Borland C++ 2.0 DPMILOAD.EXE - ALLOCATE MEMORY

AX = FB42h
BX = 0002h
CX = size in bytes
DX = bit flags
bit 2:
Set to allocate DOS memory, clear for DPMI memory.
SI = selector of descriptor to be modified to access allocated memory.
DI = selector of a second descriptor to be modified

Return:
AX = ??? or 0000h on error
CX:DX = linear base address of DPMI memory block
SI:DI = handle for DPMI memory block or FFFFh:FFFFh
???

Note: Two segment descriptors may be set if a code and an aliased data segment are required; if only one descriptor is needed, SI should equal DI on entry

BUG: When allocating DOS memory, the code computes the linear address by multiplying the segment number by 4 rather than shifting by 4
