Hi Carl-Daniel,

At the moment I am still waiting for the end of the write flash command, which is running since 23:22 CET yesterday (So that are 8 hour running).
If I take into account the too long timing you were experiencing during read, the expected write time (with my 3x speedup patch) is roughly 9 hours.
As Homer says: Doh!
I had to stop the writing again (probably after 8,5 hours, because I wasn't expecting to wait so long and I needed my computer which ran the ssh session elsewhere. So I had to restart the process in a gnu screen session today morning and left it running. Excuse me for that dumb idea to not running the flashrom in a HUPable situation.
Erasing was complete at aprox 23:38:30 , so roughly after 13 minutes, which is much better. Up to now, I am waiting 8 hours to see any additional reporting, but flashrom is still running.
It might make sense to abort if it is still running after 12 hours total (4 hours after your mail). If you abort, please read the chip afterwards and upload the read file here: http://wedgewww.dyndns.org/uploader/
Yes, I will do so.
By the way. The first reading tests I have done ( svn1048, 1048+3xBP-patch and 1048+3xBP-patch+no_delay-patch) resulted in three identical binary files. I just double checked that with an md5sum.
I will try the test with a first spi command later and report again.
Thanks.
As you expected, the first spi command fails all the time. I added my normally detected spi flash device and retried it, which causes the same error:

I just sent a progress bar printing patch (OK, it is a really nasty hack) to the list. If you decide to abort, please use the progress printing patch together with the 3x speedup patch. Read/erase time shouldn't suffer that much from progress printing, and write probably won't be slowed down that much either.
Lets see how far it will be tonight and then I will restart it. I received my backup BIOS flash today, so I will first install the new flash and see if that PC runs fine again. If so, I will make a short setup to flash the bricked BIOS externally, so that we still get forward in with the Bit-Pirate issue.
Cheers,
Daniel
