6-4 Installing Software
Steps
1. Connect a serial port of the remote PC to COM2 on the open controller.
You can use the 1747-OCSBC null-modem serial cable.
2. Place a DOS bootable floppy disk in drive A: of the remote PC.
3. Run
hostsvr /com
n
on the remote PC, where n is the COM port on the
remote PC that is connected to the open controller.
If the remote PC is running Windows 95 or Windows NT, you must
reboot to MS-DOS mode to use
hostsvr
. This utility won’t run reliably
in a DOS shell.
This utility displays an information screen on the remote PC. Once you
escape from the display, the remote connection ends.
4. Make sure COM2 on the open controller is configured for RS-232. Refer
to "Using the Serial Ports" on page 7-2 for information about
configuring COM2.
5. Change BIOS settings on the open controller to boot from drive A: first,
then drive C:. See chapter 3 for additional BIOS information.
6. Cycle power to the open controller.
During system boot, the open controller monitor displays this message:
COM2: Emulating Drive A:
If there is not a bootable floppy disk in drive A: of the remote PC, the open
controller will boot from the C: drive of the open controller, as long as the
C: drive is bootable. If the open controller boots from the C: drive, you can
still access the A: drive of the remote PC, as long as
hostsvr
is running on
the remote PC.
Once you boot the open controller through this configuration, drive A: on
the remote PC appears as drive A: on the open controller. You can use drive
A: on the remote PC to install software on the open controller. The open
controller doesn’t have access to any other drives on the remote PC.
!
ATTENTION: Don’t use the keyboard of the remote PC
because that would disrupt the remote PC connection and quit
hostsvr.
