(Table 00287) Values for SCSI opcode: 00h verify interface. Clears carry flag and returns if function is available 01h returns the ID of the INT 13h Handler in a NULL terminated string of. Length less than 40 byte including the terminator.. The string is stored in the buffer pointed by p_buf. 02h device mapping info. The caller provides a one byte buffer.. The handler stores the Int 13h Device ID (80h or above) in the buffer.. It stores 0 if that target does not exists. 03h execute SCSI command 04h device reset 05h SCSI bus reset
