I found something very interesting while poking around the x10 file structures.
I found these 2 lines:
poolAdd({url:'stratum+tcp://nist5.mine.zpool.ca:3833',pass:'x11=1,quark=1,qubit=1,groestl=1,nist5=1',priority:'6',algo:'nist5',extranonce:true});
poolAdd({url:'stratum+tcp://groestl.mine.zpool.ca:5333',pass:'x11=1,quark=1,qubit=1,groestl=1,nist5=1',priority:'5',algo:'groestl',extranonce:true});
So I am guessing either the 2 new algos are nist5 and groestl, or they originally had nist5 and groestl and decided to change the algos to skein and myr-groestl.
I also found this line:
sudo mv sgminer_300MHz_fix_NoHW /opt/scripta/bin/sgminer
So I am assuming they have their own custom sgminer with a fixed clock rate so there goes the overclocking dream.
Guess someone at Baikal didn't remove all their traces. Now I wonder how would we get nist5 and groestl back on there. LOL.
I ran across the 300Mhz_fix line as well. If you look at early screen-shots that Baikal provided, you can see the miner chips are running at 420mhz, but producing the same hash-rate they are now (at 300) on our machines. I suspect this is the cause of the efficiency increase from the original stated numbers as well.
The poolAdd lines you found are _very_ interesting. I had myself somewhat convinced that someone was/is indeed using these things to mine groestl.
