Entry
R0 = pointer to a block
Offset Meaning
0 Information word for CDFSDriver module :
Bits Meaning
0-5 The number of CD commands recognised, currently 31, maximum 63
6 If set then use the SCSI 1 read data command
7 If set then use the SCSI 1 seek command
9-31 Reserved (must be zero)
4 Number of times registered (should be set to zero and will be updated by CDFSDriver)
8 Number of drive types recognised by this driver
12 Unused (must be zero)
16 Unused (must be zero)
R1 = pointer to a 1-word special tag (&EE5OEE50), followed by handler code
R2 = pointer to workspace for the soft-loadable module (passed in R12 to the handler)
Exit
Offset Meaning
12 A pointer to a routine to convert logical blocks to minutes, seconds, frames
16 A pointer to a routine to convert minutes, seconds, frames to logical blocks
This call registers the soft-loadable driver with the CDFSDriver module. The block pointed to by R0 on entry must be in RAM, whereas anything else, i.e. the code for each CD _SWI, can be in ROM. The block must stay put in the memory so that CDFSDriver can check it when detecting drive types.
