DOS
This section is specific for troubleshooting under DOS. For general problems and
solutions, please see previous Section “General Troubleshooting”.
1. After executing MX-DRV.EXE, error message “MOXA C218Turbo Series
Multiport Board at base memory [XX000] not found!” appears.
a. Make sure you’re using the right driver. Please note that C218 Plus board
requires version 3.x driver while C218Turbo board requires version 5.x
driver.
b. Check if the board is properly plugged into ISA/EISA bus slot.
c. Check if the Memory Bank and IRQ settings in SETUP program are same as
the settings on board.
d. Examine your PC hardware configuration thoroughly such as Shadow RAM,
SCSI device configuration, network interface card, VGA adaptor, and so on.
Any device, which occupies memory bank, should be prevented from
colliding with the memory bank used by MOXA intelligent boards.
e. Examine your PC software configuration for memory management program
such as EMM386.exe and make sure they will not use the memory bank used
by MOXA intelligent boards. For example, if the memory bank of
C218Turbo set to c8000, the EMM386.EXE in CONFIG.SYS should be set
as follows: device = c:/dos/emm386.exe c800-cbff noems (or ram). Please
note that you should reserve memory bank for the length at lease 16k bytes
for each C218/C320 boards. You can use the F4 “Find Free Bank” function
of DOS API-232 configuration utility “SETUP” to help find the system’s free
bank.
f. Try the memory banks other than C800H, CC00H. Some mother board BIOS
may occupy these memory areas.
2. After executing MX-DRV.EXE, error message “MOXA C218Turbo Series
Multiport Board at base memory [XX000]: IRQ test failure!” appears.
This indicates MOXA board is found but the IRQ is not properly configured or
conflicting with other adapter. Make sure there is no conflict with other adapter’s
IRQ. Check the PCI BIOS IRQ setting and make sure the desired IRQ number is
available.
