Some pcmcia device works only with lower ioport ( ioport < 0x300 )
and does not work with higher ioport ( ioport > 0x400 ).

Actually, it is difficult to find unused ioport in this lower area.

One solution is to use PNP BIOS to get used ioport.
but pre-1995 system does not have PNP BIOS.
I'm not sure the recent system have PNP BIOS.

Another solution is to use ACPI BIOS.
but pre-1998 system does not have ACPI BIOS.

ISA slot card is no longer sold in the PC store,
but on-board legacy devices still use this lower ioport.

Best Regards
