Supported DPMI INT 31h functions

PMODE/W duplicates a subset of DPMI protected mode functions. These functions are available ONLY in protected through INT 31h. They provide descriptor services, extended memory services, interrupt services, translation services, and some other miscellaneous things. A function is called by setting AX to the function code, setting any other registers for the function, and executing INT 31h. Upon return, the carry flag will be clear if the function was successful. If the carry flag is set, the function failed. All other registers are preserved unless otherwise specified. In addition to the functions listed here, functions 0600h, 0601h, 0702h, and 0703h will return with the carry flag clear to stay compatible with code that uses those particular DPMI functions.
