Log:
[NTVDM]
Start my work on modularizing registration of "32-bit" interrupts, i.e.
interrupts that are implemented in 32-bit mode, but are stubbed with 16-bit
code (so that 16-bit apps can call them).
The 16-bit stub code uses a BOP call to our Control BOP function (BOP 0xFF) which
can handle in theory many sub-functions (as the BOP 0x58 documented here:
http://www.ragestorm.net/tutorial?id=27)
specified as an additional BYTE in the call:
0xC4 0xC4 bop_code <optional_bop_subfunction>
Here, for calling 32-bit interrupts we use our BOP 0xFF, subfunction 0xFF.
The final aim would be to generate the 16-bit stub code when one calls the RegisterInt32
helper function
(contrary to what's happening now, that is, the 16-bit stub code is generated for all
of the interrupts
at BIOS initialization time, and we use it for BIOS and DOS interrupts).
