(SWI &41260)
| Entry | |
|---|---|
| R0 | Pointer to Driver Information Block |

| R2 | Pointer to workspace for the soft-loadable module (passed in R12 to the handler) |
| Exit | |
|---|---|
| R0 | Block updated |
Use
The purpose of this call is to register the soft-loadable driver with the CDFSDriver module.
Notes
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.
