Hi all

Z9 (not Z9 mini) FW with unlocked frequencies is available for community for free

ANY OVERCLOCKING YOU TRY - ON YOUR OWN RISK
Original frequencies are 500 and 550 MHz. But almost all Z9 from first batches are good at 650 MHz (+20% hashrate)

It is based on bitmain Antminer-Z9-DEFAULT-500-DUAL-MODE-201808280957.tar.gz firmware, only minor modifications were made - freq unlocking, adding freq list, adding links and donation addresses
here they are at a glance:

Code:

# diff -qr --no-dereference z9_orig/tmp z9_mod/tmp
File z9_orig/tmp/dev/initctl is a fifo while file z9_mod/tmp/dev/initctl is a fifo
Files z9_orig/tmp/usr/bin/cgminer and z9_mod/tmp/usr/bin/cgminer differ
Files z9_orig/tmp/usr/bin/compile_time and z9_mod/tmp/usr/bin/compile_time differ
Files z9_orig/tmp/www/pages/cgi-bin/minerAdvanced.cgi and z9_mod/tmp/www/pages/cgi-bin/minerAdvanced.cgi differ
Files z9_orig/tmp/www/pages/cgi-bin/minerConfiguration.cgi and z9_mod/tmp/www/pages/cgi-bin/minerConfiguration.cgi differ
Files z9_orig/tmp/www/pages/minerStatus.html and z9_mod/tmp/www/pages/minerStatus.html differ

cgminer is modified using disassembler and bytes patching

My collegue, efudd https://bitcointalk.org/index.php?action=profile;u=2271429 is working on the same task, but with more features/support etc. So you have an option to have a deal with him - check topic nearby

PS I'm not a Z9 owner, and had a chance to test modified cgminer only at 1 machine.
PPS Provided as is, no modifications or further improvements planned as for now
