Unable to access bios thru del or Fxx touch

Hi
Long story
I got my hands on decomissioned transaction recording modules called MEV in french
They are working but they have been Kinda resetted, id tags removed, meaning no restorant softwares on them, they boot on 4gb CF cards with windows XP embedded.
They are AAEON aec-6822 pdf link: http://data-us.aaeon.com/DOWNLOAD/2007% ... C-6822.pdf
Asked some infos at AAEON, no responses for an original bios.
EDIT : it's an AAEON gene-9455 rev B board in them
First thing i did was to hack/add an admin user and password, since i dont know them ...
Now i have a full windows access ... made some raw backup before playing in them just in case.
Now the fun part
The bios can't be accessed by any mean IE: DEL keypress or any F1 thru F12 key at bootup ?? even disconnected the coin cell 2 days, nothing was resetted / changed.
I'm able to backup / read the bios I can post it on an file hosting
I want to do some bios changes / boot order and i can't do that.
If i swap the CF card between 2 MEV'S they will boot but a constant beep wil be heard, i think there is an signature check somewhere, maybe an dll check, a bios check ... combination ??
On an old install log, i see an given id to the computer.
I know softwares like modbin, cbrom etc ... flash tools etc ...
Is it possible to add the DEL functionality back ??
thks
