INT 7F - Alloy NTNX - GET SYSTEM FLAGS AH = 0Ah CL = 00h ES:DI -> buffer for system flags (see #03949) Return: ES:DI buffer filled Notes: on a slave, only the NX_Busy flag is returned all three flags are at fixed positions, so this function only needs to be called once an interrupt handler should only perform DOS or device accesses when all three flags are 00h Format of Alloy system flags: Offset Size Description (Table 03949) 00h DWORDDoubleword; four bytes. Commonly used to hold a 32-bit segment:offset or selector:offset address. pointer to NX_Busy flag (nonzero when communicating with users) 04h DWORDDoubleword; four bytes. Commonly used to hold a 32-bit segment:offset or selector:offset address. pointer to device driver busy flag 08h DWORDDoubleword; four bytes. Commonly used to hold a 32-bit segment:offset or selector:offset address. pointer to InTimer flag
