VenturCom VENIX Installation
Configuring an EPC-8 Ethernet controller to work with VenturCom VENIX requires
that the EPC-8 be configured to execute effectively with the other devices in the
system. VenturCom VENIX may also require re-configuration, depending on the
EPC-8's configuration parameters.
Configuring an EPC-8
To configure an EPC-8, execute the AUTOSET program. This program configures
the EPC-8's interrupt vector, I/O base address, and RAM buffer addresses. Executing
AUTOSET requires that the EPC be booted to DOS (not VENIX), either from a DOS
floppy or a DOS partition on the hard disk.
If IRQ3 is chosen as the EPC-8 interrupt vector, the COM2 serial port driver must be
disabled (see "Disabling the COM2 Serial Port Driver", below
Disabling the COM2 Serial Port Driver.
The VenturCom VENIX COM2 serial port driver can be disabled manually by editing
a kernel configuration file and rebuilding the kernel:
1. Edit the file /etc/conf/sdevice.d/asy. The file contains two lines:
asy Y 1 7 1 4 3F8 3FF 0 0
asy Y 1 7 1 3 2F8 2FF 0 0
The line with a "3" in the sixth column specifies a serial I/O device driver on
IRQ3. Change the "Y" in the second column of the line to "N" to remove the
device driver from future kernel builds:
asy Y 1 7 1 4 3F8 3FF 0 0
asy N 1 7 1 3 2F8 2FF 0 0
2. To remove the COM2 serial port driver from the kernel, a new kernel must
be built and rebooted:
a. Log in as root and execute kconfig.
b. Select the "BUILD A KERNEL" option.
c. When prompted, specify that the new kernel should be installed, specify the
shutdown warning time, and confirm that a shutdown should occur.
