That would explain why you don't get any probe response. An interesting
experiment would be to write some random image to the chip with a known
good programmer (your mainboard?), then force read the chip in the
HPT360. If that works, you only have to handle WE#. If it doesn't, there
are deeper issues that need to be fixed.

Following the policy of merging code early as long as users won't trip
over it, change CONFIG_ATAHPT to default to no, and the patch is

If you merge the current tree with your patch, a conflict will arise in
flashrom.c. Suggested resolution:
