INT 15h, Function AX = 5380h, Subfunction BH = 0Fh: Read Ethernet/System
ID
NORAPM
Returns the location of the Ethernet ID or system ID in DI:DX.
This interrupt is a
NORAND Proprietary System interface.
On Entry:
AH = 53h
AL = 80h
BH = 0Fh
DI:DX = Segment:offset of ID structure
On Return:
If successful:
Carry = 0
DI:DX = Ethernet or system ID
AH = 0
AL = Undefined
If NOT successful:
Carry = 1
AH = Error Code
AL = Undefined
The format of the ETHERNET ID structure is:
typedef struct {
UC
id[6];
// the actual ID
} ETHERID;
INT 15h, Function AX = 5380h, Subfunction BH = 10h: Set Key Click Parame-
ters
NORAPM
Sets the key click parameters.
This interrupt is a NORAND Proprietary System
interface.
On Entry:
AH = 53h
AL = 80h
BH = 10h
BL = Frequency
(value from 0ć255)
CH = Duration
(value less than
frequency
)
CL = Duty
(value from 0ć255)
On Return:
If successful:
Carry = 0
AH = 0
AL = Undefined
If NOT successful:
Carry = 1
AH = Error Code
AL = Undefined
