Use Int 13 first ala:

'$INCLUDE: 'qb.bi'         'Dick Dennison 1:272/34
'Check for floppy drive door open
DIM regs AS RegType        '3/93 Public Domain
regs.ax = &H201            'Int 13 Ser 2  Read sector
         'ah=2 al=1(sector to read)
regs.dx = 1                '0=a:, 1=b:
INTERRUPT &H13, regs, regs 'Call int 13
PRINT regs.flags AND 1     'If carry flag is set then
         'there was an error (probably no disk)
PRINT HEX$(regs.ax AND 255) 'error code is in AL
