Configuring the PC System 57
Configuring the PC System 4
An application running on the Mac OS can use the interface driver to configure the PC
system. You can also use the driver to perform the following operations:
■ configure the disk drives available to the cards
■ set and read the status of the network driver
■ configure the communications port
■ configure the parallel port
■ define the key combination that switches focus between the PC system and the
Macintosh
This section describes the routines that perform these configuration tasks. Each routine
lists the parameter block settings associated with that particular routine.
rsSetDriveConfig 4
You can use the rsSetDriveConfig control routine to configure each of the PC
system’s fixed drives (A:, B:, C:, and D:). These drives can be configured as a floppy
drive, Macintosh file, SCSI partition, or have no corresponding driver.
The status code for this routine is rsSetDriveConfig = 500.
The application running on the Macintosh computer should call rsSetDriveConfig at
least once before starting the PC system. If you want to change the drive configuration
after the PC system has been started, you can also call this routine. When you do this, the
drive configuration does not change until the PC system is restarted.
