[SunHELP] Ultra 24 BIOS / Gbe configuration

[sawbona at gmx.net]

Hello:

I have an Ultra 24 Workstation running under Devuan ASCII.

Even though the BIOS has no user or system passwords set I cannot access the on-board 
Gbe settings, as they are greyed out. ie: blocked  

This means that I cannot disable WoL or change the power management settings for the 
on-board Intel 82566DM-2 Gbe controller in the BIOS.  

I need to be able to change these settings to see if I can solve a shutdown problem that 
seems to be related to WoL and EEE.

I cannot understand the reason behind the Gbe settings being blocked from administrator 
control nor have I seen this in any other machine I have had, but if the Ultra 24 BIOS (v. 1.56) 
reports the system as being a "portable device", I guess I can expect almost anything.

~$ inxi -b
System: Host: devuan Kernel: 4.9.0-8-amd64 x86_64 (64 bit)
Desktop: Xfce 4.12.3
Distro: Devuan GNU/Linux ascii
Machine: Device: portable   <------------ !!! 
System: Sun Microsystems product: Ultra 24 v: 0.00.01
Mobo: Sun Microsystems model: Ultra 24 v: 50

CPU: Quad core Intel Core2 Quad Q9550

Q: does anyone on the list have any idea as to how to unblock Gbe access in BIOS?

Thanks in advance.
