Hi,
as someone already pointed out, we need to enable flashing first on the board using a GPIO pin. I have attached a patch for flashrom that enables flashing on the HP DL145 G3. I tested it on the DL145 I have here.
Please specify the board on the commandline, like in # ./flashrom -m "hp:dl145_g3" -E
The patch is probably not ready for primetime, maybe someone can review it?

- b = inb(0x0cd7) | 0x24;
- outb(b, 0x0cd7);
Any chance to find out what hardware is listening at 0xcd6/0xcd7?
Is that covered by PMBASE or GPIOBASE of the southbridge, or the SuperIO?
Stefan
The hardware listening on these ports is the BCM5785 (HT1000 southbridge). Basically, the code just controls 2 GPIO pins that are connected to WP and TBL of the BIOS chip.
