This information is all for a DECstation 5000 Model 200.  In particular,
my ROM version is:  KN02-AA V5.3c  

All stuff here is typed at the console prompt ">>"

1) use 'cnfg' to see what hardware you have installed:

>>cnfg
 7: KN02-AA  DEC      V5.3c    TCF0  ( 96 MB)
 6: PMAD-AA  DEC      V5.3a    TCF0  (enet: 08-00-2b-1b-c1-24)
 5: PMAZ-AA  DEC      V5.3b    TCF0  (SCSI = 7)
 1: PMAD-AA  DEC      V5.3a    TCF0  (enet: 08-00-2b-1a-80-19)

so I've got 2 ethernet interfaces, 1 on the mother board and 1 card.  The
hardware addresses are shown.

slot #6 is the mother board ethernet adapter.  Option slots 0,1,2 are the
3 places you can plug in boards.  #0 is the left hand one looking at the
back of the computer, they are labeled "0" "1" "2".

So 08-00-2b-1b-c1-24 in my on board ethernet and 08-00-2b-1a-80-19 is my
extra card installed in the middle slot.

the default is slot6, the on board interface.  The generic command is:

   boot <slot_number>/tftp

for example to boot from the ethernet interface in slot 1, I'd do:

>>boot 1/tftp

turn on the computer to get a boot prompt.  The envirinmne variable
'haltaction' has some effect on this.  Settings for haltaction are:

b  = causes the system to perform a boot command
h  = causes the system to halt and accept command from the console
r  = causes the system to perform a restart operation or, if that fails to
     perform a a boot operation.

>>printenv boot
 boot=5/rz0/netbsd -a

says my default is to boot from slot 5 (the scsi), disk rz0, boot the
kernel "netbsd" with flags "-a".

to set to always boot from the network card in slot 1, do:

>> setenv boot "1/tftp"

don't know.

don't know.



hope this helps
