Re: NI ATMIO-16E-10 Board..

Actually.. it seems that starting on line 319 of ni_atmio.c the
following curiosity emerges:

#undef __ISAPNP__
#ifdef __ISAPNP__
static struct isapnp_device_id device_ids[] = {
        { ISAPNP_DEVICE_SINGLE('N','I','C',0x1900,'N','I','C',0x0000), },
        { ISAPNP_DEVICE_SINGLE('N','I','C',0x2400,'N','I','C',0x2400), },
        { ISAPNP_DEVICE_SINGLE('N','I','C',0x2700,'N','I','C',0x2700), },
        { ISAPNP_DEVICE_SINGLE_END, },
};
MODULE_DEVICE_TABLE(isapnp, device_ids);
#endif

Thus, for the rest of the .c file __ISAPNP__ is undefined and thus kernel
isapnp support is disabled in this driver.  Is isapnp in the kernel broken
for this driver?  Is that why someone added that #undef __ISAPNP__?  It
seemed to be working fine in CVS a few months back...

Or is this just a minor source bug?
