SlotDev

#include <Start.h>

typedef struct SlotDev { Size Offset Description

char sdExtDevID; 1 0 External device

char sdPartition; 1 1 Reserved

char sdSlotNum; 1 2 Slot number

char sdSRsrcID; 1 3 SResource ID

typedef struct SCSIDev { Size Offset Description

char sdReserved1; 1 0 Reserved

char sdReserved2; 1 1 Reserved

short sdRefNum; 2 2 Reference number of driver

typedef union DefStartRec {

SlotDev slotDev;

SCSIDev scsiDev;

typedef DefStartRec *DefStartPtr;

Notes: This structure is used in calls to GetDefaultStartup and

SetDefaultStartup. The two union members, slotDev and scsiDev

correspond to the different types of devices that can be connected.

When a SCSI device is connected the sdRefNum field will contain a negative

number (the SCSI device's driver reference number).

When a slot device is connected the sdRefNum field will contain a positive

number and the sdExtDevID field will identify the device's driver, the

sdSlotNum field will identify the slot ($9 through E) and the sdSRsrcID

field will give the slot resource identification.
