Great, that's really awesome work! Much obliged.

Thanks for providing a ready-to-use ECOFF kernel. I just now gave it a 
try on my Indigo R3K. It starts good but later it isn't able to get the 
needed BOOTP/DHCP info. Not sure why, but the MAC address of the sq0 
device is all 0 (00:00:00:00:00:00) as soon as the kernel starts. The 
MAC address looks OK in the PROM monitor though and netbooting actually 
works as expected from there:

```
>> eaddr

Ethernet address is ---- 08:00:69:11:22:33

I noticed, that the kernel you used when producing your log further 
below is actually revision 8.99.21 and was built at an earlier date 
than the one from GitHub. Another difference is that my log is missing 
the "wdsc0: microcode revision 0x0c, Fast SCSI" line.

So could it be that there is a small difference between both kernel 
revisions that somehow breaks the MAC address?

Here is my full log for reference:

UPDATE: Configuring 00:00:00:00:00:00 for my Indigo R3K in `/etc/ethers` 
for rarpd actually allows it to continue the netboot process, but still

Hey, but this is much closer to useful than ever before. Thanks for
