>Description:
when using the ex (4) driver on an Intel EtherExpress Pro 10/+ NIC in ISA PNP mode I get:

ex: WARNING: board's EEPROM is configured for IRQ 0, using 5
ex0: <Intel PRO/10+ or compatible adapter> at port 0x200-0x20f irq 5 on isa0
ex0: PnP config, 16-bit bus, board id 0xfff, stepping 0xf
ex0: Ethernet address: ff:ff:ff:ff:ff:ff
ex0: if_start running deferred for Giant

However, when disabling PNP for the NIC I get:

ex0: <Intel Pro/10+> at port 0x300-0x30f irq 11 on isa0
ex0: Manual config, 16-bit bus, board id 0x202, stepping 0x0
ex0: Ethernet address: 00:a0:c9:29:f1:29
ex0: if_start running deferred for Giant

/boot/device.hints in both cases does not contain any reference to the ex driver.
The PC is a 10 years old 486; so maybe it is a BIOS issue?

pnpinfo (when the NIC is in PNP mode) says:
