  • Page 16: Quick Hardware Installation

    Quick Hardware Installation To fully utilize the superior feature of flexible hardware configuration design of the C168P, a quick and easy method of installation is designed for users, which absolutely free the users from hardware configuration effort, i.e., installation without running configuration program: Io-irq.exe. Simply always short the jumper JP1.

  • Page 17: Hardware Installation With Io-Irq Utility

    IRQ : INT Vector : 0x1C0 Because the ASIC-designed C168P has no switch and no jumper for configuring manually the I/O address, IRQ, INT vector, etc. of the boards, you must run the software utility, Io-irq.exe, in the driver diskette under DOS system to change the hardware configuration.

  • Page 18: Io-Irq Utility And Hardware Configuration

    If you are installing multiple boards, insert one board at a time and configure it using the Io-irq program before inserting the next board. This is to prevent conflict between two boards with same default hardware settings. The C168P has the following default (factory) settings, I/O address: IRQ: INT Vector: 0x1C0 Configuration Access Port (CAP): 0x180 4.
