1747-UM001A-US-P - March 2000
Installing Software 6-3
Installing software from a remote PC through COM2
This boot method makes a remote PC appear as a floppy drive on the open
controller. This enables the open controller to boot from a bootable floppy
in the remote PC floppy drive, after which you can transfer software to the
native IDE drive.
Requirements
•
1747-OCVGA1 or 1747-OCVGAE module, monitor, and keyboard.
You use the monitor and keyboard connected to the open controller, not
the remote PC.
•
remote PC (laptop or desktop)
•
remote boot-up utility (
hostsvr.exe
) on the remote PC (this utility is
on the diagnostic/utility disk that comes with the open controller)
•
9-pin null-modem serial cable (such as catalog number 1747-OCSBC)
•
bootable floppy disk in drive A: of the remote PC (use
format n : /s
to make a floppy disk DOS bootable)
Considerations
•
Some operating systems, such as QNX, can’t be loaded from a remote
PC in this manner because their built-in floppy drivers break the BIOS
connection.
•
This method allows access to the remote PC floppy drive only, not the
hard drive.
•
The keyboard of the remote PC is inactive. Using the keyboard of the
remote PC breaks the host/server connection.
