Desc: Redirected to INT 02 by the BIOS, for compatibility with the PC
Notes: May be masked by setting bit 5 on I/O port A1h. Not all clones wire the coprocessor to generate this IRQ; some systems generate an NMI (see INT 02) or assert the -ERROR pin on the CPU (see INT 10"COPROCESSOR"). Under DESQview, only the INT 15h vector and BASIC segment address (the word at 0000h:0510h) may be assumed to be valid for the handler's process
