Hmm, no helpful bootverbose messages in the pnp.c code it seems. Can you take a hand at adding printfs to sys/isa/pnp.c? Specifically, something like this: Index: pnp.c =================================================================== --- pnp.c (revision 219740) +++ pnp.c (working copy) @@ -743,10 +743,10 @@ pnp_isolation_protocol(device_t parent) printf("A Normal-ISA-PnP card (%s).\n", pnp_eisaformat(id.vendor_id)); } +#endif if (bootverbose) printf("Reading PnP configuration for %s.\n", pnp_eisaformat(id.vendor_id)); -#endif error = pnp_read_resources(&resources, &space, &len); if (error) break; That should at least list each card it finds in a verbose boot. If you get a message showing your card, then the next step is probably to see if pnp_read_resources() is failing. If it is you'd want to narrow down where it fails. If not then you'd want to trace pnp_create_devices() to see if it fails. Oh, and a 'devinfo -v' to make sure your device doesn't already exist might be a good sanity check as well. -- John Baldwin
