0.98 works better for me than 98.1
I see there is a lot of people how stuck with firmware upgrades. I write it how I do because I never had a problem after upgrading.
1. ssh to the miner
2. shut down cgminer.
3. run enablecores
4. click reboot
5. ssh into the miner
6. shut down cgminer
7. make the upgrade
8. I never click on reboot, just shut down the miner, wait a minute
9. turn on the miner
10. go to ugprade page -> ctrl+f5
11. if you like install bertmod.
Hope it helps for someone.
One sentence about cooling.
I made a fuckin good cooling for the jupiter, I could cool it down until 26-28C on max load verey time. But Phoenix has right, these boxes runs better warm. For me not 70C but between 45-55C. Less hw and a bit better hash.
Two firmware updates for me so far. Didn't do that, bot even half of it. Not had a problem
1. DL the update
2. On the KNC miner interface click update and select that download and apply it.
3. Click restart cg miner in the KNC interface.
Nothng else at all. Checked it after in Putty, but all was fine. lol
