... or your BIOS version is different and the OEM BIOS strings have moved
in this case we would need to enlarge the BIOS address space being groped
i.e. expand the { 0xf0000, 0xf1000 } range in struct bios_oem bios_soekris
In any case, on a net4801 you should see in the dmesg:
Geode Soekris net4801 comBIOS ver. 1.27a 20041206 Copyright (C) 2000-2004
otherwise all bets are off with regard to /dev/led/error!
Here are my stats:
On net4801
comBIOS ver. 1.27a 20041206 Copyright (C) 2000-2004 Soekris Engineering.
FreeBSD 6.2-STYX-20070430 #0: Tue May 1 05:39:26 UTC 2007
as well as
FreeBSD 6.1-STYX-20060705 (STYXMFS) #0: Thu Jul 6 09:36:19 UTC 2006
(these are custom kernels builds based on FreeBSD on those dates)
both kernels report from sys/i386/i386/geode.c:
Geode GPIO@ = 6100
Geode Soekris net4801 comBIOS ver. 1.27a 20041206 Copyright (C) 2000-2004
and the led/error device is created:
$ ls -l /dev/led/error
crw------- 1 root wheel 0, 32 Sep 3 09:39 /dev/led/error
and
# echo d12 >/dev/led/error
flashes the red LED.
I have in the kernel config:
cpu I486_CPU
cpu I586_CPU
options CPU_SOEKRIS
options CPU_GEODE
options CPU_ELAN
(CPU_ELAN is in there so that the 4501 is supported as well).
On net4501:
comBIOS ver. 1.22 20031029 Copyright (C) 2000-2003 Soekris Engineering.
FreeBSD 6.1-STYX-20060705 #0: Thu Jul 6 09:31:22 UTC 2006
as well as
FreeBSD 6.2-STYX-20070430 #0: Tue May 1 05:39:26 UTC 2007
reports from sys/i386/i386/elan-mmcr.c:
Elan-mmcr driver: MMCR at 0xc5b68000.
Elan-mmcr Soekris net45xx comBIOS ver. 1.22 20031029 Copyright (C) 2000-2003
and /dev/led/error works as expected
Hope this helps!
