It handles floppy disks (double sided, double density), hard disk drives, and CD-ROMs. Maximum iS-DOS disk partitioning size on a hard disk is 16 MiB.

Unlike TR-DOS, iS-DOS is resident in random-access memory (RAM), and thus reduces the amount of memory available for user programs.

Versions

iS-DOS Chic[2] is a version developed for the Nemo KAY.[3] It provides more memory for user programs.

TASiS[2], based on iS-DOS Chic, is a modern version developed by NedoPC for the ATM Turbo 2+ in 2006,[4][5] supports the enhanced text mode and larger memory of that model.
