Buffer memory NVRAM
The motherboard is equipped with an NVRAM that applications can use to back up data in
the event of a power failure. Failure of the supply voltage for a duration longer than 5 ms is
indicated by the DC FAIL signal.
At least enough time is provided for copying data to the NVRAM so that 128 kB can be
backed up with the full configuration.
A memory window with a maximum size of 512 KB can be displayed by means of PCI
address register. The base address is initialized via the BIOS (see section "Input/output
address areas (Page 116)").
A corresponding function is implemented there for using the NVRAM under WinAC RTX.
