Vista LM104-P50 manual Software Driver Installation, DEVICE = DRIVE \PATH\ LM104INT.SYS SWITCHES

Software Driver Installation

The LM104-P50 module includes two MS-DOS software drivers: one that is interrupt driven (LM104INT.SYS) and one that uses polling (LM104POL.SYS). The interrupt driver is used in most cases.

First, copy the files on the distribution diskette to a drive and directory on the host system.

For the interrupt driver, add the following line to the system’s CONFIG.SYS file:

DEVICE = [DRIVE:] [\PATH\] LM104INT.SYS [SWITCHES]

For the polled driver, remove any shorting jumpers on JP5 and add the following line to the system’s CONFIG.SYS file:

DEVICE = [DRIVE:] [\PATH\] LM104POL.SYS [SWITCHES]

Where [DRIVE:] and [\PATH\] is where the driver files were copied to.

Valid switches are as follows:

/Onn describes the output buffer count, where 2 O nn O 90. The default is 8.

/Inn describes the input buffer count, where 2 O nn O 90. The default is 8.

/Pn selects the base I/O address. Set jumper JP4 on card to match.

1Base Address 1E0 (default)

2Base Address 300

3Base Address 310

4Base Address 320

/Dn assigns the MS-DOS device name, LON[n], i.e. LON1, LON2, etc.

/Z inhibits auto flush cancel.

/Qn selects the IRQ level (LM104INT.SYS only). Set jumper JP5 on card to match.
