Andy,
Many thanks for the fast reply, all understood on the xc3028.fw front.

Ah, at last we've found my field! Yep all understood, I do have access to the equipment that you specify
and I've already eliminated a lot of the variables you mention. Maybe I'll have a dabble one day in the "shed",
purely for my own interest, or maybe it would be easier just build my own myth box! ... a project
for another day ............
Meanwhile many thanks for all your support over the past month
All the best
Steve

Subject: Re:Re:Re: ROM DUMP from ACER 500
Andy,
one final question (which I really should know the answer to, to be honest!)
I've seen various attempts on the web to get the ACER aspire 500/510 working with MythTV and I'd
like to be able to assist if possible. As a first pass I'll probably just create a list of steps needed.
As well as the ivtv stuff, I've had to add various other bits and pieces of code/firmware for example the b43 (wifi) drivers,
correct lirc files etc. So, I've somewhat lost track of what I REALLY needed to do and what was just a "false path" experiment.
I can track down most things in my records, but one file that I'm not sure about is the xc3028.fw file.
Is this part of kernel or do users have to find it elsewhere on web ?
>>There's a minor difference for the two cards EEPROMs at offset
Interesting : certainly one card is better at picking up weak (UHF) signals than the other, at first I thought it was the
difference in the internal coaxial wirings, but swapping them over suggests that this is probably not the case: Maybe there is
an updated revision? Of course it could just be due to simple manufacturing tolerances. I'd be interested to know if anyone
else out there sees any difference.

Good - the change worked and your card load correctly.

No that's not a problem.
I don't know what the encoding means though:

Obviously the "ab 12 18 07" at offset 01 is just a copy of PCI Subsystem
Vendor ID and Product ID for the MPC718 (12ab:0718).
There's a minor difference for the two cards EEPROMs at offset
0x14-0x15, which may be either part of a revision or serial number.
As more users with these boards report what they have, maybe I can
figure out what some of the other bytes mean.
> I think this is what you needed?
Yup. I'm going to push a cleaned up set of changes for the cx18 driver
to dump out the eeprom for MPC718 boards.
Thanks for all the desoldering, photos, and testing. DVB-T for this
board wouldn't have been working without your efforts.
Regards,
Andy
