I get this error message during the boot:
Smart Init is disabled. IOMEM set to: 15
Using iomem percentage: 15
Error, PCMCIA vendor/id incorrect, 0xFFFFFFFF
%ERR-1-GT64010: Fatal error, PCI Master abort
cause=0x0300E483, mask=0x0CD01F00, real_cause=0x00000400
bus_err_high=0x00000000, bus_err_low=0x31000000, addr_decode_err=0x1FE0000E
It doesn't look to cause any problems for the router.
The error message came after I did this. I configured the router with reference to an IOS file which does not exist. The router was not able to boot normal anymore, so I deleted the configuration from ROM mode.
It is a Cisco 3600 router with PCMCIA card slots which is not used.
I have not found a solution to get rid of the message.
