Hi folks,
I'm posting here to check if the code in 
http://www.virtualbox.org/browser/trunk/src/VBox/Devices/PC/DevPcBios.cppVBoxMan
age is live and all the settings in 
 /**
889     * @interface_method_impl{PDMDEVREG,pfnConstruct}
890     */
891    static DECLCALLBACK(int)  pcbiosConstruct(PPDMDEVINS pDevIns, int 
iInstance, PCFGMNODE pCfg)
892    {
are visible in the PEUL version?

A more detailed overview (logs, xml, etc) of what I have tried is in 
post on community forums

I am trying to use  

setextradata "pxe2" "VBoxInternal/Devices/pcbios/0/Config/DmiChassisAssetTag" "l
oantag"

from a windows XP host to a windows PE ( 6.1.7600 ) guest.


I am having difficult querying it on a WinPE guest, the value appears to be 
accepted into the pxe2.xml and valid in the log but I am getting No Instance(s) 
when I query it within the WinPE.
Other queries work.

C:\wmictests>wmic csproduct list brief
Caption IdentifyingNumber Name Vendor Version
real:Computer System Product R8PVHR0 7459VTT LENOVO ThinkPad X200
vm: Computer System Product 0 VirtulaBox innotek GmbH 1.2

C:\wmictests>wmic systemenclosure get smbiosassettag
SMBIOSAssetTag
Real: loankit
V: No Instance(s) Available.
(No systemenclosure values exist)

I've looked at the source code (possibly not for this version). 
http://www.virtualbox.org/browser/trunk/src/VBox/Devices/PC/DevPcBios.cpp
and the value (ChassisAssettag) I'm interested in seems to be exposed.

I have read interesting diversions about BIOS addins in 
http://vbox.innotek.de/pipermail/vbox-dev/2008-May/000606.html

I appreciate that this is in a grey area as far as a post on a dev list, but a 
reply with a list of what setextradata values are available to set and read 
would be great. A pointer to the relevent code would be useful though I am 
unlikely at this point to do any development coding.
