Introduction and Overview
In Select 3, RamFS was updated to align its SWIs with those provided by ADFS, specifically, adding RamFS_MiscOp and RamFS_SectorDiscOp with the same offset that they have within ADFS. Unfortunately, under RISC OS 5, a new SWI - DiscOp64 - was added immediately after the DescribeDisc SWI. In order to remain compatible with this system, RamFS no longer follows the same SWI numbering scheme as ADFS. The following SWIs are provided by RamFS :
| SWI number | SWI name |
|---|---|
| &40780 | RamFS_DiscOp |
| &40781 | RamFS_NOP |
| &40782 | RamFS_Drives |
| &40783 | RamFS_FreeSpace |
| &40784 | RamFS_NOP |
| &40785 | RamFS_DescribeDisc |
| &40786 | RamFS_DiscOp64 |
| &40787 | RamFS_NOP |
| &40788 | RamFS_NOP |
| &40789 | RamFS_NOP |
| &4078A | RamFS_NOP |
| &4078B | RamFS_NOP |
| &4078C | RamFS_MiscOp |
| &4078D | RamFS_SectorDiscOp |
