The system resources are divided between all installed components, within the supported operating systems. A maximum of 16 interrupts (IRQ 0-15) can be addressed, thus problems may arise when new components are installed. In order to properly install your device in this case, use the DriverChoice program located on the installation diskette. Please read the manual carefully in order to avoid any mistakes.

1.2.1 HighSpeed Driver
This driver allows the highest transfer speed. It requires a free IRQ. Please read chapter 2 for system requirements for use of HighSpeed Driver (recommended for experienced users only). If you meet one of the following errors while running your drive with this default driver please use the compatibility driver:
- Reading errors of the device
- Errors on device recognition (due to a occupied IRQ)
1.2.2 Compatibility Driver
This driver differs from the High Speed Driver mainly by the fact that it does not occupy an IRQ. Choose this driver if any of the above defined errors occur with the HighSpeed Driver.
If errors still occur with this driver while running your device please use the Windows Standard Driver.
