2016年7月22日 · A Disk Operating System (short: DOS) provides a software interface to magnetic disk-based storage. Commodore's Disk Operating System is built into the intelligent peripheral disk drive itself as firmware in ROM chips onboard.

Commodore DOS, also known as CBM DOS, is the disk operating system used with Commodore's 8-bit computers. Unlike most other DOSes , which are loaded from disk into the computer's own RAM and executed there, CBM DOS is executed internally in the drive: the DOS resides in ROM chips inside the drive, and is run there by one or more dedicated MOS ...
