38 * DOSVM_Int11Handler (WINEDOS16.117)
40 * Handler for int 11h (get equipment list).
43 * Borrowed from Ralph Brown's interrupt lists:
45 * bits 15-14: number of parallel devices
46 * bit 13: [Conv] Internal modem
48 * bits 11- 9: number of serial devices
50 * bits 7- 6: number of diskette drives minus one
51 * bits 5- 4: Initial video mode:
57 * bit 2: [PS] =1 if pointing device
59 * bit 1: =1 if math co-processor
60 * bit 0: =1 if diskette available for boot
63 * Currently the only of these bits correctly set are:
65 * bits 15-14 } Added by William Owen Smith,
66 * bits 11-9 } wos@dcs.warwick.ac.uk
68 * bit 2 (always set) ( bit 2 = 4 )
69 * bit 1 } Robert 'Admiral' Coeyman
