding, there would be much more RARP Time-out messages. But the '4200 Data Access Error' is a scary one ... 4000 is the default download start address. 4200 is start plus 200. 0x200 is 512 decimal, the size of a default TFTP packet. How to classify 'Data Access Error' is the challenge. If there are problems with memory, the 'ok' wouldn't probably not been show. Just do a simple check by these five separate command at the 'ok' prompt: 40000 400 dump 40000 400 55 fill 40000 400 dump 40000 400 AA fill 40000 400 dump to make sure it is really no memory problem. I see one possible cause of the probleem: Size of the TFTP packet. I imagine that the first TFTP block is transferred fine and the next block goes wrong, due allocated size and actual size differences. The wireshark analyzis could reveal it ... [1] Over here I do succesfull netboots on an Ultra 5, it has OpenBoot 3.19. As tftp server is also tftpd-hpa used, under inetd. But shouldn't make a difference. Difference is that I don't do '-r blocksize' Cheers Geert Stappers DD [1] I'm willing to check a wireshark slash tcpdump .pcap file that is all ready filtered to contain only packets that match the MAC address of the E250. You may send that binary file off-list to me. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
