Mike,

Once I had problems with FBSD6.0's standard tftp server 
(/usr/libexec/tftpd) ignoring the blksize option as specified by clients.

The symptoms were similar: transfers 'completed', but 
no/partial/unusable file.

<inetd.conf>

#tftp	dgram	udp	wait	root	/usr/libexec/tftpd	tftpd -l -s /tftpboot
#standard tftp server ignores client's blksize request (of 1432) and 
sends 512 byte blocks regardless

#installed tftp-hpa-0.41 instead from port
tftp	dgram	udp	wait	root	/usr/local/libexec/in.tftpd	in.tftpd -a 
10.1.2.1:69 -T 500000 -t 15 -v -s /usr/jail/usr/minibsd/boot

</inetd.conf>

HTH

Best wishes,
Steve
