Another OpenBSD on WRAP user wrote to me saying that pxeboot works.
Also, I found http://www.ultradesic.com/?section=43 which descripbes
PXE booting OpenBSD for the Soekris plattform which is very similar to
WRAP.
Both encouraged me to dig deeper:
a) pxeboot finds both labels '!PXE' and 'PXENV' in the BIOS code;
b) the checksums of both those BIOS section are OK, e.g. PXE code in
the BIOS appears to be intact;
c) forcing pxeboot to use the legacy PXENV (instead of the !PXE v2.1)
API results in pxe_call() to return OK. (forced by commenting out the
line " bang = 1; " in /sys/arch/i386/stand/libsa/pxe.c)
However, it appears that result fields of those calls are filled with
zero. Because calls of pxeinfo() returns with IP addresses and netmask
as 0.0.0.0, instead of DHCP client & server addresses.
d) Upgrading WRAP's BIOS from 1.08 to 1.10 did not make any difference.
Notably finding c) encouraged me to also question my DHCP server
configuration, which currently is:
host wrap {
hardware ethernet 00:0d:b9:01:a0:a4;
option host-name "wrapobsd";
fixed-address 10.0.0.20;
next-server 10.0.0.3;
option root-path "10.0.0.3:/tftpboot";
filename "/pxeboot";
}
Just to crosscheck the PXE capability of WRAP's BIOS, I also tried to
load pxegrub from GRUB as 2nd stage boot loader, instead of pxeboot
from OpenBSD. So far, pxegrub gets loaded, but I do not get any GRUB
prompt yet (something with serial console port parameters might still
be wron in my GRUB configure).
Any suggestions warmly welcome,
Rolf
