Notes On Pcmcia Adapters; Troubleshooting - MikroTik RouterOS v2.9 Reference Manual

driver name. The device drivers can be removed only if the appropriate interface has been disabled.
To remove a device driver use the /driver remove command. Unloading a device driver is useful
when you swap or remove a network device - it saves system resources by avoiding to load drivers
for removed devices.
The device driver needs to be removed and loaded again, if some parameters (memory range, i/o
base address) have been changed for the network interface card.

Notes on PCMCIA Adapters

Description
Currently only the following PCMCIA-ISA and PCMCIA-PCI adapters are tested to comply with
MikroTik RouterOS:
• RICOH PCMCIA-PCI Bridge with R5C475 II or RC476 II chip (one or two PCMCIA ports)
• CISCO/Aironet PCMCIA adapter (ISA and PCI versions) for CISCO/Aironet PCMCIA cards
only
Other PCMCIA-ISA and PCMCIA-PCI adapters might not function properly.
Notes
The Ricoh adapter might not work properly with some older motherboards. When recognized
properly by the BIOS during the boot up of the router, it should be reported under the PCI device
listing as "PCI/CardBus bridge". Try using another motherboard, if the adapter or the PCMCIA card
are not recognized properly.
The maximum number of PCMCIA ports for a single system is equal to 8. If you will try to install 9
or more ports (no matter one-port or two-port adapters), no one will be recognized.

Troubleshooting

Description
• My router shows that the ISA interface is invalid
The system cannot load driver for the card. Try to specify different IO or IRQ number
