Sun ND server?

Is there an implementation of Sun nd(4) (Network Disk) server other than the one in NetBSD, by Matt Fredette? Long story: Few days ago I fried SCSI controller on Indigo 2, and I'm not gonna risk the same with my Sun 3/60. Few months ago I got SunOS 3.5 kernel to netboot using modified NetBSD ndbootd(8); it goes as far as mounting rootfs. Then, just after printing the following line... using 95 buffers containing 778240 bytes of main memory ... it just retries reading block number 16 over and over. I guess the ND protocol implementation is wrong somehow. The whole transaction goes like this; the only thing that changes is the "seq" field.
