There are currently 3 types of optical drive programs commonly used under DOS
1. VIDE-CDD.SYS file size 11K, memory occupies 5K, and the light drive identification capability ★★★★ drives the loading speed relatively fast
2. OAKCDROM file size 41K, memory occupies 30K light-driven identification capability ★★★ drive loading speed average
3. TRICD.SYS file size 19K, memory occupies 7K light-driven identification capability ★★★★★ drive loading speed is slow (can recognize light-driven model)
4. PTSATAPI.SYS file size 4K, memory occupies 2K light-driven identification capability ★★★★★ Drive loading speed fast (can recognize the optical-driven model and IRQ) is strongly recommended for everyone to use!
The version number I extracted from PT-DOS is 1.4 (2004). Ibid.: P

It is now recommended that QCDROM.SYS (the latest version 2.0 was only released a few days ago), which only accounts for 2KB memory, but compatibility seems to be much better than PTSATAPI.SYS, and supports UltraDMA.
