Agent Host Drive A
When the administrative host is using the Preboot Manager application, the Agent can
boot and run applications from host floppy drive A. INT13 calls intended for the Agent
floppy drive A are redirected by the Agent extension to the host floppy drive A. All other
INT13 calls are passed along to the original interrupt handler. The Manager application
can receive the Agent drive A interrupt and interpret the commands. It then calls its own
INT13 handler to read or write the requested sectors to host drive A. Both Manager and
Agent serial version software use Xmodem protocol for all transfers.
The floppy drive redirection feature permits support personnel to remotely administer
two vital tools on the Agent system:
•
PC DIAG diagnostics package from Unicore Software (available through Award
Software as part of the Manager application).
•
AWDFLASH BIOS flash upgrade utility. (in batch mode, this means giving the
parameters at the command line; e.g. awdflash <filename> /Sn/Py, DO NOT USE
INTERACTIVE MODE!!!)
Select Enabled to enable this feature, default is Disabled.
Agent after Boot
In the "standard" Agent product, Agent software continues to function after the operating
system loads. However, some non-DOS operating systems are not compatible with the
Agent BIOS extension, so the Agent should disable when the OS loads. Selecting
Disabled turns off the Agent software just as the BIOS transfers control to the operating
system. Default is Disabled.
Award Baud Rate
Select the speed at which the UART is to operate. Default is 19200. When using the
Preboot Manager on the host, always select 19200 baud.

Connection
A null-modem cable is a serial cable
designed to connect two PC’s. Each
end has a 9-pin, female RS-232C
connector. If you are creating your
own 9-pin cable, connect the two
ends through the cable as shown
here.
