Interrupt & Address Selection
Refer to your PC-AT's documentation to avoid interrupt and address conflicts, and the
resulting possibility of system damage.
If you are using Motion Architect and you change these settings, be sure to configure
the same address and interrupt settings in Motion Architect's Terminal or Panel modules.
Interrupts
The AT6n00 is factory configured with no interrupts selected. The AT6n00 does not need interrupts to
function properly. If you want to use interrupts, select an interrupt in your system that is not already used
in the system (refer to instructions on page 4).
Interrupts that are unassigned on the AT bus are IRQ10, 11,12, and 15. If serial port COM1 is not used,
IRQ4 may be available. If serial port COM2 is not used, IRQ3 may be available. IRQ5 and 7 are defined
for parallel printer ports and one or both of these may be available if your system has one or no parallel
printer ports.
Address
The AT6n00 is factory-set to address 300H. If another card in your system uses address 300H (default
setting), select a different address (refer to instructions on page 4).
If you are unsure which addresses are used, the following address are likely to be available: 308H, 310H,
318H, 380H, 388H, 3A0H, or 3A8H.

CAUTION
Reason/Corrective Action
The operating system specified, or the default operating system (if unspecified) could not be
found by the AT6400.EXE loader program. Put the AT6400.OPS file in the same directory
as the AT6400.EXE file.
The operating system specified, or the default operating system (if unspecified) is not a valid
operating system or is corrupted. Re-install the operating system from the original disk.
An EOF character was received during the download. Re-install the operating system from
the original disk.
The port address specified while downloading is invalid. Use another address setting
(768 ≤ port ≤ 1024 in increments of 8).
An unknown option was specified on the AT6400.EXE command line.
The base port address is too high. Specify an address between 768 and 1024 decimal with the
/PORT= parameter.
The base port address is too low. Specify an address between 768 and 1024 decimal with the
/PORT= parameter.
The base port address is not a multiple of 8. Specify a valid address with the /PORT=
parameter.
A partial download was requested on the command line.
The card controller did not respond as expected. Verify that you are downloading to the correct
address. Make sure there are no other peripheral cards (network adapters, bus mouse, etc.)
at the same address. Try changing the card address.
