which it loads several files that replace the corrupted BIOS on the Flash ROM with an
uncorrupted one.
1.19.5 New Interrupt 15h extensions
The BIOS must support the recently defined standard INT 15 extensions.
Big Memory
Big memory support can report greater than 64 megabytes of RAM. The notebook supports
the INT 15h big-memory reporting functions of E801h, E881h, and E820h. This feature
reports all available extended memory (both below and above the 64MB limit) using both a
real mode (E801h) and a 32-bit protected mode (E881h) interface.
Operating systems can access the real-mode interface through the standard INT 15h call.
They can access the protected-mode interface through a 32-bit interrupt call, much like the
EISA protected-mode interface. The Microsoft-defined E820h function returns a complete
memory map through a series of repeated calls.
1.19.6 Plug-n-Play (PnP) Support
To achieve the goal of PnP, POST conflict detection and resolution (CDR) module, and a
run-time services module will be integrated into the system BIOS.
The PnP runtime service module includes multiple interfaces so that the system can support
the current DOS, as well as Win98 operating system that includes specific support for the
PnP BIOS specification.
