To avoid database corruption, Btrieve uses two methods of updating records : " pre-image paging " in Btrieve versions before 6.0, and " shadow paging " in subsequent versions.

Some of the above hypervisors actually require EPT in order to work at all ( not just faster ) as they do not implement a software shadow page table; the list is not fully updated to reflect that.

However, if a system failure occurred while doing the update to the shadow page the PAT would not be updated and so the change would be dropped because the current and next entry was not updated in the PAT.

When the guest was an operating system that itself implemented virtual memory, even non-privileged instructions could experience longer execution times-a penalty imposed by the requirement to access translation tables not used in native execution ( see shadow page tables ).

This page is called a " shadow page " because it still has not had its location written to the file's PAT . Once the update to the shadow page completed, the PAT was updated and the entry recorded in the PAT of the next available and current physical page in the file.

Modern processors use the concepts of physical memory and virtual memory; running processes use virtual addresses and when an instruction requests access to memory, the processor translates the virtual address to a physical address using a page table or shadow page table ), and once inside the host system ( using hardware page table ).

Also we are 9 days away from Kickstarter launch, that is the date when main stream websites are scheduled to cover the game according to Elysian Shadows page, the developers have revealed they have already conducted interviews with several high profile publications such as EDGE .-- talk ) 09 : 05, 22 July 2014 ( UTC)
