I discovered the problem, it was from PLCC32 to DIP32 adapter, two pins were short-circuited ... Chinese thing
Now I have a new problem...loops to "found non-ATA66 cable"

I never saw one myself but there were others who did. You might be bale to find one linked here somewhere, unfortunately the main thread where you might have looked was accidentally deleted some while back. 😞

You could write the 512K image to it anyway. Or somehow increase the image size to 1M so it's happy.

You could get a 512K ROM chip and use that.

When I try to program your rom in 49LF008A I have an error0_1530164617042_C4.JPG
What I make wrong?

There is no ME etc that requires a different file for the complete rom.
