Rom01 GS refuses to netboot

[Steven Hirsch <snhirsch@gmail.com>]

This is an odd one.  My netatalk server is setup for network boot of both IIe 
and IIgs clients.  The IIe works great, as does my Rom03 gs.  The Rom01, 
however, absolutely will not netboot.  It doesn't even try, according to 
wireshark.  At startup the machine pauses at the splash screen, then boinks 
and shows Check Startup Device.  If I boot the box with a network-enabled 
GS/OS diskette, everything is fine and I can sign on as a client.

I've tried with my trusty Gatorbox and the EtherPrint LT - no dice either way.

Settings are (and remember, this works fine for the client diskette):

Slot 1 : Your Card
Slot 2-6 : Internal
Slot 7 : AppleTalk

Boot: Scan (I've also tried 1 and 7)

The only other storage device is an Appledisk 3.5 on the built-in smartport.

I've tried resetting the CMOS to 60Hz + Standards and reconfiguring from 
there.  No luck.

Others tell me they have no problem netbooting a Rom01.  Anyone have a theory 
why this won't cooperate?
