A bit more research; seems the card ROM chip may be write locked.
Is your ROM chip one of these: Pm25LV512, Pm25LV010? Short the ROM chip:

I have renamed the ROM to 5 characters and the problem persisted, I read some info about the error problem and I think the ROM is probably locked, where do I find the Pm info you mentioned in your post, does it appear on the card or via the PC. RE shorting the ROM chip, I assume this means the dreaded solder?

You need to look on the ROM chip for printed ID.
I have a picture of a 25LV512 on this page (ignore the "C", makes no difference):
The linked page shows a picture of a jumper applied accross the pins 3 and 8 for the "hardware unlock".
This following page describes a "software unlock":
Google "error 0fl01 unlock" for more links.

Checked the Rom ID for the cards, they don't seem to be the the 'locked' numbers.
Card 1 - ATI X800XT PE - ID 4A50 - Rom ID - 25P05AV (B4O6B)
Card 2 - ATI X800X - ID 4A4B - Rom ID - 25P05AV (9422B)
The roms are 128kb, so I tried the 128kb rom from the mac elite site with same results, the error message after reporting 'invalid BIOS image'. I'm totally stumped, first my 6800 and now this, I guess the graphic card gods are angry at me!

I finally managed to flash the cards using the reduced 64k ROM. I started from scratch, re-formating the floppy and USB disks to PC format, previously I had just erased them. I used the info on the mac elite site and bingo, not sure what I was doing wrong the first time but I assume it was a DOS command line error. So the result, two very nice X800XT''s. It's a shame about the lack of DVI so I will now try to flash a couple of 6800 ultras I have lying around. Thanks, as always, for the advice and info.

I started from scratch
That is always a good policy when strange things are happening!
It's a shame about the lack of DVI
Watch for Radeon FireGL X3 cards, They give DVI through both ports.
Sometimes, you can find a real bargain on them, and, if you look, there are even a few new ones around.
