File Comment CD Bench V1.00. This program checks the data transfer rate of your CD ROM drive at different CPU usage levels. When being run, it creates an file named CDBENCH.TXT in your current directory. CDBENCH has been written using the WATCOM compiler (V10.0) and the DOS4/GW extender (V1.97 professional). It simulates an CPU usage level while reading from your CD ROM drive. This is done by using the timer IRQ which has been reprogrammed for this. By Martin Hoffesommer.
