The interrupts were used to call bios commands. The whole DOS was only a tiiiny line between the bios. In fact, I think it really was only “DISK” os. Edit: ht

DOS only did file system operations and a few date/time calls
- pjmlp 1y agoAnd since I listed all the books I used routinely I didn't know that. Parent, > I should know the answer to this, but was using the BIOS the only way to interact with hardware like disks, mice, and keyboard? First link from your URL > READ CHARACTER FROM STANDARD INPUT, WITH ECHO Also drivers loaded via config.sys would extend MS-DOS, and be exposed via additional interrupts, e.g 0x33h for mices. Now is interrupt 0x33h populated by MS-DOS, after loading a mouse driver configured in config.sys, still MS-DOS API or not?
