"-w" did it, thanks. 'flashrom --help' is clear that writing is the
default when no flags are given; I thought I'd tried that.<br>

I'm still in need of guidance on the IRQ questions below.<br>

Any clues to flashrom's behavior appreciated.
I'm also trying to map out the IRQ routing for the onboard NIC and USB
OHCI adapters, and I have a few questions:
* Does the order the devices appear in LB's irq_tables.c matter?
* Linux always finds the LB IRQ table, but doesn't seem able to map
IRQs to my devices. Aren't the PCI IRQ lines mappable to pretty much
any available ISA IRQ line, or are these hardwired? Here's an example
of what I mean, from one of my tests (kernel 2.6.20.1, with PCI
debugging enabled):
natsemi dp8381x driver, version 2.1, Sept 11, 2006

2.4.x kernel port by Jeff Garzik, Tjeerd Mulder
IRQ for 0000:00:15.0[A] -> PIRQ 02, mask 0400, excl 0800 -> newirq=10
... failed
PCI: Guessed IRQ 10 for device 0000:00:15.0
natsemi eth0: NatSemi DP8381[56] at 0xfebf2000 (0000:00:15.0),
00:50:f6:22:66:ba
, IRQ 10, port TP.
Even though it "guesses" IRQ 10, which is what I set in the table, it
doesn't work. Is that because I've got the NIC's INTA pointed at the
wrong PCI IRQ in my irq_tables.c, or because of something else?
Oh and before I forget, this is harder than a normal PC, due to the fact
that the original BIOS in this winterm was for WinCE only.
Thanks for any help with the IRQ mapping, I've not done this before and
I'm not having an easy time with it.
