TROUBLESHOOTING General Problems PROBLEM CAUSES Unable to access CD-ROM Drive. The information in your CONFIG. SYS or AUTOEXEC. BAT or both files might be incorrect. Some BIOS that include power management features use IRQ14 or IRQ 15, which should be reserved for IDE devices like your CD-ROM Drive. Check the LASTDRIVE= entry in your CONFIG. SYS file. You might have to set the drive letter to one higher than your actual last drive letter. [. . . ] In this way, the drive will achieve lower data transfer rates at the inner tracks and higher transfer rates at the outer tracks. Thus using some or older benchmarking utilities, such as WinBench 96, will give lower data transfer rates because these utilities use the drive's inner tracks for its performance tests. A disc will occupy only the inner tracks when it is not full. Thus, because of the way your CD-ROM Drive accesses data (see preceding explanation on CAV technology), the drive will achieve lower data transfer rates. [. . . ]
