@pkubaj consider adding some earlyprint over COM. I have no idea if the booting is proceeding or not when I run that menu option.

Do you mean the option in PXELINUX or the autoboot option in iPXE? Generally, both load very quickly and it's usually you environment (dhcpd or tftpd configuration) which is bad.

@pkubaj what if I do not have a DHCP server running?

With this procedure, it won't work. I'll prepare another one, for when there's no DHCP.

Please verify now.

miczyg1 · 2017-08-31T07:19:34Z

I could not reproduce the procedure to boot BSD installation. Possible reason is that I have no DHCP server running. @pkubaj think about some workaround so I could try it too.

pkubaj

Changed version to 6.1 and whitespace fix. Another procedure for use without DHCP will be prepared later.

Add info about SHA256, signatures and booting without DHCP.

-  Note that it has to be in  tftpd root directory, not the directory where bsd
-  files are!
-
+  You need to adjust IP's and netmask to your own environment.
 3. Boot configuration.


@pkubaj add a new line before "3. Boot configuration" because it appends to the previous line.

miczyg1 · 2017-09-01T10:31:04Z

I still could not reproduce it. Steps I did:

Download pxeboot and bsd.rd
Copy to netboot directory and rename to pxeboot.0 and bsd
Reate symlink auto_install to pxeboot.0
Add entry in the menu:
label open-bsd
menu label ^OpenBSD-6.1
menu default
kernel pxeboot.0
Create install.conf and put in netboot directory
Power up apu2 board and enter ipxe shell
Type commands:
dhcp net0 --- (because I have added static IP address to aup2c MAC)
set filename pxelinux.0
set next-server 192.168.0.109 --- (docker host ip)
chain tftp://${next-server}/${filename}
8 Choose OpenBSD-6.1 option

Note: changing filename to pxeboot.0 or auto_install results in reboot after ~15 seconds.
Providing pxelinux.0 as filename allows me to get PXE menu. Choosing option OpenBSD-6.1
either with kernel pxeboot.0 or kernel auto_install causes reboot of the APU board.

pkubaj · 2017-09-01T17:45:05Z

To simplify things, I set up to only boot OpenBSD directly from dhcpd. Here's my environment:
dhcpd.conf

default-lease-time 604800;
option ntp-servers 192.168.0.1;
option domain-name-servers 192.168.0.1;
subnet 192.168.0.0 netmask 255.255.255.0 {
        option routers 192.168.0.1;
        range 192.168.0.4 192.168.0.254;
	filename "auto_install";
}

pxeboot is this file:

bsd is this file:
https://mirror.leaseweb.com/pub/OpenBSD/6.1/amd64/bsd.rd
This should be all you need to boot via PXE.

Some corrections, putting auto_install to dhcpd.conf gives me:

Failed to load ldlinux.c32

Unfortunately, this introduces another Enter that user needs to press.
