I have an AS1200, and wish to be able to boot from network. After

(boot ewa0.0.0.3.1 -flags 1)
Trying MOP boot.
........
Trying BOOTP boot.
Broadcasting BOOTP Request...
..file open failed for bootp/ewa0.0.0.3.1
bootstrap failure
Retrying, type ^C to abort...
(boot ewa0.0.0.3.1 -flags 1)

I tried to search how to implement a server; i concluded i had the
choice between MOP and BOOTP. Since Google is really not verbose at all
about MOP (I only found one daemon, and no documentation about
configuration; the one which has docs only runs on BSD, have not been
ported to Linux), I am gone for BOOTP.
At the moment, I have a working PXE server; and take it as a start. Note
that this server only works for clients having PXE 2.0 cards; cards
using PXE 1.0 do not like it - no clue why. This means, I have a working
DHCP and TFTP servers. DHCP is ISC dhcp3-server; TFTP is tftpd-hpa, all
on Debian x86 testing.
Here is the relevant DHCP section:
| Quote: | host AlphaBeta {
hardware ethernet 00:00:f8:10:48:41;
fixed-address 192.168.0.12;
server-name "fly";
next-server 192.168.0.205;
filename "/home/tftp/alpha/vmlinuz-2.6.18-6-alpha-smp";
}
|
(path are absolute PATH in regard to server, other wise, it does not
work at all for PXE or CLI tftp client)
Here is Alpha response to this:
| Quote: | P00>>>boot -protocols bootp ewa0
(boot ewa0.0.0.3.1 -flags 1)
Trying BOOTP boot.

..file open failed for bootp/ewa0.0.0.3.1

And what server says:
| Quote: | Sep 30 00:03:43 fly dhcpd: BOOTREQUEST from 00:00:f8:10:48:41 via eth0
Sep 30 00:03:43 fly dhcpd: BOOTREPLY for 192.168.0.12 to AlphaBeta (00:00:f8:10:48:41) via eth0
Sep 30 00:03:45 fly dhcpd: BOOTREQUEST from 00:00:f8:10:48:41 via eth0
Sep 30 00:03:45 fly dhcpd: BOOTREPLY for 192.168.0.12 to AlphaBeta (00:00:f8:10:48:41) via eth0

I use an Alpha Linux kernel, because I did not know what to put.
Shall BOOTP answer a bootloader like for PXE, or a kernel file ?
Where/how do I get a bootloader ? For x86, there is a syslinux project;
any equivalent for Alpha ? (maybe not required).
How to pass kernel arguments and initrd informations ?
Are there specific options/features I should set in DHCP conf ?
Am I right in focusing on BOOTP and forget about MOP ?
How/does ISC make the difference between a BOOTP and a PXE request ?
What does the server-name field should point to ? should this name have
public resolution ? when is it solved ?

Just in case, i provide my complete /etc/dhcp3/dhcpd.conf ...

Server is fly(192.168.0.205); client is Beta(192.168.0.12).
