Hi there -

I've got a DEC Alpha AS1200 that I'm trying to netboot off another
AS1200.  I'm running into some problems, I've read the netboot document
many times on the site, but I think I might be running into 
a problem that may not have been addressed.

firstly, let me state my goal.  I want to be able to boot an AS1200 with 
the basic install kernel for disaster recovery, et cetera.

Here is the scenario:  bjork wants to boot off of otaku.  Here is what

otaku's /etc/bootptab:


(note, I'm using hd instead of rp, hd is where my netbsd.gz file is)

what /tftpboot looks like on otaku:

drwxr-xr-x  2 root  wheel      512 Mar 13 02:56 mop
-r--r--r--  1 root  wheel    61392 Mar 11 21:49 netboot
-rw-r--r--  1 root  wheel  2538549 Aug 18  2001 netbsd.gz
lrwxr-xr-x  1 root  wheel        1 Mar 14 06:33 tftpboot -> .

bjork's boot command:

P00>>>boot ewa0 -p bootp -fi netbsd.gz
(boot ewa0. -file netbsd.gz -flags -a)

Trying BOOTP boot.

Broadcasting BOOTP Request...
..file open failed for bootp/ewa0.

otaku's server log:

# bootpd -s -d9
bootpd: info(6):   bootptab mtime: Fri Mar 15 01:45:45 2002
bootpd: info(6):   reading "/etc/bootptab"

bootpd: info(6):   arp -d; arp -s 08:00:2B:C3:C5:32 temp

and thats it .. no log message concerning a tftp transfer, yet tftp 
appears to work just fine when bjork is running from a local disk:

bjork$ tftp otaku
tftp> get netboot
Received 61801 bytes in 0.2 seconds
tftp> get netbsd.gz
Received 2554599 bytes in 4.0 seconds

If I change the name of the file or path (bf) in the bootptab, I do
get an error saying that the file couldn't be found.

So, I gave dhcpd a shot .. and I had basically the same results ..

netboot has a few strings in it:


So, I sort of assumed that mopd might be able to be used to grab 'netboot',
so I tried it:


P00>>>boot ewa0 -p mop -fi netboot
(boot ewa0. -file netboot -flags -a)
Trying MOP boot.

Network load complete.

MOP DL 802.3 0:60:97:d1:61:b1  > 8:0:2b:c3:c5:32   len   14 code 02 MLD

So I suppose thats not possible (maybe there is a boot.mop for the 
alpha as there is for the VAX?).

I'm sorry if this topic has been exhausted, but doing a quick search 
on the archive I couldn't find anything specific to the AS1200.  Thank you.
