Hi

Having just gone back to my Jensen ROM rev 1.4 I've noticed
that a BOOT EZ0 only works *after* the system has at least once
done a netbsd boot from disk. 

So without any previous disk boot I get (reproducible):

>>> b ez0
INIT-S-CPU...
AUDIT_BOOT_STARTS ... 
AUDIT_BOOT_REQ 
AUDIT_BSERVER_FOUND IP 192.168.200.1
AUDIT_BSERVER_FOUND ENET 00-00-F8-20-7F-45
AUDIT_LOAD_BEGINS

AUDIT_LOAD_DONE


?05 HLT INSTR
  PC= 00000000.20021F90 PSL= 00000000.00001F00

>>>

With a disk boot in between I get:

NIT-S-CPU...
AUDIT_BOOT_STARTS ... 
AUDIT_BOOT_REQ 
AUDIT_BSERVER_FOUND IP 192.168.200.1
AUDIT_BSERVER_FOUND ENET 00-00-F8-20-7F-45
AUDIT_LOAD_BEGINS

AUDIT_LOAD_DONE

It sort of appears that some part of memory is not initialised before use
or so??

Please note that this is all based on 1.2 bootblocks, maybe I should get the
1.3 bootblocks, assuming they'll coexist with 1.2 for the rest of the
system. Are they around somewhere in a managable chunk (28K8 modem is
not very suitable to download a complete snapshot)
