Chapter 2 Hardware Installation and IO-IRQ
2.1 IO-IRQ Configuration Utility
Before installing any driver for C114HI in the system, it is necessary to run DOS
configuration utility,
IO-IRQ.EXE , to configure the ports, such as I/O address, IRQ,
Interrupt vector, etc. The utility is in the API-232 (DOS/Windows 3.x) driver
diskette. And select "
C104 family " for C114HI to configure.
The C114HI uses on-board EEPROM to save the board's configuration which can
be accessed (read or written) via the Configuration Access Port ( CAP ). While the
JP1 jumper cap of C114HI is removed, the CAP address is always equal to the same
address of the first port. When the JP1 jumper cap is installed, the CAP address will
be forced to 0xA700.
To save time, please determine in which operating system, e.g. Windows or OS/2 or
SCO UNIX, the C114HI board will be used. In order to ease the configuration, the
commonly used I/O address and IRQ combinations supported by most popular OSs
have been collected in the IO-IRQ utility. Press "
F3 - Select OS Compatibility " on
3rd level menu to bring the suggested list and choose a proper one. You can,
however, enter the I/O and IRQ manually if none of the items is suitable.
For example, if the C114HI board is to be installed under SCO UNIX system as the
primary (first) four port board, using SCO UNIX system serial driver, here is one of
the possible settings,
a. Press " F3 - Select OS Compatibility " on 3rd level menu.
b. Then choose the entry of " SCO UNIX 1 (Arnet Compatible...) " which will
designate the C114HI's I/O base address to 0x280, IRQ to 4 and interrupt
vector to 0x2C2.
Be careful not to conflict the I/O address and IRQ of the C114HI board with the
existing board's.
