AOA 110 cant startup after resotre defaults

I have a deskless AOA 110.

I had problems whit the linpus distribution.
Default gui failed and sudenly i had xfce.

I created a bootable usb whit UBUNTU 10-10 Netbookedition. and installed it
It runs but slowly.
To speed it up i Installed a Kingston Value 1GB PC2-5300 RAM Chip hopeing to speed it up .

System worked as before but the Startup F2 shows 512 Mbit memory. not 1536 as expected.

Memory size could not be changed by F5/F6 so i did a mistake...

Restore Defaults!!! F10 save and exit

Now nothing ... it just wont boot anny more

How do i boot it up again and what settings is needed to start preferably whit 1.5 Gb ram

Solved boot problem by downloading bios 3309 and create a flash-usb.
hold down fn+esc while power on. release when power flashing. push power once.

15 sek later it booted up in UBUNTU 10-10 but still only 512 Mbytes RAM.

Any ideas on how to activate the extra 1 Gb installed ?
