Intel DG33FB wm(4) not working after BIOS update

[Brad du Plessis <bradd%cat.co.za@localhost>]

Hi all,

Not sure if this should go to port-i386 or tech-net, please let me know 
if this is the wrong place for this.

This what I did on my Intel DG33FB motherboard:

- wm(4) device working fine on BIOS rev. 0348
- updated my motherboard BIOS rev. from 0348 to 0484
- on NetBSD 4.0_STABLE on bootup I get the following:

wm0 at pci0 dev 25 function 0: 82801I (C) LAN Controller, rev. 2
wm0: interrupting at ioapic0 pin 20 (irq 9)
wm0: PCI-Express bus
wm0: No EEPROM
wm0: unable to read Ethernet address

- reflash BIOS 0484, same issue
- did a recovery downgrade back to BIOS 0348, same issue
- install Windows XP, MAC is read fine, device works fine
- retry NetBSD 4.0_STABLE in the hope that the Windows driver has fixed 
it, same problem
- retry Windows XP, still works fine
- retry NetBSD 4.0_STABLE, same problem

This has got me confused, I originally thought that the BIOS update was 
solely responsible for the problem, but obviously the fact that it still 
works in Windows blows that theory. Has anyone got any idea?

Thanks,
Brad
